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.
