2000 and 2001 have heads that can crack. But never heard of any Jeep I6 motor with weak head gaskets.

A dealership will charge about 7hrs labor. To pull the head and replace it, not including parts of course.

head is 495 from alabama cylinder head. then you need a head and valve cover gasket. could be around 600-700 after oil change and new plugs. thats if you do the work yourself.

I believe only the 2000 and 2001 have them. I have an 01, and it has it.
