Car, engine, year? My guess would be worn piston rings and/or valve seals or guidelines.

It's 13 years old and 200K. Although engines usually last longer than that these days, that's still quite a few miles and under what conditions? 200K with a K&N filter, it would not surprise me at all that the rings, pistons, and bores would be shot.

wear & tear.

Most common issues of this symptom are:

Piston rings going bad, badly worn cylinder walls, valve stem guides, or badly worn valve stem seals, also if the PCV system is bad. clogged or inoperative. This could cause pressure to build up in the engine causing the leak as well.

I have a similar issue with my 2000 1.8 160k mile Beetle. I just changed the spark plugs and the chambers where the coils are sitting in were totally soaked with oil. The thing is that the spark plug tips were perfect and no oil fouling on the electrodes or ceramic tip at all. Also the car does not burn any oil between changes. So where could this oil be coming from? How do I check the PVC system? I am sure it is pretty old and needs replacing but I don't know where to look and what to replace. Overall the car runs GREAT and there is no hesitation or lack of power so I think my compression is up to par. Thank for any help and or suggestions.

Do a compression check. My '98 is 7,000 miles short of 300,000 and runs great. I might be a faulty head gasket.
