Default Bad News After Head Gasket

Well, with my 1996 XJ back together after the head gasket replacement, it seems that I have 0 compression in #4 and 60psi in #6.

Looks like its time for a new motor!!

Any ideas on what year engine would be best for replacement??

did you do a leak down to see where the compression is going first?

its unusual for a cylinder to have Zero compression you must have a stuck/poorly sealing valve.
