Don't argue with Stern, he knows all, tells all, be in awe.

I have seen many times work being done on the timing belt
area/headgasket/or cam and found that the technician never installed the
seal properly, If that isnt the case I would lean more towards the seal is
just hard and worn out, That seal is in there really tight, A PCV valve
being stopped up could not push it out

I want to thank everyone who took time to reply. It looks like the mechanic at
the garage is kinda, sorta correct. BTW he was re-iterating what another
mechanic had already suggested. The other mechanic works on Chrysler products.
He is also the mechanic where I usually get my work done.

I'm also glad to provide fodder for the group. :-)

Sorry about my typo (PVC instead of PCV).
