Need New Engine

I just got my 1984 Jeep C7J in December 2012. Unfortunately I have had nothing but challenges since I got it. Anyone have advice for me as far as who to purchase a new engine from?

That's tough because there are so many considerations. Cost, performance, warranty. I have a local friend I would probably trust to rebuild one for me if needed and I would rather deal with him than someone across the country over the phone. With that being said I have put a Jasper motor in one of my Mustangs years ago. The mechanic was a Jasper dealer and I believe that is the only way you can order a Jasper motor. It was top notch and never missed a beat. It wasn't much more than the no name reman companies out there either. One of my friends that bought that mustang is still driving it today and that was over 10 years ago. If I ever go that route again it will most likely be through them. Good luck with it and sorry for your troubles.

I've heard good things about S&J Engines.

how bad is your engine?

IMO, if your engine is a good rebuildable core you are better off finding a reputable "machine shop" to totally rework it. is it the original block that came with the jeep?, do the #s match?. if so rebuild it. if not than weigh your options and go with one of the recommended builders that have a history on the forum. avoid auto repair shops, they would be a middle man, they have to send everything out for machining and are to risky.

I bought a engine from a jeep specialist in York PA back around 1999 or so. It lasted 15,000 then started making noise. When I took it apart a first time rebuilder could have done a better job.

I took it to my engine guy and he did a awesome job. It purrs at idle.

First thing he shown me when I dropped it of was a bent crank. Even had me feel the tight spot.

another vote for S&J. 7 year 100k warrenty. Great price nice people. I boogered a headbolt and they sent me one. No charge. My engine has 4 or 5 k on it since the rebuild. passed calif smog. doesnt lose oil. came with all the gaskets.
