Hi
I have a 06 Cayenne Turbo I just bought. I had Porsche do a PPI and most everything checked out well. I noticed that when I really beat on the car at High speeds I get an oil leak on the drivers side front. The first time it happened I wiped everything down could not find where the leak was coming from but it did not leak oil again. On Easter Sunday I was showing a friend the cars performance and sure enough when I got home it was leaking again. Any thoughts of what could be causing this?

Many thanks

Probably blow by from the Turbo. It collects down in the driver side intercooler down pipe. Mine is doing the same thing. There is an O-ring that connects the Turbo to this pipe that needs to be changed to fix it.
I have the O-ring at home just havent had the time to change it.
The oil there is well known and is part of the Porsche oil change procedure to empty the tube.

 

hi Justin
Many thanks for your reply, Is there a procedure document some were for this? This is my 5th Porsche but I am very new to this one.
Thanks

This is the procedure I am going to use. Someone else on the forum did the DIY and I am just passing it along.

 

Perfect, I will get the O-Ring this week and start in on it this weekend

Thanks Much

 

Just what he said. I drain my lower intercooler hoses about every 15~20K (every other oil change). Some crankcase bypass oil will condense in the intercoolers and you may get anywhere from a couple of ounces to a cup or more of oil depending on oil type, driving style, mileage, etc...

 

I have an 06 S and I found that there is an oil leak between the transmission and the pump. I cannot tell for sure where it is coming from and my local mechanic told me that he needs to take off the transmission to confirm where it is coming from.
It is a long job and he needs to fix a time for him to do it well in advance he says. Anyone has any knowledge or experience of this kind of oil leak between the pump and the transmission? I do not know if it is the pump leaking or not.

 

Would anyone have the part number to either the OEM o ring or the upgraded green version?

Thanks!
