No, No, the hose that I have the breather on is the one that used to pull air out of the Throttlebody, not the one coming off the intake. I put my hand over the filter and pinched the hose......It, didn't do a damn thing.

That puts air into the throttle body... not out of. Doesn't it?

Pulls air out into the Valve cover via the nipple on the middle of the pass. side one.

I have the catch can running between my pcv valve and intake.

And why is nobody paying attention to the air/oil separator? It is designed to get the oil out!
Are you talking about the home depot air compressor ones? If so, those are for water not oil. It even says it on the packaging.

Depending on the filter medium, and where you read. Some companies call the oil/air, some call them water/air. If the filter is one for oil, it's the correct one. Heck, I'm not a filter medium ologist, but I'll bet that most of them are the exact same with a different label. Oh and the important part: it works, and it works good and it works RIGHT.

I just run beather filters on my LS1.

I have 2 in the back where the stock PCV lines run from, and one in the oil cap. Drilled it myself and stuck a breather in it.

When I had the PCV, I was going through oil pretty quick, and I noticed the TB and intake manifold had a nice coating of oil in them, which I didn't like.

The oil cap breather smokes a little on startup, but besides that I haven't noticed oil coming out of any of the other filters. No smells of oil burning, either.
