Quote: Well Mike, just thinking out loud here, You know there was piston to wall scuffs, and there was one bad enough for yu to want to sleeve that hole, could the aluminum have come from there? I know its a long shot, but it could have, also did ya use ARP lube on the bolts? That has made a mess in my pan before, and it didnt take much.
Just poking things around a bit.
The pistons were coated and the coating looked great so that wasnt it... I'm looking to use my other block which has the correct bore for the pistons then start over with it... I'll just transfer the guts into it but its gonna need to be decked... this engine was a error on my part to begin with... I should have grabbed this other block from the start and went with it
