If this is the case, get it fixed sooner than later. Pumping a lot of dirty oil through the intake will cause you some big problems if you let it continue.
You will end up with valve deposits and a ruined CAT.
At 80K miles, you shouldn't have ring or valve guide problems unless the oil wasn't changed as specified on a regular basis. If it turns out to be something major like rings or valve guides, trade it in, it isn't worth the problems that you are going to have if the engine is worn out b/c of neglect.
If someone neglected the engine to the point that it is worn out now, the transmission and the rest of the drivetrain is probably junk too.

neon_rt,
You brought up a point that I never thought of. In either case since he's well past the 60,000 mile service I'd think it would have been changed at that time. In my book to have the PCV valve go bad is not commom although anything is possible. At this time in the mileage game they don't cost much to change but again if it doesn't work you know at least you have elimated that possible part. Get it to a good mechanic to better yet the dealership.
