oil leak, no significant drips in the garage or driveway before this trip Options

[DRPHIL914]

Ok i just got back from Florida, first trip with rebuilt transmission and new muffler. so i guess i am around 750 miles on that trip, 1500 since last oil change and looks like i was 1/2 quart down. motor has 60k miles total on it. motor and transmission were all out 3 years ago during the time the car was getting repainted. i had a front seal leak and replaced it along with all the push rod tube seals. i did have a slight leak from the oil filter adaptor for the Aux oil cooler, which was taken care of last time i did the change and that was about 4-5 months ago.
it looks to be coming from the area of the oil pump or maybe the front seal again? i am posting a couple pictures too but i might have to scope this, best i could do for. ow with cell phone. i only found this as i got home a few hours before and was just doing a quick check and was going to work on making the new valance, noticed some marks on under side of the muffler, looks like oil drips being blown back onto the muffler.... anyway kind of sucks ans i don’t have time to drop the whole bit before Amelia and Werks reunion on Friday.

any thoughts would be appreciated
