open the PCV valve and clean out the pipe. replace the valve. then take out
the EGR valve, you will find the hole where it mounts clogged with carbon.
that clog is pressurizing the crankcase and causing oil to go through the
engine. Just get it to breath properly, and the thing will run better, and
even get better milage. It takes a good mechanic to find these little
things, but they are easy to replace or repair.
