Alright...

I've got my catch can setup almost complete...running an Endyn modded Moroso catch can to 2 different places on the firewall side of the block to elimnate excessive crankcase pressure. Positive crankcase pressure will flow via (2) 1/2" hoses into the catch can and then routed back to the intake manifold running through a PCV valve (closed loop).

Here's the question...What to do with the famous valve cover breather port? Where should I route it? It's supposed to have positive pressure on it, correct? (so that air would flow into it, not out of it???).

Any suggestions please...I know this topic has been beaten to death, but?

Thanks. Tom

just use a filter....the intake manifold will suck the air in. you dont want it to be pushed in.

I though we shouldn't use a filter?!

Now I'm confused...

The filter is to vent the excess pressure, while the catch can is taking oil vapor out of the intake charge. For a closed loop setup have the tube slashed facing the incoming air.

Oh man, I am not typing that entire explaination again.

Baically:

For FI put the filter on unless you can use a cut tube in front of the compressor intake with the proper angle cut in it.

The search has the long-winded explaination.
