I think that when your blower is working hard it causes a vacuum in the inlet tract and oily air is sucked down the breather hose from the head. I had the same problem and thought I should put a catch can between the head breather and the inlet pipe. Didn't get around to it before I went turbo but as a have similar plumbing for the turbo I plan to do it the same way.



The reason the red breather pipe is so long is that it is temporary until I mount the catch can and those silicone hoses cost heaps so I'm not going to cut it until I know the correct length.

 

Here's another thought. Your PCV is a one way valve. When you intake is in vacuum (throttle closed) the PCV allows it to suck air from the valve cover and hence burn oily vapour. When your manifold is in boost (WOT, high revs) the valve should be closed (as it's one way). If it is failing and letting boost through it would pressure the valve cover and this pressure would escape through the breather. So not only would the compressor be sucking but the manifold is blowing past your PCV. Oil city!

Anyone know the conclusive way to test a PCV? Do you just blow one side and then the other? What sort of pressure should it hold? It's designed for NA and we're boosting so perhaps we are exceeding it's spec.

 

I just found out what was wrong. I called paxton and they told me its my bearings and seals so they are gonna replace them .

 

was it covered under warranty and why not send it back to comptech?
