I think it may be the front crank seal. Hard to tell. Anybody had to replace one? Any other things to check?

Haven't heard much about oil leaks on these engines, perhaps as we don't have that many older ones yet.

Possible oil leak sources on the front could be front crank seal, timing cover gasket or front of oil pan gasket. Not sure what GM uses for a gasket. Could be gasket in a tube or metal/beaded rubber gasket assemblies. Crank seal would be easiest to replace .
