Mine has a crack in the same spot but it was bought like that and didn't see it til I started the engine and saw oil leaking out.

Got the crack tig welded, and just plugging up the pin sized holes with jb weld.

I am guessing maybe a rearend accident pushing the bellhousing. I bought it from a salvage yard, checked the VIN, CARFAX said the car was
wrecked/totaled.

It cracked the wing of aluminum behind the oil galley plug and the crack went down all the way to where the oil pan meets. Only thing I could do was slow down the oil leak so far. I am building up another block instead.

Here's mine. Goes up the oil galley. It even penetrated to the opposite side right next to the rear cover.

i am thinking the stress of the transmission pulling on the motor during installation cracked mine because it didnt start leaking until the transmission was just about all the way on the motor...

Just asking because I have heard that its possible with a stock motor mount and a poly trans mount to crack either or (block/bell housing). Motor is "tweaking" and what not why the trans is not due to the poly trans mount. Just what I heard...

I am running stock motor mounts and a poly mount on my trans, t-56 though ( M6 ) in a very low power application, do you guys think that I will have a problem with this set up?

turns out if i would have left that spacer out everything would have been fine, i tested it 100 times on the converter and on the crank to make sure they fit together, but never took into consideration the converter just might fit on the crank without it, what a major **** up that was...
pretty much sucks, f-body central says less than $3k and only a couple of days and i should be back on the road...
