Today I noticed that the passenger manifold is fully coated with like an old oil, but the driver side nothing top of it, is that because the oil tank located in the passenger side and the leak reached the passenger manifold ?

Anyone has this issue before ?

Thanks

 

Put the car up on a lift and run it. Could be just a turbo line leaking or something simple like the valve cover leaking. It's unlikely that your case or heads have sprung a leak, probably a simple fix. A main seal behind the clutch is another likely possibility.

 

Who did your last oil change? Possibly overfilled? Do you get smoke at startup?

 

No smoke at start up , porsche dealer filled the car

 

Maybe something obvious? Check that the oil filter cap is tight.

 

Yeah you are right maybe the cab I will check it
