I put a post on here, a couple days, ago showing the inside of my engine (93 lt1 w/ p600b blower @ 11 psi boost) after running with the supercharger on it for the past 5000 miles.

Theres a little bit of oil getting into the intake manifold. I suspect its coming from the PCV valve. I do have a one-way check valve on it to prevent boost from going through it and pressurizing my crankcase.

What I suspect is happening is Im getting some blow-by during boosted operation. Its getting sucked into the intake (via PCV valve) the instant I left off the gas from boosted operation.

Does anyone have any recommendations on an oil separator that I can plumb into the PCV valve to 'catch' any oil?

I know the LSx guys love PCV 'catch' systems.

 

Just search this forum for 'Catch Can' (search titles only)

Or Google it.

I have used a water seperator like you use on air compressor lines. I found a fairly small one so it wouldn't be to much of a pain to find a place to mount it. I have ran it for years and it works pretty well and is a cheap fix. Just empty it every so often.
