http://www.blauparts.com/vw/vw_oil_l...il_leaks.shtml address's those issues i think
My car has a bit over 100k on it. The original ownwer did little to maintain the car. I pulled the plugs and found oil all over the sides of them and some of the threads. NONE on the spark end and after looking down at the top of the piston the pistons look dry and oil free. Is this a sign of failing vavle cover gaskets, cloged PCV hose or valve?
I installed brand new plugs and on the up side the engine runs alot smoother. not to fix this oil prob and exhuast leek and it should be quite and smooth again.
The Prime Culprit:
IF you don't do a thorough and COMPLETE PCV OVERHAUL along with buying the 3 yr old Pressure
Relief Oil Cap you will find yourself doing this more often - especially when you live in climates
with wide daily temperature swings coupled with short drives.
The "NEW" PRESSURE RELIEF Valve that's been on the market the last 3 yrs does HELP which
can be bought either at the dealer or even aftermkt distributors like ECS Tuning.
BUT one really needs to do a COMPLETE PCV Overhaul given the mileage and conditions
experienced on a B5 and B5.5 series (the latter was redesigned and appears to be less prone
to clogging than the B5's).
Yours is a B5 with the dreaded Suction "Y" Pump that consistently gets clogged requiring

They are just a rubber diaphragm rather then a suction valve, I replaced mine ($112 from the dealer!!!)
The new style pressure relief oil cap helps to fix the issue of sticking pcv valves on the 2.8/2.7/4.2 engines. I would recommend replacing it with the valve covers and CCT gasket ktis.
the car is on an inclined driveway and up on jack stands in the front onlyMaster L1 ASE certifiedVW's don't leak oil, they just mark their territory!
