Ok, not sure if I have completely misunderstood PCV....
On my 3sfe I have a connection from the valve cover to the manifold.
Now, under vacuum this sucks the air out of the crankcase into the manifold to be burnt up again, yes?
So I have a one way valve on this so under boost conditions, as the manifold is positive, it stops pressurising the crankcase.
And I also have a breather tube, from again the valve cover, that connects to the air box. This now connects to the cone filter piping before the turbo.
Now..I have an oil catch can, but I have put this on the breather tube.
That doesn't sound right reading what I have written, shouldn't it be put between the valve cover and manifold ?
The breather tube....under vacuum it pushes out air. so connected to pre throttle, that is just going to increase the amount of "suction" and pull more air out of the crankcase. So in boost situations this is now pulling out air and stopping over pressurisation.
So reading THAT, I should out the catch can here.
Ugghhh.
What I am being to dense to understand here! 2 catch cans ? Breather just out to a mini filter ?
Breather supplies fresh air which is then sucked out by the manifold valve...if so why does it puff out air when idling rather than drawing air in?
someone put me out of my misery. It all works, but my catch can is arse-about-face?
