If it's the smoke is blue, I'll wager credits to navy beans that the valve guides are on the loose side.
On fresh "race" engines "one" can run without valve seals. It is really the amount of clearance that the valves have that cause the oiling down situation.
The guides tend to rear thier "pretty heads" when you start a cold engine.
The rebuilder didn't say anything about knurling the guides did he?
Even the threaded in replacement guides seap a lot of oil because of the spiral grooves that are left.
The only good guide is a new one.
I hope that the answe is something small and stupid that everyone is overlooking.
Doug,
I haven't spoken to Russ yet about the valve guides though the paper work indicates new bronze valve guides were installed. I think the following is a long shot for solving the problem but I do have a problem with my fuel pump. I believe it is leaking oil from where the pin that supports the arm passes thru the housing. Who knows, maybe some oil is also making its way past the diaphragm? I guess I might as well solve the oil leak problem with the fuel pump and see if it helps any with the oil burning.
Thanks,
Art
