Coolant, up in Ohio

 

Ok, if its goin in cyls, wouldnt that cause a performance issue, he says it runs good, but maybe its not firing on all 6 (just guessin here until I can do a plug check on it, havent even looked at it yet)

 

And here you are wrong.
FIRST MAKE SURE IT'S COMING FROM THE HEAD. Then if it is, remove the head and check for cracks. If there's no cracks visible, send it to a shop to be cleaned and checked and have the valve stem seals changed. Go buy a $70 gasket set and change it yourself... Done.

If it IS cracked, got to a junkyard and look for a good one, repeat above process..
Don't sell your jeep because a head

 

It will still run but not to optimal performance. And if the heads cracked it can cause stalling, etc...

 

I was losing coolant, removed the head on my jeep, it was cracked, bought a jeep on CL for $200, took the head off that one and resold it for $350. Seriously doubt youll be that lucky but that's what I did. Also I didn't have it cleaned or checked or have the valve stem seals replaced. Which is stupid, but I was broke

 

what yrs interchange on these puppys, will pickup serv manual if he decides to go that route if thats what it is. And thanks to every1 for your input, its much appreciated, Im a double amputee due to gettin side swiped on a bike and thats what i work on is v-twins to keep me sane and I can still turn a damn good wrench...not to get off subject

 

Not exactly sure, I did a 95 to a 99. Ask around

All good points, sir. But we can't assume that the OP or his cousin has the mechanical aptitude to do what you did.

Most folks will have to pay to have this done. They have already taken it to a shop to have it looked at.

If the coolant has gotten into the oil, the bearings could be on their way out depending on the severity and time it has been mixing.

It makes absolutely no sense to put a known flawed 0331 head back on, remaned, junkyard find, whatever. Remanning will not fix the casting flaw.

Sometimes pouring $1,000 to $3,000 into a 13 year old vehicle is just not economically feasible or the best use of one's money.

 

Good catch.

This thread is by far the most comprehensive one online for educating yourself about the infamous 0331 cylinder head.

Required reading for anyone with a 2000 or 2001 XJ.
