JASPER Engines & Transmissions Reviews

I purchased a Jasper engine for my 1989 Ford F250 on 7/31/15 on the advice of my mechanic. By 6/29/19 the engine only has 1833 mile on it because the truck was not working from the day installed. It has been to the mechanic so many time that I lost count. I had to have it towed in over 5 times!! It has had two solenoids, two starters, alternator, the new water pump was leaking, antifreeze has to be added every two or three trips driving about 14 miles each. Gas mileage is 8.9 per gallon. The original mileage was 19 per gallon. The engine is always running cold even if the temperature outside is 100 degrees. I took it to one mechanic who told me that it had too much wrong for him to fix it and that nobody in my area could repair it. Guess that I need to sue Jasper.

Purchased a Jasper Engine for my Jeep Wagoneer rebuild. The Customer Service was poor at best. The telephone sales rep told me one thing but when the Engine arrived, wasn't true. I called back and talked to the Supervisor and he disagreed with me after saying he had reviewed the Sales Call and no such things were said (right!!! I know what I heard on the call). Now I'm waiting for my Core Charge refund and getting the same silent treatment. Net, POOR CUSTOMER SERVICE! I can only wait to find out how the engine actually runs (after all, it supposedly has been "tested" before leaving the factory)!

Have a 2012 Camaro SS with v8. Replaced the engine with a Jasper unit. From day 1 the oil pressure was much lower than the original engine, returned the car to the installer where they contacted Jasper. They recommended replacing the engine with another unit. So far much better oil pressure. Keeping my fingers crossed.

Purchased a Ford 5.4 litre Jasper engine for my truck, 5400.00 with install kit + labor to install. The engine was very noisy just after startup and would quiet down after about ten minutes of warm up. This problem began at day one! Very surprised because one of the selling points from Jasper was that they run/test their engines prior to shipping and this noise would have been very obvious. Jasper concluded that it was in the valve train. Had the engine removed and replaced with another and this one made the same noise, since day one again. Really don’t want to replace again, because of all the wear and tear on components, wiring harnesses, loss of work truck, etc...

I once installed a Jasper performance transmission in a Ford F450 for a customer and was just about ready to have the customer pick up the truck when Jasper called. They had sent me a non performance transmission and offered to send me the right trans or refund me the difference. I opted to install the right transmission. They paid parts & labor without sweat and had another trans at my door the next day. Another time when I was diagnosing a transmission issue I noticed the trans fluid (this was a Jasper unit) smelled slightly burnt. I contacted Jasper and they had one on the way parts and labor covered. By saying the best rebuilders I don't mean that they are without fault. Unfortunately I believe any factory rebuilt part quality is hit or miss. I've had good luck installing Jasper products for customers.

Oct 2018 I purchased a 2008 Jeep Wrangler Rubicon unlimited. On Dec 25 2018 the engine started running terrible. I had it towed to the mechanic's shop where, a few days later, I learned the engine was blown. My heart sank. I didn't have the money to purchase a new motor. During my conversation with the mechanic’s secretary she was informed, by the mechanic, that the engine was previously rebuilt by Jasper Motors. She told me to stay by the phone that she would call me back. An hour later she called. Jasper Motors was willing to ship a new motor out to be replaced. I would be responsible for the labor but Jasper's would reimburse me if it was found to be their fault. Today January 28 I received a check for the full amount. Thank You Jasper Motors. You will have my family's business if we ever need another motor! An honest company doing honest work!

I purchased a brand new engine and after 3 years and only roughly 18,000 miles on this motor went bad. Even with all my proper oil changes and any normal care I would never again buy anything from Jasper. I purchased this mainly because of warranty options, now I wish I would have seen other people’s reviews before purchasing this for my vehicle.

