In the picture below is a crack in a a6 block I have along where the middle main cap is. Would it be safe to run? Or is it trash?

 

maybe call some shops see if they can weld it up and machine it. more pictures with better light! im sorry dude :/

mains are pretty vital but there may still be a chance...

 

im sure if you drilled both ends of the crack , so it wont crack anymore then weld it up, and somehow machine it flat it would probally be okay .. but finding a shop to do all this would prolly cost more than finding another block..
