I've always noticed a little oil seep around the front bottom of my engine, from the area that would indicate oil pan gasket. Since I never needed to top off the oil much between changes, I never concerned myself with it. But changing all the belts last night, I noticed the oil leak would appear to have gotten worse. There never is a puddle in the driveway. It just seems to be wet oil stuck to the bottom of the engine. And now there is oil forming on the bottom of the oil pan. I do have a gravel shield intact. When I had the timing belt changed I also had them do the front seals. There was no leakage from there. Or so they said.

Could the leak be as simple as changing the gasket? Is that a big job? Should I pressure wash the bottom of the car and then drive around a bit and hope to find the source of the leak? Thank you all.