Bought rebuilt engine, $5,000, for 2003 PT Cruiser. Jasper shipped one that couldn’t be installed properly. After a week of trying and contacting Jasper for input, it was decided to ship a 2nd engine. This one seems to be working fine! Problem is: Jasper claims a limit of $832 for labor costs based upon 11.6 hours of labor at $70/hr. My mechanic charged $1900 which included a lot more labor hours necessary to try and get the original engine to work properly. I paid my mechanic the $1900 in good faith that Jasper would return the difference in labor cost because THEY SENT THE WRONG ENGINE. After reading other complaints about Jasper I guess I have to go to court or get a Consumer’s Affairs Investigator involved!

I bought a 2006 Ford F250 from a dealership with the brand new Jasper motor in the truck. Told me I had a hundred thousand mile warranty and 3 years. I've had the truck for 2 years and it has 50,000 miles on the motor. Well the motor has malfunctioned so I called Jasper and the gentleman I talked to was quite rude to me and told me that they would not honor the warranty. I'm paying for a truck that I cannot drive because their motor malfunction and they're refusing to do anything about it. I'm a disabled person that lives month to month and has no way to get to Dr and other appointments now because of my truck being broke down and the motor not being warrantied. Pretty sad a well-known company like that will not do anything about their warranty.

In April of 2013 I a Jasper complete 5.7L engine was installed in my 1999 Suburban. In January of 2016 after 30,000 it developed a rattle. After many discussions with Jasper they replaced the engine with a new one. In October of 2018 the engine has seized, after only 3600 miles, and Jasper will do nothing about it. They are claiming the warranty on the replacement engine reverts back to the original engine so it is no longer under warranty. Hard to believe that they would only warranty the replacement for 3 months when the engine comes with a 3 year, 100,000 mile warranty. I wouldn't recommend Jasper to my worst enemy!! When I called all I got was, "it wouldn't matter if we replaced it with 1 day left on the original motor, the new would only have a 1 day warranty. Only putting on 3600 miles over 2 years could also be the problem. If you don't run them regularly they can develop problems."

I’ve had 3 4.3 Chevy engines put in my boat this year. Everyone was a piece of crap and they won’t stand behind their warranty. I think the government needs to step in and solve this problem. I have an attorney and will be suing them for the motor labor time lost and inconvenience. This company needs to be closed!!!

My dealership purchased a remanufactured turbocharger for a 6.7 Dodge diesel, these guys put so much hype in their ad about how well made these turbos are but just after 44,000 miles the whole component has failed. No resolution from them or dealership. If you are looking for a turbocharger look elsewhere. Do Not Purchase one from these guys, read the reviews, I didn't have a say in the repair as it was warranted by the dealership. I am now having to replace my turbocharger and surely I will check out other companies. BUYER BEWARE!!!

1999 Chrysler 300M. Bought a new Jasper engine. Got it installed. It started throwing oil and leaking within 1 month. Had it removed and ANOTHER Jasper engine installed. I HAD TO PAY ALL OF THE LABOR FOR REMOVAL AND INSTALL OF 2nd ENGINE! So... the 2nd engine just threw a rod last week. I changed the oil every 3500 miles and had it done by the INSTALLER of the engine so they could keep an eye out for any issues. Guess how many miles the 2nd one had on it when it blew up last week? 75,000. Do not waste your $$$ on a Jasper engine. VERY disappointed... to say the least. I was hoping for AT LEAST 125,000 miles and it should have lasted that with regular oil changes.

This is by far the bottom of the barrel as far as engine rebuilders go! I own a Marine Service business and recently installed a Jasper 4.3 Litre Chevy Marine engine. It failed within a month! They did replace the engine after much headache. The second engine failed right at about a month after install as well. This time I told the Jasper rep that some cylinders were showing water intrusion so I was pulling the cylinder head! (They did not like this). After the head was pulled there was a 3 inch crack in the cylinder wall. Bottom line:: They said it was detonation (idiots). I was never paid a dime labor on either engine failure, Guess what, The boat is back again. Jasper engines are garbage, warranty is garbage, company is garbage!!!

