    Hey guys, i have a 98 gp and i think i have a bent valve. I think it is my rear cylinder head, so what do i need to repair the head? Does anyone have a thread on about it?

    explain your reasoning on why youd think you have a bent valve. if a valve is bent then a piston or something else hit it, which means something else was wrong first.

    What you think it might be? The car was in good shape its at 198,miles. Its was still runing for awhile until i heard this nosie like a lifter from the rear valve cover. So while its runing i rev it up looking for the nosie. So then it cut off, then i turned it back over, then it just cut off again.

    x1,000,000...don't go buying anything till you rip it apart and see whats going on inside...sounds like what Nick said...I've seen rockers come loose and that'll cause all sorts of cut out issues.
