New forum member here. I've owned 2 YJ's in the past (both 4.2's) and just picked up a 1994 4.0 5 speed Wrangler. Well, the "misfire" in the motor turned out to be a bunch of collapsed lifters due to a suspect oil pump.
Instead of rebuilding it seems like the best course of action is to find another running Jeep to scavenge the motor from. I am thinking a 4.0 Cherokee or Grand Cherokee is the way to go.
What year motors can I use for this? I want to do a direct swap without headaches. I do not want to get any sort of odd ball or performance upgrade; I just want to get plug and play and get back on the road for the summer.
I assume the latest motor I can get is a 1995? Is that correct? What is the earliest 4.0 motor I can go with? Anything to watch out for on certain years?
1988 - 1995, or should I look for a 1991 and up?
Also, does it make a difference what transmission is in the donor vehicle in terms of plopping it into my Wrangler?