Installed 3 rebuilt Jasper motors on my 2008 Subaru Outback through Jasper in the last year and a half. They said they would refund the money if they got the engine back. That would render the car useless. $4200.00 just for motor, reduced rate for labor, multiple failures, quality of product very disappointing. They said they would give us a $250.00 credit. Oh Wow then what? Take the bus with my tools... Can't even give it one star.

I replaced all the injectors on my 6.0 Super Duty with Jasper injectors. Less than 6 months one goes out. I was told when I replaced them I received a 2 year parts and labor warranty. I take my truck to the shop and was told I had a bad injector. I showed them the warranty and he said ok. They started repairs on my truck. They had to jump through many hoops to get the part then I was told Jasper will only cover $75.00 of the labor. WHAT? Where can you get a injector replaced for $75.00? Nowhere! I called Jasper and got nowhere with them. This warranty isn't worth the paper it's written on. I'll never buy anything from them as long as I live. Jasper can kiss my **!

Back in 2012, I had a 5.7 liter Jasper Engine installed in my 96 Impala SS. At the time the car had 269,000 miles. It now has 303,000 miles. The Jasper engine didn't even make it to 35,000 miles. Today it apparently blew a head gasket. It dumped a huge puddle of oil and coolant in the hospital parking lot. Today, I had it flat-bedded home. Called the Jasper tech and told him what happened. I said, "you sold me an engine that couldn't make it to 35,000 miles." He pointed out that it was installed back in November of 2012. So I am just out of luck. I asked if Jasper would step up with an extended or hidden warranty. The answer was short and to the point - "nope". Needless to say, I don't recommend buying an engine from Jasper. 35,000 miles after only 5.5 years and the engine failed. Garbage!

Very disappointed with my purchase of a 5.9 Cummins. Had fuel issues from the start. They blamed everything on fuel issues. The problem was injector pump. Sloppy rebuild pump was sucking air thru. The front shop who install engine had no clue lead me along till warranty was up. Took it to another diesel specialist who said it was a common problem with Jasper rebuilds. Would not recommend them to anyone.

Being familiar with the Jasper, IN area and some people who work at the Jasper engine and transmission factory, it was a no-brainer that I'd turn to them when a problem appeared in my daughter's 2006 Chevy Trailblazer 4.2L engine. With the first replacement, the engine was subject to dying at inopportune times, even after they said it would stop! Engine number two, about five weeks after the second oil change, I discovered the engine was about two qts low on oil. Took it to a different Jasper provider in town and explained the situation to them and after the normal initial inspection, was told there was compression loss in three of the cylinders.

1997 Chevy Silverado - My transmission failed on me while I was out of town about 5 years ago. I knew I wanted to keep my truck so I bought a JASPER. I like how they research the common issues and fix them to make it better than the original. My transmission had a long list of updates! Once I found out they are 100% employee owned and their factory is in the US... I was sold!

Engine (Cummins 5.9 diesel engine) bought Sep.2018. Installed in Las Vegas, NV. Cylinder head cracked, noticed in Yuma, AZ. Went back to LV, to replace. Found no. 1 piston installed backwards at Jasper the reason engine vibrated. Jasper paid for partial labor, & parts. Diesel Specialties replaced cyl head, & fixed piston, at no charge to me, except for 1,100.00 expenses for 2 trips Yuma to LV, motels, 4 nights car rental. Jasper made the mistake. They should make an adjustment for a refund for expenses. They said NO. Same with Diesel Specialties. Very dissatisfied.

When I take my truck to get oil change at my TRANSMISSION shop they discover a crack in my Jasper transfer case. Called Jasper, confirmed warranty is still good. Customer service confirms still under warranty, no problem. Following day, a different customer service rep calls and said I need $800 so that we can cover shipping and investigation. I burst out into laughter. I explained to the representative that from the back of the transfer case to the rear differential is perfect, from the front of the transfer case all the way to the front bumper of the truck is perfect but the transfer case in between has a crack in it. No investigation needed. Please stand behind your warranty.

