Hi

Took the covers off under the engine to find a slight oil leak seems to be covering the sump and going towards the back but could not find the culprit. The sump nut is dry took the car to a Porsche specialist and told him to have a look while replacing the track control arms but said would need more time to look he couldn't see anything from valve cover gasket any suggestions before I take it back to him he did say that he might need to drop the engine if nothing was obvious!

It's an 2003 cayenne s with 103k

Thanks

Looking again under the car there also seems to be some red fluid Automatic gearbox fluid? also leaking not good at all anyone with experience with these? This car is turning into a cash cow. I have changed the coolant pipes a year ago too. I live in Bham in the UK anyone who has got time on their hands would appreciate the help don't wanna ditch the car.

 

Thanks

Transmission leaks usually happen after a coolant leak from the pipes.

The coolant finds it's way to the input shaft of the tranny and dries into a hard abrasive residue which wears the front seal.

The transmission has to be removed to replace the seal for the repair.

The scenario I described typically happens after the coolant pipes burst, it may not be in your circumstance.

If the transmission fluid leak is coming from a hole at the bottom of the transmission bell housing it probable is your front seal.

Found out that my oil leak was from the power steering pump plus the two pipes connected to it the high pressure and low pressure are quite corroded will need a new pump and 2 new pipes, the transmission leak is ever so slight so been advised to leave it and on top of that I'm on a search for 285/35/22 tyres anyone got any deals in the UK? :blush:
