Hello All,

After doing a general service on my 996, I found that the pictured sensor is leaking. Does anyone know what this sensor is, if leakage here is common and what needs to be done to fix the oil leak? Thankyou!

....by the way, this sensor is located on the driver's side, behind the left rear tire and wheel and is just to the right of the coil spring on the engine case (the the left of the pictured "variocam" casting...

Hi I am not too knowledgable with Porsche but on some of my Italin cars and on most newer cars I see sensors in that location and they are for the cam position. The cam timing is independently variable by the brain. Again I don't have the direct Porsche knowledge as some like "Loren", but seeings where it is and there's a Vario Cam casting right there I would believe it is safe to assume it is the same. Jim

I heard this leak was pretty common, and sure enough mine was weeping a bit also. I just tightened it up, and it seems to have stopped. Not sure if yours is worse off but you might try that first also.
