I'm thinking of simply getting rid of the stock setup. I've been using compressor oil separators as catch cans, but it's really counterproductive as the hoses are everywhere.

I'm thinking of replacing the PCV valve with a simple barbed fitting and running the hose from the front valve cover and rear valve cover into a single inlet on a cheap ebay catch can and putting a filter on the outlet.

I figure it's a little more economical than dumping the blow by onto the pavement. I know the ebay catch cans normally do a really bad job of filtering out the oil from the intake on re-entry, but it wouldn't matter if it weren't being directed back into the engine.

Something like this:



Anyone else run the PCV system this way?
