I looked everywhere on this forum for a diagram of diff configs for catch cans. Im having blowby issues and want to try some diff ways. Im running a greddy catch can and it has never had a drop of oil in it. The cars seems to burn the rest.

And someone posted this:
Are you wanting to run a vacuum pump based catch can or a recirculation based catch can. You'll need a pair of check valves and to tap into the intake manifold (assume this is where the stock PCV system connects to) with a one way so it doesn't boost into the crank, and put the other one way going into one of (or both) of the pre-turbo pipes. Those two act as your "vacuum source", connect them to a "T" and the output of the T goes to your catch can, which then pulls from the crankcase breather.

I made one out of an air/oil separator meant for an air compressor that I bought from Lowes.....took about 20 mins. It catches oil........I too have some blow bye issues. The only thing is you have to plug up the lower nipple deal because it can't hold the pressure for some reason.

Edit: One thing though is this set-up only holds about 1/4-1/5 the volume of the greddy......so you have to check it more regularly.
