When you have oil leaks, knowing "where" & "how much" is the key to finding out the problem. You can: (1) check with another mechanic you trust (2) try to narrow down the problem area to help out in the troubleshooting phase of the problem (one dirty but helpful job you can do is to clean up the bottom area of old nasty grease/dirt. Then you can do a daily check and see WHERE the oil is from.) POSSIBLE PROBLEM(S): (1) the oil pan gasket really IS leaking, just like you thought (2) the rear main seal is leaking on the motor(cheap part, but expensive labor costs) (3) The oil plug (and/or it's little gasket) on the pan is bad.(hope this is it..cheap fix) (4) oil filter not sealed/bad/leaking/damaged....(long shot, but possible). Good luck
