so i installed a catch to the valve cover awhile back and never noticed anything in it. Well after a drifting event were my wastegate went out and i was running 20 psi on a gt2871r, that has now be fixed. Whenever i get into boost it seems that some of the oil in the head will go straight for the T fitting on the valve cover and into the catch can. After a few minutes of some what hard driving the catch can will be half way full.

Any suggestions on what is happening or what i need to do

cliff (catch can filling with oil when hitting boost)
