    Wagner Dual Circuit PVC valves

    Wagner Dual Circuit Adjustable PCV valves - anyone used them here in UK yet. They are expensive ($120) but appear to offer full adjustment to vacumn 'suction' at both idle speed and mid/high range just using a vacumn guage. Obvious benefits for 'old clunkers' - wondered about race spec' vehicles too?

    That is a useful addition if playing with cams especially.

    My 'stroker' BBC lump has always built-up a fair bit of crankcase pressure over 5000 rpm (even from being newly built) It seems to be very sensitive to oil level in pan. I have heard also from guys with sbc stroker engines who have experienced similar issues. Whilst there are many PCV valves on the market from various suppliers - non of them actually state the flow rate of them. Accordingly we will buy one for our vehicle not knowing it its really suitable. May be tempted to try one of these out.

    At one time the various muscle cars(I mean true musclecars here) used differing valves and some part numbers are available. Trouble with that is trying to find out at what hg they open/close. We know they are more suited but we don't know the exact details. It proves that the factories put time into it though.

    It's a nice piece of kit by the look of it. I invariably end up binning the PCVs as being more trouble than they are worth ONCE you start changing internal vacuum levels within the engine.
