Greetings and thank you everyone for reply!
I ran into a problem, I had open breathers for over a year but the smell of fuel became unbearable and I decided to go with recirculating (non vented) catch cans to "close the loop and make it factory like" and thus eliminate smell.
Setting up like in example photos from catch can manufacturer I get severe smoking from exhaust like a chimney with intake breathers connected from crankcase to intakes as in photo but without baffles. Also within seconds had about half cup full of oil in both of my catch cans.
Setting up with closed off intake and manifold breathers it doesn't smoke but I am very fearful of pushing the car because I have done something wrong with tubing from/to catch cans.
Please help me out guys, thank you.