Had a Jasper 5.9 Cummins diesel engine installed replacing OEM with 180,000 plus miles on it. 13 months later injector goes out. Call Jasper, they blamed me for using bad fuel. Also sorry warranty over for injectors at 12 months. Replaced injector and find out it was not properly torched to spec at 37 lbs. It was basically had tight (no quality control). 25 months rear freeze plug starts leaking. Call Jasper, "Sorry warranty up at 24 months". There is no end user customer service. They only protect their shops that use their product. Do not install a Jasper motor in your vehicle, they suck.

Like any company you don't know how good or bad they are until you have a problem. I am an ASE tech and an ACDelco master tech for 30 years now. I installed a 2005 Ford Escape engine from Jasper. On start up the lifter was making noise. I called Jasper immediately. I was told that the lifter noise was normal. What? I was told to drive for 100 miles it will go away. Then I had to explain to my customer that the new motor makes noise and it's normal? Plus pay me in full for a new motor with engine noise. That's a hard sell. But I did. Long time customer of mine so he understood. He drove it for 200 miles plus with still a lifter noise. He also called Jasper and they told him the same story. Lifter noise is normal for this engine. He was very patient but wanted the job fixed. Understandably. He paid a lot of money to fix his 2005 Escape.

Spent over $23,000 on new Jasper 6.0 diesel. Had it three weeks and left for Denver. The new engine blew and of course Jasper won't pay anything until they get the old block back! REALLY??? I'm stranded because of a new blown warrantied engine and now out motels and rental cars plus I have to pay labor out of my pocket and wait to get $70 per hour reimbursement. Of course nobody charges $70 per hour anymore so I'll be out money on a 3 week old engine. Even after spending $23,000 to begin with. Where is customer satisfaction these days??? Even tow bills for truck and 5th wheel. Come on!!

DO NOT "TRUST" that their, JASPER, "Installers" such as Lakewood Auto Inc are competent. Jasper lists business on their site and This "Jasper Installer" wrecked my vehicle, was driving my vehicle, had my vehicle for 17 months (though they were paid) took my car to a "d" BBB rated shop (found my car on the side of road) then refused to give car back! REALLY BAD HOSES on ENGINE, Cracked leaking hoses, parts invoiced "DO NOT FIT YOUR VEHICLE" - CHANGED PARTS I had just replaced without permission - QUOTED two different prices (one higher than the other by 1200.00) then charged 1000.00 Higher than the "higher quote". Car towed and towed and towed after Jasper Engine installed.

4 months ago OEM went out so I put a Jasper in instead of a used only 1000 difference. So at 3 months and 3000 miles take it in and they find a oil leak. So I cant take it back to original installer cause the engine went while on the road, over 300 miles away. So take to a local dealer who does Jasper engines. Plus a month more driving cause my other car went down. So I get that fixed and take this one in. 2 weeks later I call about mine. Mech got sick. Why it is taking so long but that is not my complaint

Bought a 6.4 Diesel engine from Jasper. Didn't even get 20000 miles out of it. The Jasper installer told me it had a 2 year warranty. 13 months after having it the crank goes out in it. Call on warranty. They said it was out a month ago. They do not stand by their warranty. They rob people of their money. Mine was 14320$. My advice is to never buy from them.

I purchased a Jasper engine at 157323, because my stock engine failed. The Jasper engine failed at 196232 miles and 41 months of service. Jasper pointed out that my warranty expired at 36 months and now the engine is "too old " to cover. I was also told that "41 months of service is an acceptable amount of life for a jasper re manufactured engine". I babied this motor, not allowing rpm's above 2500. Turns out something fell apart in the engine causing the #2 & #5 cylinders to have 25% compression. At this point it's cheaper to buy a new engine for me. Something caused the pistons to contact the valves.

