This makes me wonder about something:
What is a normal level of "pressurization" within the valve cover? Mine, for
instance, gives out a "poof" of pressure if I take the oil fill cap off
while the engine is idling. It's not huffing out smoke or anything, but
obviously is maintaining a bit of pressure in the cover while running. Is
that normal? Should the blow pipe to the air cleaner release ANY/ALL
pressure in the cover?
There is some very, very minor oil leakage around one of the two hold-down
nuts on top of the cover, but I think that likely attributable to my
forgetting to goop it up with sealant last time...
