Reply to "Air/Oil separator for PCV really works"

I'm always amused when there is a "discovery" like this?

Where you been?

In any case, at least you have progressed.

It doesn't seal out oil 100%. I think that is good. You just don't want oil fouling your plugs and you don't want to siphon your oil pan dry through the PCV system which actually is possible.

I was taught, rightly or wrongly, that the oil sucked into the engine was good and necessary to lubricate the upper valve stems.

With the original cast in valve guides that is probably a fact but with the current "bronze" press in guides like used on many of the aluminum aftermarket heads I don't think that is necessary any more?