I purchased a completely rebuilt Chevy 6.0 liter engine installed by a local garage. The engine runs perfectly. It's the first motor I've ever owned that idles perfectly without the expected miss now and again. Freeway mileage with my 2011 Silverado 2500 Crew Cab is 20+ mpg.

The block on the original 5.7L engine on my '93 Suburban cracked at around 225,000 miles; water in the oil = ruined engine. I arranged for a Jasper Engine from my local mechanic. That engine also had a crack in the block that was "repaired" with steel epoxy. It failed after only a hundred miles or so. Jasper completely covered the engine, and sent another engine within a week. I now have about 60,000 miles on that engine and it's running very well, doesn't use oil, doesn't leak, has plenty of compression, and I would trust it to drive across the USA.

I purchase a turbo for my F-350. My claim were not paid because of the turbo. The metal on the turbo came apart and ruin my engine. The engine only had 100,000 low miles for a diesel. The metal shaving from the turbo caused the problem. Scarring parts inside the engine. Now I have to replace my engine. Even though the turbo ruin my engine. I called Jasper. It didn't do any good. Please don’t purchase any parts from them unless you want to purchase a new engine. Turbo are garbage. DO NOT PUT YOURSELF THRU IT.

I bought a Jasper transmission through my local mechanic, who raved about them. It was significantly more expensive than my other options, but I was sold. The transmission failed, and since I was FIFTY MILES over the mandatory trans fluid replacement interval, they said no.

Jasper Engines & Transmissions are awful, awful engine rebuilders. DT466 Reman lasted 18 months before injector cup blew out, head needed to be pulled. 3 years in rear main started to leak. 4.5 years completely imploded. Asked for a discount on a new Reman. Would not give a nickel. Awful company, never again.

This is a rebuttal to Southern Cranes review and issues with a Jasper Engines unit. I am the shop that had to replace the Jasper unit you installed. The vehicle was towed to us from your customer with the engine running rough and smoking. Diagnosis found that there was a hole melted in one of the pistons. Tear down inspection of the engine found extreme heat evidenced by discolored exhaust piping and discolored turbo inlets from very high temps. Further diagnosis found that the truck had an aftermarket performance programmer installed on it at time of sale from you to your customer. Any search online of the Ford 6.4L diesel engine will show that engine is notorious for cracking or melting pistons when aggressive performance programmers are installed.

I own a 2006 Mazda MPV Mini Van which I purchased new. The trouble started when the MPV hit 110,000 miles, the engine died! I was sitting still in a construction zone and the MPV just quit, would not start back up. So off it goes to the Mazda dealer (Knoxville, TN). This dealership sucks, but it is the closest to where I live :( I have learned to dislike them as much as the junky jasper engine, that they put in my MPV at a cost of $6100.00! First the Mazda dealer told me they were putting in a "New" engine. Well its not new, it's refurbished!!! I had the choice of a "refurbished" for $3800, but I said no, that I would go with the "new" one, at $6100 hoping it would last a few years?

I purchased a 1976 Ford Bronco in July with under 3000 miles on a Jasper motor. Within 400 miles, the motor failed. I was advised to take 'Pearl' to a Jasper dealer which I did. Over a period of months, the motor was sent back to Indiana to be rebuilt, parts failed during testing there, delivery delays. Jasper refused to pay labor costs indicating that I was somehow to blame. It's my new company truck, I need it on the road, so I paid labor, $1800 and change. All the while thinking I'd have a NEW Jasper motor with another warranty. That's what Jasper is in the business of doing, right? WRONG.

Jasper Engine: I purchased a Jasper Engine for one of my customers and the engine was installed and ran for 6 months -- the engine locked up and Jasper says they have a 1 year parts and labor warranty -- they covered neither my customer is faced with installing another engine at his cost. They did nothing -- so now either he will have to take Jasper to court -- the problem is the time and money it takes to do that in the meantime his work vehicle is down and it is a $80,000 dollar vehicle -- that would cause hardship on him. Jasper Engines will not cover anything and it is the engine itself that broke or has a hole in it.

