I've had this problem for a while. I have oil coming back up through the crankcase breather hose and filter; and falls into the air filter box. Then some of it gets sucked into the air filter clogging it. I lose about a quart everytime I do an oil change, every 3000 miles. One guy told me to change the pcv valve and it should stop it. Well I've changed it and it still comes up. I'm hoping it's not something internal! Can someone help me OUT?
