Porsche Cayenne coolant tee failure (plastic)   Leave a comment

Porsche Cayenne coolant tee failure (plastic)

We are working on a 2008 Porsche Cayenne V8 Turbo. The vehicle developed a coolant leak behind the engine against the firewall. After painstakingly gaining access, we found that a cheaply made plastic coolant tee connector had become brittle and failed. We obtained a parts schematic from Porsche but nothing in the diagram looks like this. This part is probably a Volkswagen part as the Touareg is built on the same platform. We could install a brass tee with hose barbs on it in place, but will give the dealer more time to produce the correct part. We may find that the part is available only as a hose assembly. We will add the correct part number and a picture of the new part when we find it.

1960 Porsche 356B Cabriolet: getting it to run   Leave a comment

Unloading the 356 from the flatbed directly into the shop









Clean engine compartment. Some finish detail not original but this will be a driver — not a show car.






Carburetors after a basic clean and rebuild. In the future we may opt to send them out and have the finish corrected to factory. We also have one partially melted booster that may require carb body replacement.




Here is a 1960 Porsche 356B 1600 that has had a recent “restoration”. We had the car towed in from its storage place, “the owner’s garage in Boca” where it sat for over two years. I replaced the battery, checked the oil level, drained and added some fresh fuel, added a small amount of fuel and it started up. The carburetors need to be overhauled / rebuilt. We ordered new points and spark plugs. The fuel petcock drips slightly, so we ordered a new one from Stoddard. The owner wants the seats rebuilt; they are springy and real soft. Will post more on the progress later. -> JASON ATHANAS 






interior is real clean, fresh restoration



Dash is in excellent shape. We are going to recondition the steering wheel with Dupont Imron paint.

Porsche Cayenne brake booster failure warning   3 comments

We are in the process of diagnosing this 2005 Porsche Cayenne Turbo S that has a warning on the insturment cluster indicating "Brake booster failure". We have checked vacuum to the brake booster and the electric vacuum supply pump. We are suspecting the booster itself. It has a pressure / vacuum sensor and a travel sensor in it. There are no codes in the ABS system or engine system — just the warning on the dash. Access and testing is quite time consuming. Will post the fix when we find it.
This warning would come on for 10 seconds when the vehicle was started and then just the small brake warning would remain lit.
The brake booster held vacuum, pressure and travel sensors tested ok. Brake booster replacement did fix this problem but double check the vacuum line as ours was brittle and broke as we were removing the booster. Vacuum brake booster line cracking is a common problem — especially at the line just under the electric vacuum assist pump.
