Well, the point was ade to me about the catch can that if you hook the catch can up with a line to the intake (pre-turbo) you can actually create a vacuum in the crankcase. It may not sound advantagous, but if your oil is backing up in the return line to the pan (like I believe mine is), then it will help out a lot. I am also working my way down through restrictor size for the oil feed to lower the flow some. I am down from the -4AN original diameter of .175" to .110" and I will soon be going down to a .063" restrictor as the .110" doesn't seem to be quite enough. I may try .093" first, but I really don't think that it'll be that big of a difference.
