I tested my boost track again and have found a huge leak. I think this is where the PCV valve is located but I'm not sure. Bentley calls one of these components a "Check Valve". It gets inserted in an assembly of rubber bits and clamped together with the one time clamps seen in my pixs below. Is this 'Check Valve' what is commonly referred to as a PCV valve in audi-speak?

The Bentley diagram shows another piece it calls the "Evaporative Emission (EVAP) canister purge regulator valve -N80", is this what could also be commonly reffered to as a 'PCV valve' or is it the former, both or neither? When I went to the dealer and asked for a PCV valve, they gave me something that looks more like the aforementioned "check valve", with a part number 035 103 245A, but the part description on sticker on the bag does say "PCV Valve".

I am also looking for a source of the tool that allows removal and crimping of these one-time clamps. This location is tight to get to, so I've been thinking this might be a good place to use them, assuming the tool is small enough to move around in there.

On a related note, when I capped off the throttle body and Idle Control Valve, as well as the crancase breather, to test the rest of the intake tract I could hear a very small leak, somewhere around the Waste Gate Frequency Valve. It was so small I have not been able to pinpoint it. I am fairly certain it is not coming from the tester connection at the MAF to Turbo inlet hose. I felt around with my fingers and could not detect a leak. I also tried soapy water, but that didn't help either. What seemed odd was that the leak was more pronounuced between 7-10 psi, above 10 psi I could not hear it, but as the pressure dropped and hit 10 psi, I could hear it again. Any ideas?

Cobble a rig like Sam has in the picture, and you can quickly test your valve.

Tool to remove clamps - large wirecutter - or a Dremmel tool with a cut off wheel.

Tool to replace clamps - screwdriver - use common hose clamps.

You leak by the WGFV - not a leak - your BPV. (Closes with boost. Opens with vacuum.)

STFA - all has been discussed.

Thanks for the pic of the rig.

Was hoping part numbers could be posted in the thread so that all could be found together, since I didn't find exactly what I was looking for in my previous search, so thought I'd ask. Guess I won't ask next time.

Didn't think it was BPV as noise was not coming from there, but I'll listen again (BPV is about 2 years old, Forge 007).

...I could have sent you the part numbers... And YOU could post them - as my pic poster is full of what I want in it.

*hint* give me your email address *hint*

I had a couple of JPG's ready to go just after I did my first reply of everything he asked for - and no way to get them to him.

A hint to all of those who want help - accept the help in what ever format the helpers offer - it may not be the way you want - but it may be just what you need.

Ignore this bum. He is at the mercy of the stealer.

Touche! Well spoken.

Hopefully this helps someone else out in the future.

In the first place, your original response Bill was not an obvious hint. Even though I thanked you in my response and explained my intent you chose to be melodrammatic.

You and your friend there are kinda tightly wound up.

A typed list of part numbers would have had errors from my fat fingers - and would have had questions from you as to what was which. Screen prints are clear and concise - with no room for errors.

Why do you hide you email address? are you hiding from an ex wife or something? In 3 years - I have had not one bit of spam from leaving mine open here.

I spent time on putting your answers together - and you prevented me from sending you that answer by trying to control the way I answered - and you do not seem to realize your (in)actions.

Sorry for my part in this - I should have asked for an EM addy before researching. My bad.
