Default Turbo Engine Back Pressure

I have a turbo system on my ITR and runing stock internals on 7 psi boost which is the limit allowed. My problem is I see oil coming out of the breather filter on my valvle cover. I checked my PCV valve its ok the lines are not clogged but the vacuum box at the back of the engine was half full of oil which should have none at all. Anyone have any ideas or solution?

Is your PVC still connected to the intake manifold?

You need better crankcase ventilation. I have the T1 catch can kit a bit expensive but worth it.

At 7 psi that should not be happening. You need to do a leak down test. Not a compression test.

Hit us back with the % leak down you have.
