Directly underneath the exhaust manifold. On the center of that side of the block. If you are looking at it from the drivers fender it's exactly in the center. I don't know the series #'s but I'm sure you could find 'em here somewhere.
"Nitrous? So is that like viagra for your Jeep?" -mom
So will all 4.0's from any jeep vehicle be compatible with each other as long as they share the same casting number?..
I just looked on a rebuilt engine place and my engine was made in '91.. but my xj is a '92... and those years have different pilot hole lengths? will that make the tranny incompatible with the new one?
I guess I just need to know what year engines from which jeep vehicles are compatible with my '91 engine, but called a '92....
P.S. the engine has never been replaced.. and it is a HO version.. its just that my jeep was put together in '91 and sold as a '92.
I don't have the bearing info on the top of my head as far as interchangeability. Try :http://www.jeep4.0performance.4mg.com/
and look around. Dino would probably be able to help if its not on his website. I know he posted it on another Jeep board. 91-95 should be the same engine. Some differences in electronics/emmissions. You could also try NAPA and have them cross refference the bearing. If its the same part # for the years, then they'll match. Also, Advance Adapters makes some for adapting. I know there's one series of 4.0L swap that they have the only bearing for it. Its around $20. Not bad for a specialty part.
