I have a 2008 GMC Yukon xl Denali 6.2. the short version of the problem is i have oil coming from the passenger side valve cover "PCV" port that attaches to the cold air intake. So oil drains into the tube and gets sucked into the intake manifold and then into the engine. I've replaced everything. Didn't do this. Took heads off and put new lifters and push roads and rocker arms and when i put the head back together and the problem started. Just took the heads off again and put it back together and still same issue. If i cap that hose no oil comes out into the intake. I don't know that to do.
