Oil Pan Gasket Replacement - Now it leaks even more oil.

[1Oldman]

The fact that it only leaks while it is running suggests that it is pressure related. I would suggest looking at and tightening the oil galley plug on the right side of the engine just below the crankshaft. Another thing I'd look at or rather just go ahead and replace on general principles is the oil filter. Oil leaks can be difficult to trace because the wind tends to blow the oil around. The best way to trace an oil leak is to thoroughly clean the engine, like at a coin-op car wash, then ride it home and shut it off and immediately look for the leak before it's had time to blow around.
