Default Wtf is happening

I just got finshed my engine. But I have leak at the botom of the half moon on the oil pan gasket on the front. I have checked the pan for warpage and damage, I have checked the gasket for damage. Then as an only option I went to check the timing cover bolts and the 4 bottom ones were weak almost broken, when I tightemed them they broke. Those 4(two on each side) were the only original bolts I used. But would that cause the pan gasket to leak. I have checked time and time again it it definitly the very lowest point of the half moon on the front of the engine. Its not the timing cover.

Doesn't the timing cover seal into that area of the pan gasket?
If the timing cover is not tight to the block it is not going to hold the seal into the pan.

Thast exactly what I see and know from expereince. I squeeze my hand in and feel all up the side of the timing cover and down and arround the bottom, and the bottom is the only spot i feel oil. I can even watch it drip there while the car is running, and for a few minutes after. I am so damn confuse and frustrated. The first time I pulled the pan I toought I found the issue when I had a small slice on the outside lip of my pan gasket. So I replaced it. Same thing. So then today I removed the two diagonal frame braces and everyhting that was in the way so I can do that portion of the job as cleanly and easily as possible and I still have the problem. I am gonna fix the timing cover bolts and leave the car apart as far as I can so I can try it agian if it fails AGAIN. Still any imput would be much appreciated.
