I did the valve stem seals a couple year ago. They were rock hard! Then I replaced the intake gasket which was leaking like a sieve. That helped cut down on the plug fouling, but I still have consumption and now running hotter plugs to burn off the oil. Must be oil control rings. Compression test was done at the same time and all cylinders were about 150 and within a few psi of each other.
Speaking of valve seals. Blew the valve seals on a 318 by overfilling the oil.
