crankcase blow-by

How dit you evacuate any blow-by in the crankcase ?
I am using the stock pvc valve and 1 hose to the inlet side of the supercharger, just like Paxton prescribed.
Recendley I found out that at full boost I have some blow-by, and therefore some gaskets starting to leak a little oil.
My engine is a stock bottomend and has seen 120k miles so it is ok it has some blow-by.
Also I tested a old and new pvc valve with a airgun and found out that they are both "leaking" air when you blow in to it trough the hose:eek: so under boost these things do not close a 100% !!
So now I am going to use a crankcase evacuation system connected to the exhaust right after the O2 sensor.

I have done a Google search and found out that they do work on mufflered cars as long it has alot of flow.
I have headers and flowmaster 40 series that ends before the rearaxle so enough flow.
What are your thoughts ?

Save time and money and just get a PCV from a 94-97 TwinTurbo Supra to replace your stock unit.

u can also get a oneway check valve from a brake booster off a older car

That's a good tip, why dident I think of that before ?

I just run breather caps on both sides of the engine, on a V8. PCV dont do a whole lot at WOT because vacumm is at zero. But with 120k on engine you may have some ring seal or valve guide issues. If all else fails , then do a leak down test on your engine.

It is more important to run a PCV when you have Positive Boost(Supercharged).
The PCV will close from the pressure and restrict the motor from sucking oil into the motor.

I may try that.
