rev3

[s. jones]

my rev3 turbo has started to throw lots of oil out of the catch can which I have venting to the air, my first thought was piston rings but a compression test shows all cylinders to be within 2psi of each other, the car still pulls well without any smoke and all turbo/inlet hoses are completely dry from oil, anybody any idea what could be causing this problem

1) What are the compression test results? (ie. The cylinders are consistent, but could they be consistently low?)
2) Is is the stock catch can? If is isn't, does it need emptying? If it is, might the drain back to the sump be blocked?

It is the stock catch can, the drain is not blocked, the compression results are where they should be

Might be worth changing the PCV valve to see if that helps, they're not too expensive