I have been doing business with Jasper Engines and Transmissions for over 20 years. Jasper supplies the highest quality products. I HIGHLY recommend them.

Excellent company to work with. Always very friendly and knowledgeable. Would highly recommend their products and services.

In July of 2014 I was on my way to Mount Rushmore in my 2002 Jeep Grand Cherokee when the cooling fan went out in Sparks, Nevada and ruined the engine. I took the car to Wayne's Automotive (who are super to do business with). They said the engine was shot and recommended a Jasper engine as a replacement. With all the parts and labor the cost was over 9000 dollars. The follow August a very loud racket started under the hood. I called Wayne's and they said no problem bring it in and they would fix it because it had a 100000 mile 36 month on the engine. They replaced the engine for no charge. I drove the car with the second new engine about 5000 and again the engine failed in Las Vegas.

I am looking for an engine for my 96 Chevy truck and when I read all reviews about Jasper Engines I see a big red flag. My best thought is to turn, run far and fast and hope the rest of us who are in the market for auto parts read the reviews first. You will save a ton of money. Less gray hair.

I bought a 2001 Chevy 3500 Express Cutaway in 2014 with supposedly 40,000 (original) miles. At 56,000 miles the transmission went out. The mechanic was under the impression it had a great warranty on it, and after checking, discovered it was a 3 year/100,000 mile warranty. In checking with Jasper, I found out that the transmission had been replaced in 2012, which meant that the transmission had to of gone out in less than 30,000 miles both times. I will never own a Jasper transmission, nor buy another vehicle with one in it. If a transmission can't last 100,000 miles, it is total junk and is faulty in all aspects of the word. Obviously they will not replace it in any way shape or form.

About five or six months ago I bought a Jasper differential. It came with a warranty. 100000 mile or 3 year the differential went out. I needed it replaced. They told me they would not have replaced the part if they knew it was for a lifted truck and upon going over the morning to you before I got the part they said that my labor would be reimbursed. They have not reimbursed my labor and I am almost sure the second if we'll go out and cost me another 3000 probably this garbage company will not reimburse me. I have tried and tried but they will not. I am contacting a lawyer and going to try to sue for my money back. Stay away from Jasper parts forever. I am actually probably going to have this one refunded and have to do it all over again if they will even do that because they are stingy and shady. Once they get your money they don't give a ** about you. You are just ** out of luck when it comes to anything Jasper.

My '05 Ford F150 FX4 engine died just over 90k miles. The only cost-effective option at the time seemed to be a remanufactured engine from Jasper. Engine and labor/parts were just under 8 grand. The engine lasted 37 months and 24k miles, 1 month past their 36 month warranty/100k. Jasper agreed to send out another engine but not pay for parts/labor which ran just under 2 grand. Jasper also took their sweet time making the shop run through hoops and tests. Get the customer taken care of and run the tests on your own time Jasper. Once engine came in engine still had problems and cam solenoids needed to be replaced.

The motor that was sent was a good running motor, the only problem was it was leaking oil and antifreeze. After following Jasper Engines advice we replaced the valve cover gaskets 3 times. We also replaced the intake gasket. Finally we were told that we should pull the motor out and they would send another motor and upon review of the testing of the motor they would repay for the 2nd installation. Of course they found nothing wrong and told us sorry there's nothing they can do. We're out $1200.00 dollars in labor not including fluids. After doing business for many years with Jasper I would never think of buying another product again. They have no Rep. that can come out to see with their own eyes what the problems are. Terrible customer service from the owners.

