D16y7 block cracked?
 

My name is Colin. I'm new to posting on here but I have a question I can't seem to find an answer to anywhere.

Working on rebuilding a D16y7 bottom end for boost. Took it all apart and as I am inspecting the block, I noticed what I believe is a hairline crack down the side of the crankcase. I would like to know if this is indeed a crack and will cause me issues, or if is there a proper way to fix it?

Let me know what you guys think. Thanks :)

I also noticed several other spots with these \"cracks". It almost looks like its part of the casting.

Yeah casting slag is what it looks like to me.

Agreed. It's just the casting.

Casting fissures... no worries at all. Run it. ;)

Appreciate the help guys! That is what I initially thought but just wanted to make double sure before I dump all this money on new parts for this thing. Thanks again!! :yas:

Also looking forward to posting more on this site.=)
