I know this issue has been overly discussed on the forum, but I need some opinions here. About 2-3 months ago my car was overfilled by a German specialist who actually has a good reputation in Northern VA. The car was towed to their shop and they acknowledged overfilling it. They drained it, but I still was getting drips of oil right next to the rear left tire area and occasional clouds of smoke at start-up. When I took a sharp corner last week smoke bellowed out from that side. I took it back and they said it's definitely not overfilled and cleaned out the intake pipes again. It still dripped oil, so I took it to the Porsche dealership in Tyson's for a diagnosis. They told me it's not overfilled and everything looks fine. He did state that I might see some oil dripping for a week or two. My car is still leaking, I got on the car quite a bit yesterday and it leaked more than usual. No lack of performance like when it was overfilled, but I hate to see my car leaking.

Can someone let me know their thoughts on this? The dealership is willing to take is back for further inspection.

 

I would have it looked at by the shop that over filled it at their cost. If you don't trust them try another shop.

 

What rmc1148 said.


Couple of additional thoughts...


If the engine was overfilled with oil chances are oil got into the intake system. Which means oil got into the intercoolers. Intercoolers occupy the lowest spot in the intake system.


Oil in the intake system, the intercoolers can take a long time to work its way out on its own.


IIRC the recommended way to deal with this is to remove the intercoolers and clean them along with all the hoses. The intake system has a lot of surface are and if this has oil on it...


If the cleaning isn't thorough, since the intercoolers are located at the very bottom of the intake system they'll collect over time any oil left in the intake system.


Might mention here that when the intake system is off the car that a careful inspection of the partially exposed/visible compressor wheel of each turbo needs to be made. If you see any oil on the compressor wheel this can be due to a turbo seal leak and to address a leak in this area could require a turbo rebuild, possibly even replacement.


Also, you report a drip. This is not likely coming from the intake system for this would require a leak with the intake under atmospheric pressure.


Thus this suggests the leak is coming from some other place.


You have to get the car up on the air. Look at each turbo and the lines/fittings/hardware around/under the turbo.


The leak can be from any line, connection, fitting, seal or gasket and probably unrelated to the fact the engine was overfilled with oil.



Also, you have to verify the leak isn't from something above the turbo, higher up on the engine.


Check the camshaft cover and anyplace above each turbo from which oil can leak.


Sometimes id'ing the source of an oil leak is as much a function of id'ing from where the oil is not leaking...

 

I've seen this before, the oil gets in to everything. It will take some time to purge out.

 

I did what you said, I took it back three times and they compensated me for all the bs I went through. I just gave up and took it to Porsche. They charged me $69 to look it over, but I am taking it back soon because its still leaking. I told the dealership to do whatever was necessary with regard to draining oil and refilling or inspecting parts. The guy said everything was fine, I was told to drive it hard to push all the remaining oil out of it. Porsche of Tyson's services a good amount of TT's so I am confident in what they tell me. My car is still leaking though, so I remain a little unsure at this point.

 

.... just.. drive.. it.....

though overfilling these for the reasons macster states are anathema to these motors.
