[QUOTE="Hangman, post: 11418389, member: 98903"] Did you remove the ball that acts as a pressure fitting for that PCV valve, if you drilled it out, try opening it up some more to allow some more breathing room. Otherwise it looks like it is plumbed correctly. I had an issue where i blew my valve cover gasket on the passenger side because there was to much manifold pressure. Try and open up that fitting and take it for another drive, also, take it for a gentle cruise and check it, then go more a spirited cruise, you dont have to go WOT but get on it and see if oil starts to seep through. This will tell you that you have restricted ventilation and have high manifold pressure. That breather is the weakest link and oil is finding its way through, if it gets worse or if you just make the seal tighter on the breather, the oil will find another path, most likely your valve cover gasket where the RTV meets with the block and the front timing chain cover, then next would be the gasket that surrounds the spark plugs between your valve cover and cylinder head. This is what happened to me. I fixed my issue by making sure there was enough "breathing" room for my motor. Double check and check again. Not saying i am an expert, just going by personal experience, GL. [/QUOTE]
