When the car is running , this ball is irrelvant.

This problem is driving me crazy as that oil is pushing past the seals in the turbo and causing the worst smoke i have ever seen from any car. It is like that arcade game Spy Hunter where you are trying to get away from the gangster types and you have a smoke screen button. I am absolutely blinding everyone behind me. Anyways, I am sure it is either the seals in the turbo that are blown or the oil return pump is not functioning as it should.

I am leaning more towards the turbo return pump as the turbo is relatively new (less than 5k miles). My question is about the return pump. Do these fail? What parts are rebuildable? All I have found are the gaskets/seals but I dont see these as a major issue that would cause pump failure.

Any help is greatly appreciated as this is driving me crazy

I left that Ball out and it immediately looked like I was fogging the ENTIRE freakin neighborhood for Mosquito's. The ball does not restrict pressure, it is a flow restrictor, and it is incredible how much oil will flow past your seals and flood your entire intake system without it in place. I left it out on a brand new HF2 and freak'd out. Put it in and problem was immediately gone. That ball is a goofy way of doing things, but it serves it's purpose. And it works when the pressure hits it and blows it up into the banjo and partially blocks the holes in the fitting thus restricting flow. The neighbors showed up in my garage to see what was on freakin' fire man!
