Help to locate oil leak from right side 03 Turbo

[kausi]

Started to change oil on my cayenne turbo and found major oil leaks on front right side. Oil was almost driping from generator/alternator. But as everything is built so tight together it is allmost impossible to locate the cause. I think if it would be the turbo it would be more back to the car? Any suggetion what to look for or how to identify the oil leak location?

Two possible approaches:  Thoroughly clean the engine bay, then start looking for the leak source.  If that does not work, you can add a UV dye to the oil and use a black light to try to isolate it.

I'd start with taking a mirror and following the valve cover gaskets all the way around.  That's the more common area for oil leaks that drip down the side of the motor.  And, on an 2003 car - you're likely going to need to replace those from age if you have low miles on the car.
