Thanks for the help. Thankfully my dad, who taught me everything i know about cars is visiting from FL this month...so I had alot of help from him; however, we are chevy people, so this is a little different for us.

I took off the intake manifold and the 2mm hole is completely blocked. the inside surfaces of the manifold pipes are completely caked in build-up from the PCV system failure. So I have several questions.

1. I am considereing taking the manifold somewhere to have it proffesionally cleaned...can a local mechanic clean this for me? Isn't there a "parts cleaning machine" that they soak it in or something to get it back to pristine condition.

2. If I clean it myself, is it suitable to "soak" the entire manifold in cleaning solution? (the throttle body is removed, but the linkage is still on).

3. ALL the pipes and hoses are dry-rotted and broken...so I need to order them...I couldn't find them on the parts wharehouse site, so I guess these are dealer items. I will try to photo them later today and post them, so you guys can get a better idea of the ones i need.

4. There is an extra "hose" (rigid metal pipe) not shown in my manual coming from the bottom "basin" under the throttle body, and leading to somewhere behind my engine. It too was nearly completely clogged at the connection to the intake. Do I need to remove it and clean it at the other end too?

5. Do I need to remove the idle speed port at the bottom of the engine and check it? or is it normally not clogged? This is where the oil is separated from the crankcase gases I'm guessing.

Sorry about this extremely long post; if you can help with any of the above questions, It would help me alot.

Thanks,
David
