I own a 2007 Cobalt ss/sc and I seem to be building up crankcase pressure and it pushing oil out mu dipstick tube. I know it dosnt have a pcv Valve but what other valve is there that I could check? or what else do I have to look at?
There is no PCV valve. But it does sound like you have a blockage. If you are handy enough, you will need to remove the intake manifold and valve cover and clean them. Better yet is to drop them off at a local machine shop for a hot tank. Usually $30. Either way, the key is opening up the orifice on intake manifold. Its in the center, between ports 2 and 3. Very small, so easily clogged
