Might be a dumb question but what would it hurt if you ran it to a catch can with no vent? I have a Maryland performance ccv kit it is vented to atmosphere now. I have a mishimoto catch can I am going to install.
I can tell you I had no problems with mine until it ran on Dyno. Ran 2 passes and on the 3rd lifted the heads. Truck is in shop now getting studs done.
