blueracer Posted March 15, 2013 Report Share Posted March 15, 2013 Is your PCV valve plugged up or do you even have one? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted March 15, 2013 Report Share Posted March 15, 2013 Too much crankcase pressure. Get a catch can that will allow the motor to breath and vent out the pressure. Moroso makes a nice one with a filter for this purpose. Jegs has it.... The stock PCV system suck anyway..... I didnt have your exact problem but I had problems with blowing oil out of the filter on my valve cover and soaking the passenger side of the motor. Got the catch can with filter and no more crankcase pressure issue. Quote Link to comment Share on other sites More sharing options...
