Lew:
Goo on all the pistons or just the one?
Did you do a compression check before the piston was pulled, wet and dry?
Over fill the air cleaner?
Stock air cleaner with the valve cover breather pipe hooked up?
Is the washer still in the air cleaner breather?
It almost sounds like you've got a crack between the combustion chamber and a
oil passage that opens up as the engine warms up if the problem is only in one
cylinder.
If it is all cylinders, then the oil is coming through the intakes. Check the
draft tube by the transmission and make sure it is clear. If it were pluged,
all blowby gasses would have to go out the breather on the valve cover, and that
much vapor would bring along alot of oil. The valve cover port can't block the
oil with that much blowby passing through it. Perhaps a piece of the side cover
gasket is stuck over the draft tube outlet or the gasket was flexible enough
and has just pushed itself against the draft tube outlet as the the engine warms
up and develops more blow by. The gasket could be "oil canning" against the
draft tube outlet.
