how is the proper way to make a good breather system for a cosworth engine. Right now the oil is keep coming to the the oil separotor and after a few runs ( 1/4 mile) I have to drain it and add oil to the engine. Anyone got a drawing? Right now I got the spec R sytem!!!

I run the 3 port system on my car with no hassles.

 

Thanks mate, but the spec R system is exactly the same and I got the problem I mentioned ( only on 30psi boost) a week ago i was reading a topic somwhere here and a guy named Tony of Turbosystems said something about like these systems are like having a 3 inch exhaust with a 1inch tail pipe! I need to find that post!
