Hi guys,

After learning a lot from rebuilding my 272, I am in need of some more forum advice... please of course!!

I have ran the engine for a total of about 60mins since rebuild. I pulled the plugs and am finding a wet thin layer of oil on top of the pistons. Is this normal?

My thoughts are-

1) Rings are still seating?
2) my pcv valve is sucking oil due to a poorly designed baffle (my bad) and I suspect it's accumulating on top of the pistons and plugs are dry.

There is no smoke from the headers while running.

Under normal operating conditions, what should the top of a piston look/feel like once the plug has been pulled.







Thanks, Dennis.
