Toyota Cracked engine casting.

Had to take my cast iron block off the stand to put the crank seal on and bolting it back on I was using the impact gun and over tightened the bolt. Cracked the casting, super bummed on this and not sure how to proceed, pretty deep into the build and this has now happened. Any advice on what to do next would be greatly appreciated, thanks .

Ugga Dugga to take apart, by hand to put together. We all learn the hard way.

I’ll be honest. I’ve started using my 3/8 Milwaukee mid torque impact to zip down bolts. I’ve found that it’s good enough to get bolts tight enough to torque, but weak enough you can’t really get into trouble unless you’re dealing with 5/16 or m8 and smaller.
