Well I finally found out where the damn leak is after replacing outshaft seal and flange and doing the t-case lower cover re-seal to no avail.
See pic below and if you look at the slot above the t-case goop and below the far left bolt ( basically just to the left of the flash middle) you can see the slot where it is coming from. not sure what this is or what is gone ( or going) to allow the oil to come running down this slot!
any ideas and info would be great ! thanks and let me know if you need more info or me to expand on where it's coming from!

 

I would power scrub that entire truck, what an oily mess. Once clean you will get a better idea. If it is just a seal, might want to consider buy a bottle of White Shepherd oil stop leak and follow the directions.

 

it's leaking from the exact place I described!
