Ok guys I haven't been on in a while since someone pulled out in front of me and totaled out my xj well now I am looking at a new one and the head gasket is blown he just noticed it was over heating and when he went thru it he found that there was oil water mixture. I offered him $1500 for it and its an 01 with 120*** on the motor is it easy to replace the gasket

 

It's not just the gasket. It's also not easy.

It very well could have bearing damage. And/or a cracked head.

To be on the safe side, figure on spending $2500+ depending on what you can do yourself to make it reliable again.

 

thats 2500 with the vechial purchase?

 

Have u heard it run? Could also been a blown motor like mine.

 

still starts runs and drives

 

op, how long has the guy know that it has a blown head gasket, and how long did he keep on driving it?

i disagree with it being a hard job, it really isnt if you do it right and its simple

 

Mine still ran and drove too without a #5 piston granted not very well but still ran

 

$2500 in parts and labor after the vehicle cost, depending.

If you do decide to get it and later come out cheaper, and still fix it right, that's good.

And I disagree with you, because as I said earlier, it depends on how much he can do on his own. Not everyone has the same mechanical aptitude.

It has the 0331 head and the original owner has driven it apparently a fair amount before coolant was discovered in the oil.

 

That's the key there. Bearing damage from the coolant might not appear until after you've replaced the gasket and forgotten about it.
It's not unusual for bearings to fail shortly after someone repairs the top half of a motor, which they commonly blame on "all that new power", lol.
That isn't why...

 

Exactly. All too often people worry about just the head when it is the whole engine.

Then they spend at least double money and time going back into it again.

 

I'm gonna agree with Firestorm,

This is an '01, and anything late 99-01 had that flawed 0331 Cylinder head (with the exception of the TUPY head, but Idk if the XJ came with the TUPY). If the seller is so clueless that he just now realized that it is overheating and has coolant in the oil, I'd either run from this rig or buy it REALLY cheap considering you're likely gonna need at the least a new cylinder head. Here's another big deal maker/breaker: what's the oil pressure reading? Wouldn't surprise me if the coolant hasn't already started wiping out the bearings.
