in response to the PCV question.
I agree that it can be retained,,,,,but if your setup needs lots of vent then you may as well ditch the valve. On a boosted app , god forbid the valve does not blow shut..in any case your not likely to have enough vent to a can with a small hose from the PCV location
I have had poor results using small hoses, I run a check valve to the can with a small 1/8 orifice to pull vapors any time there is vacuum. that keeps things cleaner.
the last couple I have installed I ditch the PCV and run a can with as many vents as practical , then tune out the un metered air that the PCV allowed.
On boosted I run a check valve to the car system vacuum to prevent losing the brakes and AC controls, had to install an electric vac pump on one supercharged car with a big cam...No vac
By the way the PCV system will absolutely crap up an intake.
