Hal, I looked into that when he was here. Oil is definitely going
somewhere. The Paterson block offs and thin gaskets were poorly positioned
and I fixed that. It is not leaking out of the ends of the China walls. No
visible smoke out the tailpipe. No filter or oil line or cooler leaks.
Engine hits evenly on all cylinders. Roller cam and roller rockers,
mondello oil restrictors. I don't know what valve springs and retainers or
oil seals were used on the valves. That is what I suspect. Large clearances
between stems and guides accompanied by poor oil seals. Engine burned the
tires going out of my driveway, and has very good power, so I don't suspect
pistons and rings. Runs quiet.

Didn't know you had been looking for an issue Jim. Might be something as simple as non stock valve covers with the incorrect baffles? PCV valve issue? Your seals' guess is probably a good one, good place to start.
