Be aware that the back (firewall end) cover bolt holes are blind holes, i.e., they are not drilled through like the rest of the holes. It is possible to get oil in the blind holes and when tightening the bolts down they will 'hydraulic' against the oil in the holes. You may think they are tight but they aren't.
I blow out the blind holes with brake cleaner then blow out the holes with compressed air before installing the bolts.
The bolts are 1" long which makes the back holes even worse to deal with. I have cut down those back bolts to 3/4" to make sure they have enough grip to tighten down.

I considered that but I checked my radiator and the fluid is green and the leak is definitely brown, not red for trans fluid or green for coolant, I've checked my oil filter adapter and it had very small leak but it was dry between the oil filter adapter and the rear of the engine it would be noticeable line of oil of it were coming from the adapter, my theory is when I changed my oil pan gasket I used the method of zip tying the gaiety to the pan rather than using the supplied pieces that holds the gasket to the motor, I think I missed the groove that the gasket should sit in

I actually just changed that, but I did finally find the leak, my oil pan gasket wasn't seating in the groove at the rear of the engine and it bent inward into the oil pan, new gasket put on correctly and not a drop on the drive way since, thanks for all your guys help though

Compared to other vehicles, not that bad. Lot of fiddling the pan around to make it fit between starter. The Felpro blue rubber gasket comes with plastic grommets which helps keep the gasket and pan on for tighten the bolts.

The exact same thing happend to me on my gasket. Its tight under there so its hard to see if its seated properly. I used thread to tie the gasket in place and rtv on the dip of the pan that goes under the bearing cap, let it set for 30 min and installed the pan.Mine pinched part of the gasket off on the first attempt.
