I am busy with stripping down the intake manifold to get to the plastic coolant pipes as I have a huge coolant leak somewhere. Have taken out the top three plastic pipes and found no tears or leaks yet - but are going to replace them anyway with the upgraded version. I found a hole - or it looks like a breather/vent pipe T-Connection - just behind where the three pipes connect closes to the firewall. Does anyone have a clue what hole this is? I dont think it is where my coolant leak is coming from but all the same it looks like it shouldnt be like that. Best I could figure out was that it is possibly one of the vent pipe connections for the turbo. I have a 2006 Cayenne Turbo S. Also, if someone has the Porsche Work Manual how to strip all the bits and pieces handy, I would really appreciate it if I could buy it off you - I am having difficulty in registering on the PIWIS site and therefore cannot access any of the much needed manuals. Anyone done this on a Turbo S before?
Thanx for the great forum!!

 

Wow I am starting to think this site is not worth my time, doesnt anyone have any advice or knowledge to offer? My question has been read many times but no replies? PLEASE guys I need help and that is why I joined this forum. Thanx!

 

sorta looks like the AOS overflow tube but I am no mechanic.

could try here

Pm your fax number and I'll send u over whatever u need. Just let me know. I can't tell what u are referring to in the pic. But there are no other coolant lines in the back. So it's a vacuum or vent line.

 

I presume you read extensively about this problem on this site prior to throwing stupid comments around

This is well documented here, you want instant help go to the dealer

 

Echerbst: Thanx for your offer to help, I will PM you.

Mudman2: Yes I have read and read and read everything there is on rennlist as well as renntech and quite a few guys mentioned this white T - but nobody posted any consistent or factual answers. Who are you to call people's questions or comments stupid??? If you have a bad day dont take it out on others. If I didnt need help I wouldnt have asked - if everyone could just get the answers from their dealer there would be no need for DIY discussions on the forum! You are missing the point I think.

 

Patience is a virtue, 2 hours is a very short period of time on message boards so getting irate makes no sense

This board is not a technical DIY board although you will find that here, it's not an on-demand answer machine

Renntech is more the pure technical center

 

A comment like the one above isn't going to sit real well with a lot of folks here and they're not going to be in a big rush just because of your attitude.

 

Hey! Looks like my comment could have caused offence to some. Sorry guys, didnt mean it that way - it was more a case of me being at a total loss and desperate for some help. Thanx

 

Sorry mudman2 - it wasnt 2hours but more like 4days - apologies if this came over the wrong way, I just thought that nobody was out there.. Thanx for the advice on renntech, will try them as well.

 

I see you have a Turbo. The "T" resides behind the intake just on top of the transmission.
According to a tech friend of mine, it is a bear to fix.

If you are getting leaking in the rear of the engine, the plastic "T" is probably the culprit.

HTH,
Scott

 

Thanx Scott, I have taken the plastic T out already (actually there is two T's - one is connected to its pipes with special non removable clamps and the other one is just below that connected with normal clamps). It WAS quite a challenge getting them out :-)
Both looked fine to me so I am still searching for my leak. This little white T in my picture is the only thing I found broken - and the description on the PET for its replacement (it forms part of it) is called the "Vent Line Bleeding Crankcase" just for information.

Definitely replace the plastic T's. They get brittle and crack. They are very difficult to get to even when you have the manifold off changing the coolant pipes. Mine were not change at the time the coolant pipes were changed with the first owner and then cracked on me months later. Pain in the Butt. Sorry I can't help with the identification of the other little white T.

 

Suggest you take your vehicle to a dealer.

 

I'll post more tomorrow from home, with pics, etc., but I also snapped off the little white plastic tee in your picture when I replaced my coolant pipes and the rubber tee-hose. It connects to a vent line, which I think runs to the front passenger side.

I wanted to buy just a replacement for the brittle tee, but they only sell it as part of the vent line. So I picked one up at the local dealer for something like $120 (service guy said their crew breaks them all the time), but then got the idea to just replace the little white brittle connector since the vent line was fine. Ran to a local auto parts shop and picked a multi-pack of similar connectors and went that route instead.

The hardest part was fishing out the tiny cracked pieces of white plastic stuck in the black hoses to the left and right in your pic. I literally cracked them with pliers and fashioned a hook out of a wire hanger to pull them out.

(And for the record, I feel your pain on the desperation and wanting answers quickly. Though not technically oriented per se, this board is ridiculously full of deep DIY knowledge. )