I was talked into trusting that Jasper motors was a good choice. Now motor #4 is still waiting to be put into my wife's Nissan. I can't get the Mechanic to call me back and have be told over and over that the district manager would probably call me. This is still under warranty. I'm an old school racer and in the 70's and 80's Jasper was more or less a boat anchor and was told "no, no, they have came a long way now. They are a lot better." I should have left the old original motor in it.

The original transmission on my '93 Sierra died at 126,000. I have read that they typically last to 90K so I decided to replace it with a new unit. The repair shop recommended Jasper toting all their upgrades including steel vs. factory nylon gears and a wonderful 3-year warranty. So $2,500.00 later I leave the shop with my once again working truck. Now it is a second vehicle for me and I hardly drive it unless I need to haul something, which is rare anymore. We just under three years and 1,500 miles later the transmission has totally died! I have lost 2 and 3rd gear and it constantly slips out of gear if I go over 25 miles and hour. So I return to the shop that installed it only to be told that it is to close to the end of the warranty and that I will be expected to pay at least $2,500 in labor. NEVER BUY ANY JASPER PRODUCT!!! BUYER BE AWARE!

Motor in my Son's 06 F150 failed, took it to my mechanic of 10 yrs. Said needed another engine, recommended Jasper over a "junkyard" motor. 7500K later out the door. About a year later with 6300 miles of the motor, the Jasper motor failed while my Son was 15 hrs away in the middle of the TX desert. Towed the truck to El Paso (we live in Houston) and flew him home. Ford dealer said this motor failed as well. Jasper sent another motor down, 4300 in labor, parts later on our way. Just got a check from Jasper for 1000 to cover the costs. WTH?? No phone call, no anything?

I am the owner of an automotive repair shop in Austin, Texas. I have had the pleasure of having to replace a 4.6L engine assembly in a 2000 Ford Mustang 4 different times because of internal part failure of the 3 engine assemblies the I purchased from Jasper engines. 1st engine had timing chain rattle noise, 2nd engine had noise in #4 cylinder which sounded like a rod bearing and the 3rd engine also had the same noise. Jasper warrantied the first 3 engines but on the fourth (three strikes and you're out!) engine I wanted a full refund of the money that I spent on the original engine.

I had a diesel engine over two months ago and it still is not running. I am out over $10,700.00. The engine starts up then unexpectedly shuts off. The mechanic is a experienced diesel mechanic. He has install two fuel injection boxes to no avail. This engine is a lemon. My old engine with over 220k miles ran better than this one.

Last September, I had a Michigan-based Jeep shop replace the engine in my 2005 Jeep Wrangler, with a Jasper engine. I drove the Jeep home to Colorado, and on the way back, the engine developed problems... overheating and no power. I called the installer when I got home, they immediately contacted Jasper, and Jasper helped me make arrangements to take it to a Colorado Jasper installer to have the engine inspected. That outfit, Predator 4 Wheel Drive, turned out to be a disaster. Not fixing anything and charging me $81.00 for the inspection and a new radiator cap. Jasper had me take it to another installer, who confirmed the engine block had a hot spot.

Have been using Jasper for many years in an automotive shop. We have installed their Gas and Diesel Engines, Auto and Manual Transmissions, Transfer Cases and Diffs. If there's ever an issue with a product under the warranty period, Jasper takes care of the customer and the shop. From the Sales Department to the Tech Department they are easy to deal with and we have never had an issue that wasn't resolved. I'm Proud to sell and install any Jasper product. Thanks Jasper.

18 months ago, Robinson Ford in Baton Rouge sold me and installed a Jasper 302 V8 long block and transmission in my 87 F150. A week after the work was finished, the engine failed and had to be replaced. 3 weeks later the second engine failed and a third was installed. In total my truck was in the shop for 2.5 months to get a working engine installed. After 5000 miles, my engine is now leaking oil and Jasper will only pay one third of the bill to $400 of $600 fix this repair. Do you think Jasper has a process for quality assurance? Do you think anyone at Jasper's cares? DON'T EVER BUY anything from Jasper or Ford Dealerships.

