We'd all be guess on the location as well. Have someone local take a look at it on a lift to determine where it is leaking from.

Jason Zane

what general areas do you see it?


If it's motor oil and you have the 3.8L V6 it's most likely the upper plenum. If you have that engine and the upper plenum and lower intake gaskets haven't been replaced yet that's the most likely suspect. Have both the upper plenum and lower intake gaskets replaced together if you decide to do it. HTH. -Jim
