I Need a parts list of what we replace on the PCV system on the AWM engine...

I tried searching this, but I'm either not using the correct criteria or I find stuff for other engine codes. Can somebody give me the 411 on exactly what I need for 1.8T AWM engine? I'm getting a little seepage of oil around the valve cover and I'm beginning to think that maybe the PCV is the culprit.

My B5.5 is a 2003 model, 1.8T engine, 55,000 mostly suburban miles. All oil changes with 502.00 spec or better oil. A schematic would be helpful, too!

Okay, I got the ETKA page - what do I need to buy?

#5 and 6 (or 6A depending on your car) in the diagram plus the clamps. Buy screw clamps as the 1 time use clamps are almost impossible to tighten once on the car. #2 can break easily, so watch out when you pull it apart.
Hey, thanks for the info! Can you give me an idea what size clamps I will need? I'd like to start ordering the stuff and getting it all together to attack this job.

The puck in the back of the engine should be okay?
That doesn't match my AWM engine. The puck is on the intake hose (not the back of the engine) and there's no purge valve (058) in the diagram, which I understand is a prime suspect for the leaky valve cover.
I know that the puck on my is located at the rear end of the block, between teh engine and the firewall. I'm not sure if it's connected like this diagram, though. I haven't been under the hood since it is below freezing with a wind chill in the teens at the moment.

And that purge valve - where is that? Can anyone lead me to the correct ETKA page for that?
Also check out EKTA 133-25 for the "suction pump." That was plugged on mine. I replaced those other items too, but the suction pump was really the only bad one. It, and the PCV "bleeder" valve (6,6a) seem to be hooked up differently than in my 2001 AUG engine. It is the angled branch of the "Y" which is most likely to plug. If you unhook the hose from that, and can feel suction when the engine is running, the suction pump is probably okay.
Thanks for that add'l info! I'll have to add that to the list.
