83 CJ7 4.2L

I'm on #1 cylinder and I have a valve that has a rim or lip at the top of
the stem where I can get the seal only partially down. I can't get past
where the keepers sit and down onto the stem. What's up with this? What
can I do in this situation? The last three valves have been ok. This is
the first with the problem.

Thanks for any suggestions.

Bill

 

Should I protect the area from filings and take a file and file the lip off?

Thanks,

Bill

Bill, that sounds like the top of the valve has been pounded flat?

If so, then you have issues with that rocker arm for sure and likely the
push rod and/or the hydraulic lifter for that valve.

Was it physically loose before you unbolted it? Was the nut loose that
torques it on?

Have you had a bad tapping noise at idle in the past that 'maybe' went
away?

Are you the guy that had the 'timing ping' at idle? If so you just
found it.
