I have had three 4.0 liter Cherokee's. '89 rolled with 242K. Never had the engine touched. '95 sold to brother, no rocker panels left but 259K. Still running. Never touched engine. My son still has the '01 with 159K. Never touched the engine. Yes all three had a slight drip from the rear main after 130K. So far so good on the '01 head casting. All three were manual trans. Fun vehicles and always ran. Always.
Agree with always running... I'd take my 4 slow Cherokee anytime new york to LA without worrying for a second... In the winter, the engine is warm in minutes, even in less than 10 degrees, never seen an engine that warms up so fast. You may never have an issue with your 01, they fixed it that year and you may have the good cylinder head. Look at the stamped side (driver) on the lower head if you have a 0331 - even the fixed ones still have the same 0331stamp, if you don't, no worries. If you do, just watch the water level for constant drops and oil sludge on the oil cap. Transmission wise, auto aw4 will last forever provided it has always dex3 and good cooling, stock cooler plain sucks. That's the story with Jeeps, ain't yours till you do some sort of mod to it, lol. Btw, for whoever wants to get a Cherokee, 99 is the year to go, it has the good head, and it's the newest year guaranteed to have no head issues.
