I have a 2001 Porsche 911 with about 75,000miles on it and i noticed that sometimes a few drops of oil will drip down off what looks like the drain plug at the rear of the car. It is only a very small drip. What can this be caused by? I tightened the drain a little before, but there is still a small drip. I have never changed the oil on this car yet as i just purchased it about 4 months ago. I have not had any problems with it and it was driven all the way from Las Vegas to Ontario Canada in about 2 days without any problems.

Thanks

 

I wouldn't worry about few drops at all. If it's a drain plug, torque specs are 37 ft-lb if I remember it right. May be aluminum crush washer was reused.
