Check valve wasn't closing properly. It had a rough movement. We have another one coming just for backup.

Even with the repaired check valve we are still blowing the oil on part load driving. We could not determine any leaks thoughout the PCV system. I didn't ask if my guy smoke tested it but he says it's right now. What's strange is under full hauling ass driving there is almost no oil coming out. I really notice it on highway driving cruising 2200/3000 rpm when the boost comes in and out. This made us believe this was PCV related. You may be right about the repair fixed a small vacuum leak. The catch can sure as hell fixes the oil issue. Check valve was installed correctly originally so it wasn't backards. What I'm curious if the spring is weakened more will it bring on boost quicker?

I can only hope there is no other underlying issue. It sure drives great now so who knows.

** note to googlers. Must add catch can to Moroso 84565 search unless your into Asian porn.

Pickles, Dan caught this before you when I was telling him about the mod. LOl
