The clear hose is an excellent idea for checking the baffle in the cover.

I also had the same problem with #2 on my most recent engine. PCV on a qjet is in the front and even though it's centered and supposed to feed the entire plenum, it somehow feeds most of the oil into #2 cylinder. I was sucking about a quart every 300 miles!! I have tall Proform covers with what I thought was a pretty good baffle. Not quite true. What I ended up doing was very simple and fixed the problem almost 100%. I put two 0-rings around the PCV valve to space it up from the bottom of the baffle. Mine was sitting ON the baffle and sucking any oil that came it's way.

I also have an oil separator in my PCV hose. It helps but did NOT trap all the oil that was going through it. Maybe it's kinda hoky but it now has over 1/2 quart in it that was filtered out of the PCV line from just normal blow by.
