Can someone who owns a Jasper Engine let me know how satisfied you are with it or your dissatisfactions. I am contemplating buying a 302 from them within the next 3 weeks. The price is a little more than other re-builders but I want to buy an engine that will last 100,000 miles with proper maintenance. This is a daily driver to and from work (F150), transmission was rebuilt 11 months ago. I really haven't heard any real negatives about the Jasper Engines but would like to hear from the ones that actually own them and their experiences. Thanks

I worked at a reguler mechaincs shop for a while and at the owners request (and against our advice) they installed Jasper engines a few times. they're usually crap. I WOULD NEVER USE A JASPER ENGINE. With the time and money required to install an engine you may as well use a good product to start with- either a good crate or an engine rebuilt yourself so you know its done right.

I concur with ap72. Jasper (and other production remanufactured engines) are pretty dicey when it comes to quality.

we have installed several jasper running completes, diesel and gas, many transmissions with very few problems. also the 3 year 75000 mile warranty is pretty good. They lways promptly paid any claims we had. whitch as I said were very few.Now this is assuming stock replacement engine, no experience with performance engines from them.

We install Jasper engines all the time $30,000 worth this year alone. We have very little problem with them. Now they are not perfect, and when you do have a problem their warranty can't be beat. A lot of the problems has to do with the install. We do a lot of Jaspers warranty work from other companys and see a lot of crappy installs. Bad carbs, bad distributors, warped intakes, just to name a few. Yes I would buy a Jasper and not think twice.

We put a Jasper in my son's '91 Jeep. Runs great, no problems...Are you looking at a "rebuilt" or "re-manufactured" engine? The rebuilt will be cheaper because any parts that are still within tolerances are re-used, whereas the re-manufactured engine basically uses new internals. At least this is what was explained to me when we got the Jasper...We got the re-manufactured one.

I own a repair shop and have installed many Jasper engines and trans, and just about everyone has had a problem. I replace a trans 5 times in a Chrysler mini van. (All valve body problems) I would get a local guy to rebuild what you have. IMHO the big names are not worth the extra price.

Our shop installs Jasper engines (both gas and diesel) and trannies and find them to be excellent products. Price is ever a determining factor for us, only the wait. That said, I think a "good" loacal engine rebuilder will do you a good job, IF you don't ask for their CHEAPEST rebuild. What I do like about Jasper is they will pay our labor if we do have a problem and not just replace the parts.

All the warranty that I have done for Jasper, they have never, I will say it again, NEVER paid my full shop labor rate. They are 30+ dollars under the labor rate. And fluids don't even get me started...

Maybe your shop rates are HIGH enough!!

[squire]

Our shop is a "closed" shop and only do work on our vechicles and those of employees.

[squire]

Our rates do not have to keep an independent shops doors open so our rates are lower than your average shop.

While some have had good "luck" with Jasper (and other remanufacurers), there are far too many that have had problems. They have a much higher failure rate than what they will ever admit to and, as 1931 steve has alluded to, the "warranty" coverage has it's problems. While it's nice to have a warranty, the idea is to not have to rely on it. With a remanufactured engine, the chances are too great that you will need it.

Also, from a machinist standpoint, the things that I have seen in their heads and blocks are not the type of things I would do to my customers' engines.

I agree with Tom. While we have had "great" luck with Jasper, I always prefer local machine shops and their premium builds. We are on "corporate accounts" and buy if they are available in our time frame. If not we can shop locally.

i've seen the video tours and televised tours of JASPERS and TCI and was more impressed with JASPERS both times and yet TCI seems to get a pretty good rep..still,if it was my money i think its hard to beat GM,FORD or MOPAR,for crate or rebuilt motors.the fewer hands that touch it the better.
