Default Any adverse effect of taking the PCV out and capping the PCV nipple?
Basically venting it to the atmosphere with some sort of home made catch can on the end.

I noticed a little oil in there. I know small amounts are normal, but I am curious just how much oil gets vented back into the intake.

So I want to run with a PCV out for a while with a short hose pointing into some container.

Is that ok? Will absense of a vacuum on the other side mess things up?
