New ATK Engine Leaking

[broncomemories985]

Hey guys, put a new ATK 302 V8 long block in my 77’ Bronco. Ever since, had a leak at the back of the engine where it meets the transmission. Upon further inspection: oil pain gasket dry, ***inside inspection door dry*** and re accumulates about 3cc of fluid without driving it. This is the original oil pan, for what it’s worth. Put some dye in it and here is what I found. Any help is appreciated thanks!

-There are threaded plugs on the back of the block that sometimes get forgotten about (no thread sealer).
-Some ford V8’s get hairline cracks in the same area decscribed above.
-Check the head gaskets in the back of the engine too.

Good Luck.
