On your switch question, the one that activates when you release the throttle is idle control switch, the other is the WOT switch and should only activate at WOT.

Well the first try to start was a failure. When I turn the key I just hear a relay clicking and no crank. It was cranking before I started working on it. Was able to get it to turn over by jumping at the 14 pin connector. I tried to jump it at the relay and no go. Dont know what's going on now. Will look more in depth tomorrow. I did try to jump the fuel oump and the starter to see if she would start that way but nothing. It sounded like one cylinder was trying to fire but that was it.

So I guess I forgot to post pictures of everything after it was finished. Here are the last few pictures I took. If you see anything incorrect please let me know. I still have not gotten around to troubleshooting the no turn over issue. Just haven't had much time to mess with her. I do want to go ahead and get the timing belt and associated parts replaced. I guess now I should be shooting for starting and driving her in the spring.

Just look at those beautiful brand new hoses... Thank you again random donor!

Well she doesn't live right now. She gives me such a headache. And cosmetics will come once I can drive it!

I like your project, lots of work and nice clean up.

Question: I observe the WUR but it appears to be in a wrong location. It should be mounted over the water bridge, engine front two bolt holes available waiting for it. I also did not see the appropriate vacuum connector (and associated lines) in line to the throttle body. Maybe you are doing something custom?? or this could be a contributing reason of no start.
:eek:

MPDano 10-30-2013 05:51 PM

Man, I'm going blind. Now I see a FPR and Rails. Ughh.

What are you seeing as the WUR? I didn't think my engine had one as it is L-Jet I believe. Wasn't that only CIS cars that had it?

I miss-spoke...not the WUR it is the AAV that I see is not located properly and without the vacuum connector and lines...

I assume you are talking about the thing sitting by my strut tower with the 2 10mm vac hoses and one smaller one that goes to the throttle body?

It is attached to one of the lines going to the fuel evap canister and then to the large port on the bottom passenger side of the throttle body with a T going to the AC idle valve thing. And I have attached the smaller hose to the throttle body according to the diagram under my hood... At least I think I got it right.

From the pictures I believe that the AAV is not mounted properly onto the water bridge where it would be secured by two bolts to the available two holes. From there, the larger side is facing forward with a T connecting to the AC idle valve. Out the back side facing the throttle-body (TB) would be a vac. hose run over the longer part of the AAV to a vacuum connector and then on to the large port in the TB. The diagram is the guide but I believe your configuration is off.

From what I have read my car does not have anything that bolts onto those holes on the water bridge. Yes some cars have it but I do not believe my 82 L-jet does. If you could post a picture or diagram of the setup you are describing it would help me tell you how mine is routed. :confused: Or if you could circle what you are seeing on one of my pictures and then repost it I will explain what is routed where. I think that might be the best to do so you can know what is going on with my specific set up.

I do not believe my car has the AAV.

Here is how I have "it" connected. Best I can describe. The "____" are just to add spacers to make it look right, Ignore them lol.

_______________________>Small hose from top of "Valve" going to upper part of TB.
Large port on TB > T > "Valve" > fuel evap canister
________________T > ac idle air valve > port on front of spider intake



The "Valve" that I am referring to is labeled "V" In this picture.

And is at the top left of this picture:

the AAV is located in your latest engine picture on the back left valley between spark plugs and center. You will observe the two holes I mentioned ready to be lined up with the two holes on the water bridge waiting for it.

It is not the plastic valve in the other picture.

whatudrivin 11-04-2013 10:28 AM

I see that now... However I think it was meant to be in this location maybe? idk... With the formed hose I don't see it being able to be moved. And the connector that is plugged into it cannot be routed anywhere other than where it is. And it is connected into the hard black pipes that are going into the heads. Maybe this performs some other function in my car?

Also notice in the last picture I posed it has it in the same location. That is a random picture I found from google.

JhwShark 11-04-2013 10:50 AM

It is what it is! The AAV. There is only one proper mounting location I know of from reference manuals. The larger side should be facing forward with a T connecting to the AC idle valve. Out the AAV back (longer) side facing the throttle-body (TB) would be a vac. hose run over this longer part to a vacuum connector (other hose connect here) and then on to the large port in the TB. The hose from the AAV does not connect in the back of the engine where you have a hose connecting from what is the front of the AAV.

The AC idle valve vacuum lines in a previous picture are also not connected properly...

Take a major re-look at your vacuum lines, parts and configurations. Re-install them properly and you may be able to start the car.

Look into the Porsche workshop manual for confirmation. Google is not a source for anything except a lot of information...if you want high value information then this board is the source or a manual. Your choice!

Two wrongs (location) do not make a right!

Anyone else want to confirm the AAV...SmileWavy

I had been looking at the manuals and the diagram under my hood. None show the AAV on the water bridge. This is where it was located when I got the car and I know it had been running with the configuration the way it is. Not saying it is right though.

Also I have everything hooked up how I believe the diagrams showed. I've searched this board and Rennlist for diagrams for hours trying to get everything connected correctly.

I'm trying to find information on what this is that you are pointing to but not finding anything atm. However I did find a picture of one of Landseer's cars that has the same thing I do in the same location.

Bump, Since I see Dano is online maybe he will see this. SmileWavy

Can you give any insight into this Air Valve situation?:confused::confused:
