Cracked Oil Pan??

[BlkMax]

I cleaned off the upper oil pan for putting the drain in for my triples and noticed this. There was a lot of gunk (oil and sand) on top of the pan and I just figured it was from 150k miles and a leaky oil drain on my HTT.

Is this a crack in the upper pan? I have never seen one out of the truck.

It looks to me like is runs through the screw hole and back to the block.

hard to tell but to me it looks like flashing left by the casting process

Thanx, I am beginning to think that is the case.

I have never seen one without the gunk on top...

Kind of funny how it runs from a bolt hole like that i justshipped out 2 lbzs and i have an lb7 sitting on the floor here and an lb7 in the truck and none of them have that casting mark very odd

Would this be something similar to the same thing? Just happened to notice this on my 2006 lbz. It’s in the exact same spot.
