I was a passenger last weekend during a 2002 Liberty engine fail. 188k miles. started hearing tapping noises going uphill pulling a boat. owner said "it's a heat shield". sure didn't sound like it. he said it made noise "on the trip up". within a few miles I surmised that we were not going to make it to our destination. the noise got louder and more constant; then it stopped completely. pulled over. smoke everywhere. oil everywhere on the right side of the engine compartment. dipstick showed about 1 quart overfilled; coolant reservoir was low; oil smelled a little odd.

apparently a rod wanted out of the engine. I'm thinking that maybe some coolant was mixing into the oil, contributing to bearing wear.
amsoil for the first 80k of its life; dino after that.

Owner just ordered a Jasper replacement engine.

Looks like the replacement will only last about 15k miles. grin

With the over filled oil and low coolant, my guess is a head gasket failure. The Jeep 4.0's that had the head cracking problem would usually fail the same way. It would overheat, cylinder head would crack, coolant would get in the oil, and before long the bearings were shot and the oil pressure would get low at hot idle. A few months later and a rod would come through the block.

It was 12K short of 200K that a pretty good life for a jeep engine. replace or get it rebuilt and call it good.

You know I was really tempted to say that too.
Then you could buy the factory diesel badging for a liberty and show your diesel pride.

A sample of one means nothing. Stinks to be the guy with the bad engine but 1 data point isn't a valid way to make a decision.

I'd pass on the Jasper engine. There are better choices, some of which might cost more but IMO if the vehicle is still good would be well worth it.

02s did have that issue, more so than the 03+ 3.7s. I'd bet money he wasn't running HOAT coolant too.

Pretty common to see well over 200k+ from newer ones, or even 300k.
