Ok, so many CC threads, I guess this is as good as any. I was under my car today, just to tighten up anything I could reach. Exhaust, IC pipes, intake, etc. So as I was going to tighten the hose fittings on the Mishi CC, I remembered posted that mentioned tightening everything up real good to avoid boost leaks. So the OEM PCV fittings are the "push and snap" type, the same that Mishi supplies with the kit.
Does anyone thing those fittings are airtight? I know that type of fitting is designed to tighten with pressure, but really wondering if they can be that airtight??