Purchased a JASPER Engine for my 04 Trailblazer, had issues with a hesitation, but several times they said they could not replicate. Finally did and it was a bad gasket which caused oil into the plugs, now will cost me $1000, since JASPER only really warranties the "BLOCK". So to actually have something under warranty your engine basically had to blow up. But then they would find a reason not to. To see a company built on a reputation do this is terrible. Costly Lesson and not one I will ever repeat and will remember this lesson for many years to come and will ensure all I know hear actually how this company has changed!

I recently had a rebuilt Jasper engine installed in my '96 Yukon. After driving approximately two weeks and 600 miles, the new engine developed a major oil leak, serious enough that I couldn't drive the rig any further. I was 300 miles from home, and the tow bill was over $700! The leak turned out to be a faulty "O" ring on the oil filter adapter where it attached to the engine block. The "O" ring was supplied with the Jasper engine.

So being a certified auto repair shop and having 40 years repairing cars and trucks. We have a long time client that needed an engine replacement. He compared the Ford dealer to Jasper and on our recommendation we installed the complete Jasper replacement engine. So after 13,456 miles and 15 months after the install, he brought the vehicle back for a fluid leak. It turned out to be a leaking intake manifold gasket. We used the gaskets provided by Jasper when we purchased the engine. I called them and they said sorry the warranty on that is only for one year and is a part only warranty no labor. Well, the warranty on their engines is three years or 100,000 miles. So I guess they don't consider their gaskets something that should be covered. I did learn a lesson. I will never purchase another Jasper product. I have been using their reman products for 15 years and had one issue with a cylinder head about ten years ago, their warranty service at that time was fine, but I guess everything changes. I will use only manufacturer supplied major components from now on.

On a trip from CO to FL, our F-250 truck transmission gave out and was replaced at an AAA-approved garage with a Jasper. All lines and cooler were also replaced at additional cost to conform to their warranty rules. Within 8 Months and LESS than 5000 miles later, the Trans gave out at home in CO... Again back to a recommended approved Jasper Trans shop to get shafted by their fine print. We are left owing nearly $400.00 because they pay a lesser shop rate (guess who pays the difference) and they will not cover all the cost of ATF fluids or disposal fees. I will NEVER recommend a Jasper product due to its FAILURE and lack of their personal and warranty integrity

2 years ago we had a Jasper engine installed into our '94 Chevy Blazer over at Diego's Auto Service. Since then we have had to replace it three, yes, 3 times. The first time it died, it was taking in too much oil. This second time, it was leaking coolant into the engine because it had failed. Jasper has not held up their warranty on their end of 3 years/100,000 on this third change out. They are only covering the cost of the engine, not the labor, after they concluded on their end that our upkeep (oil changes/tune-ups) weren't sufficient for them. They aren't giving us any warranty for this newest change out, only our mechanics are for a year. We're still out $1,000.00 for the labor, which shouldn't come out of our pockets to begin with.

I purchased a re-manufactured engine about 2.5 years ago. Freestate Auto Service installed it. Now 2.5 years later, the engine started burning oil, it is still under warranty and it was replaced with another re-manufactured engine. The new engine smoked excessively and I was told that it was the break-in oil burning off, never the less it did not stop, meanwhile the engine light came on and I returned it to Freestate and they stated that it was low on oil.

I contracted Jasper Engines to rebuild an engine for a show truck. I asked for and was told I would receive information about the engine.When the engine arrived, there was absolutely no information about the engine. I repeatedly called and sent e-mails about the missing information and was never given any information other than partial specs. for the camshaft. At 800 miles, the engine blew a head gasket requiring major repairs. This happened while the engine was under warranty. I made the repairs myself as I had also done the installation myself. I called and e-mailed Jasper Engines repeatedly about getting a warranty refund to at least cover the money I spent for parts to repair this problem. None of my phone calls or e-mails were returned.
