Oil leak

[Ghostrider]

Hy Folks,
I have a 2.8 30V in my Avant quattro. When the car sits overnight, there is a fair amount of oil that leaks in the front, as in just behind the bumper. Car gets driven for about 10 minutes +/- in stop and go (my commute). When I leave for lunch there is a minor spot of oil 2-3" in diameter. Is this the dreaded oil pan gasket going? I just had the engine replaced (old one overheated and I head one head cracked). When the mechanic installed the new engine (68K), he filled it with synthetic oil.
Thanks

um i would just jack it up and see what's going on!! its that easy.. if it was a mystery leak and it was leaking in more than one spot all at one time then it is most likely a clogged PCV valve.. but please jack it up and take a gander for yourself before posting!!
