Cato .... was that the reservoir you replaced as seen in the first photo?

If so then that's the coolant reservoir ... not the washer one .. which means we're talking about totally different areas of the car.

The washer bottle is in the right front wheel well behind the splash guard ... the coolant reservoir (expansion tank) is in the engine bay at the rear corner.

** the link to the wheel well pic is incomplete and didn't work

Here's the coolant expansion tank ... #38

I just fixed that link and can see the pic of the wheel well ... and it does look like the canister and hoses are missing.

Post lots more pics of your engine bay so we can see what's going on with hoses.

Here's your pic ..

I think this part must be missing...

Here are some more photos:

Check the clear reinforced line which goes through the inner guard. It looks like it's been put in as the tank vent line and the carbon canister has been removed. It goes off to the rear behind the washer bottle ... has a connection there been disturbed and what is it connected to? ... where is it connected to in the engine bay?
Edit: just looked at that line again and wonder if you've made that your washer bottle fill tube?

Are there any other hoses not connected to anything in the engine bay? ... take pics if there are.

On the right side of the top photo in Post #19, there is a metal valve with a small vacuum line sticking out of the top. Is there a large rubber line on both the fron and the rear of that valve? Are they both connected?

Are there any open or broken large rubber lines anywhere in the area?

CatoBT

The reinforced clear tube was indeed used for the washers (lights). Now, when I removed the original washer bottle I simply used this tube for filling the washer bottle (not a perfect sollution, I know, but as I said: I really don't drive in rain so the windscreen washer is just there to pass the bi-annual checks).

I can't find any broken or cracked tubes. But again: I can't find the canister either. I guss there must have been some rather makeshift "repairs" done here. My best guess now would be to rebuild the vacuum system to original.

Is it possible to buy the parts? Esp. the canister...

More photos will follow later today.

If you know somewhere you can get secondhand parts then that would be the way to go ... with new hoses. If you can't get parts over there you wouldn't have any trouble getting them from the US.

I'm wondering what's left of your fuel tank venting system.

CatoBT

Ok, so I looked for hoses going nowhere...

There are a few, but I doubt if they have any influence here.

BTW: There is some sort of black canister inside the LH wheel well:


And I found some strange hoses (this one on LH side):



And this one in the front:



I'm starting to think that maybe this is an impossible task... :-(

Should I give up this car and break it for parts..?

UPDATE: It looks like here in this post that the charcoal canister is something made for the US market? I'm thinking about posting no. 4 by James Bailey:

Still no sollution

All advice still highly appreciated!!

1.. The first pic shows the vacuum storage for the cruise control. There will be some small vac lines going through the inner guard to it from the engine compartment.

2... The second pic is of the four way vacuum connector. There is a line that goes to it from the large vacuum line going to the brake booster, with a black and blue check valve in the line. Another line goes goes through to the cabin, another to the cruise control ... and if you look carfeully you'll see that the other white fitting is a plug (not open). The plugged line does not have anything connected to it.

3... The third pic is probably the old adjusting line for the headlights, which would have gone to a headlight adjusting **** next to the drivers seat. The old adjustment mechanisms don't work and can be taken out. Solid sections can be put in the headlights to lock the adjustment.

4.... It seems that someone has removed the charcoal canister and a lot of the plumbing. You can do without the canister, but it's essential that your tank venting systems still has the basic system intact and a line to the motor to draw vapours from the lines for basic emission compliance. The charcoal canister is a standard part on all Australian cars, and is plumbed exactly like the diagram I posted from PET. The canister shown in the other thread is not a Porsche part and must have been added by dealers in the US prior to sale to meet regulations (strange they weren't imported with genuine parts in that area).

Don't give up .... its perfectly natural to feel that way but you'll sort this out eventually. When I got my 82 and found I had problems I felt exactly the same way ... but I'm glad I toughed it out.
You won't regret being persistent ... and you'll learn a lot about your car along the way.

I'll post again soon with some suggestions.

Dave928S

What did you do ... exactly ... when you put the washer tank in ... step by step. Knowing the exact detail might give a clue to the problem.

I see some wiring in the wheel well ... did you alter anything or just add on to the two wires there?

When you ran the tube through the inner guard did you move anything?

When you spilled the water where did you spill it?

Did you have to move anything or push wires or the tube past anything?

The car ran OK before you added the new washer tank didn't it?

CatoBT

Hi Dave,

Yes, the car was fine before I changed the washer bottle. A few times before it shot, but then it was completely normal after.

The wires are the new ones for the washer pump. I did not remove anything or cut any other wires. I did cut the hose going to the fron (headlight) washers, simply because I needed the hose to make a filling tube for the new bottle. Water spilled was only going down on the block on the righthand side of the engine.

Still I have no clue what is wrong, but thanks a lot for helping!!

And to do the step-by-step thing:

1. Tried to attach a new pump instead of the old one which did not work. The hoses going to the old washer bottle would not fit the new pump so that was not any good.
2. Opened up the wheel well and removed the old bottle. (The cables going to the pump for the front washers I just left there and put some tape around them to avoid any short circuits).
3. Put in the new washer bottle (it is smaller than the original one, and the pump is attached directly to the bottle) and connected to the power for the original noe using solid cables and connectors.
4. I cut away the hose going to the front washers, and used this as a filler neck for the new bottle.
When I filled the new bottle I spilled the washer fluid on the engine side (right hand) as the hose is very thin compared to the original sollution.

I did not alter or cut away anything (or move any cables or hoses).

I have found a Porsche workshop not far away from here charging 220 US$ pr hour. I think maybe I will pull the car there for assistance...

UPDATE: There is a (very small) chance I spilled a few drops down the air-inlet/inspection hole for the timing belt (the air-intake was off to enable access to the old washer pump).
Could this perhaps have caused the timing belt to slip? If so, maybe a change of timing belt would solv this?

I thought you pressure washed the engine, did you?
