Ok well i just got done putting a new pcv valve grommet in and am going to clean out the elbow on top. What would i do to stop the oil from going into the airbox. I would definately like to keep the engine thats in it in there. I was just told it had bad rings because of the oil going into the airbox. I know the head gasket is bad and have to keep driving it with work and school. All the exhaust fell off recently too so its obnoxiously loud and i hear thats bad for the valves. I just hope my motors not to far gone.
