So i have a ek d16y4, it has a turbo and is running 14psi.. car has no internal mods, it has a very good tune and has been fine for the last 5000k... however there is oil coming from the crankcase ventilation filter..... some ppl just say its normal throw a catch can on it, however obviously something causes this and i would like to fix it does anyone no what the problem mite be??? thanks
Maybe your PCV valve is blocked?
I'd have a check through the whold PCV system.
Being turbo, how is your PCV system operating. If you valve is bad. You could be leaking boost through the system via the intake manifold and out the rocker vent. Hence your oil issue.

Install a catch can, 14psi on stock internal :O. Any Dyno sheet
its just a little k&n filter in the valve cover.... i havent checked the pcv valve but that was the plan today... and the oil only really comes out under load or boost so wat your saying would make sense... thanks ill go check it out.... PS cheers for the diagram........
