First of all, this isn't just another "why is there oil in my air filter?" thread.
I've known about the air filter, PCV valve issues for a while now. After going over the PCV system, replacing all the grommets, tubes, and clearing them of oi, my problem is that it STILL blows oil into the air filter. I know the line is clear of oil because I can feel suction in the line and the grommet going into the valve cover is brand new and free of oil.
I read somewhere that if it is still doing this after fixing the valve cover issues, then I have excessive blowby and my piston rings are shot. Is this true? Could I be missing something?
It seemed like a good idea at the time...
