Valve Stem Seals

Has anyone ever had a problem with valve stem seals??

I just replaced the exhaust side seals last friday and the OEM replacements are already pushing out and will soon become nothing but little chunks of green.

I never had a problem with them until we took the head off for o-rings, studs and F1 springs. A diesel machine shop went through the head and everything checked out. John at floor-it did the o-rings... now I can't keep the exhaust side seals in.

Yet, the intake side seals are pristine....

What gives??
