That's where I am already though - with the passenger side tube open to atmo (with a filter on it) and no smell. All I'm proposing that is different to that is a one way check valve to inhibit air entering the crankcase via that tube on snap throttle opening. It will still be able to breathe outwards. And inwards under more moderate vacuum with open throttle.
It's a GM stock PCV valve I intend using and it flows outwards under moderate pressure and only snaps shut under a sudden pressure rise - the equivalent of the sudden vacuum it sees on throttle closing when installed on the driver side. I can't see how the crankcase pressure could rise so quickly not least as under that situation (high blow-by) the driver side PCV valve is open to the inlet manifold. There's been no sign of that so far with the pipe open. The filter on it is bone dry, no sign of oil vapour or anything untoward at all.
Nothing pressurises a crankcase like an explosion in there does. The further I am from that risk, the better.
Oh, derr. I'll have to reread the problem again. It just seems to me that there's a better way to crack this nut. Crankcase vapors need to be purged and this won't allow it. You can't be the only one who's had this issue.
