I installed a crappy chinese oil catch can between my PCV valve and intake manifold, which worked for awhile but eventually the bottom of the OCC blew off. I'm assuming this happened because I never put a check valve between the OCC and the manifold and the constant switching from boost to vacuum wore it out. So, I've been looking at different setups for boosted cars and I've seen cans with 2 exit ports, one for the intake manifold and one for the intake. This way there's always vacuum applied to the OCC, which got me wondering... why not block off the intake manifold altogether, tee the breather and pcv valve together, and use the intake for constant vacuum? This way there is always vacuum on the PCV valve and the breather will have the same vacuum it would have normally. Thoughts?
