I have checked the motor all over top to bottom and front to back and the oil appears to be isolated in one particular area of the engine.  The leak appears to be in the area of the back of the oil pan and the front of the fly wheel cover.  I noticed the leak this morning while changing the exhaust out.  I was thinking the rear main seal might be the source but when removing the fly wheel cover I noticed only the 4 back bolts of the oil pan had oil on them all others were clean.  I checked and they a little looser than the others so I tightened them a bit.  Only the front of the cover appeared to have oil on it and when it was removed the clutch and inside of the bell housing appeared to be oil free.  I cleaned everything up before putting it back together but after coming back from the show (15 minutes drive) the leak was back.  I could see the front of the oil pan had oil on it and it was dripping from the bottom of the cover.  I am thinking a bad oil pan gasket but am open to other opinions.  Thanks for the help.
