There are two longer bolts at the front of the engine that need to be removed that are inside the upper oil pan and accessible only by removing the lower oil pan. You really need a factory service manual to be doing this kind of work,

Could the leak be coming from the valve cover above the alternator? I would do my best to check the area. If it was the valve cover, the alternator would be covered in oil. Let me know what you find. I'll do my best to help. Post some pictures of where you're at.

Oil leak
When everything is put together behind the ac compressor is where I seen oil running down the back wall,so I took everything loose and discovered fresh oil in that area so I really can’t get to it so I just seal around that area

Well that's ok, not really important right now. Pick up a funnel when you can for this job. I would focus on these steps:
1) Clean that entire area the best you can with Gunk and whatever else. Make it spotless.
2) Scrape every bit of gasket material from block and pan mating surfaces. Get a drill and one of these if you can:
3) Use Ultra Grey RTV and new front and rear half-moon seals. Also replace the two O-ring oil pump seals. Mine were red from the factory.
4) Follow the FSM instruction for re-installation of the upper and lower pans.
5) Put the car back together, fluids and all and run it for a bit while it's up in the air so you can watch it from underneath.
If all looks good then you are done. I still wonder how that leak developed between the upper pan and the block, if that is indeed the source? Was there work done to the car before? Was the upper pan removed for some reason?
You're already in this pretty deep. Take your time and do good work. This is a big job you are doing!

i believe it was took down before cuz da seal was caked up like they used two bottles of silicone but they probably didn’t take it down correctly like fsm said do and cuz that leak I’ma make sure everything by valve covers r good but If the leak is coming from upper pan and block what I need to do at this point?
What you need to do at this point, is just put it back together! Replace the seals I mentioned, get some Ultra Grey (get the squeeze tube, don't bother messing with the caulk tube) and follow the FSM section on upper and lower pans.
I numbered the approach I would take in the above post.

Ah, so it's been worked on. Makes sense. But now I would want to know why?

It would make sense that your leak is coming from that corner. If someone previously had the pans off for whatever reason and botched the re-installation, that would be the area most susceptible to poor workmanship. A leak on any corner of the upper pan would be relatively profuse, as the crank case is under quite a bit of pressure. Any weakness in the upper pan and block seal would be a big deal.
The only other place I can think it would be coming from in that area is the front timing cover in the lower/affected corner. Do we know it the front timing cover has been off? The RTV in your pic looks factory.

that's what I’m thinking But I just learned that they’re gaskets round timing so I’m thinking I have to change all that but it’s gaskets and getting to it.well it look like it’s a lil less work then that upper pan.....just gotta loosen motor mounts and jack it up high as I can and work from there

Hopefully he can get it sorted quick. You did a good job though. It certainly could have been an upper oil pan leak and you did that job yourself. That's a crazy big job and most people wouldn't have even thought about trying it. So congratulations, you're crazy!
