Reply to "Snapped bolt in block - how deep can this be drilled?"

angelobMember

Bolt is finally drilled out and retapped! Would not have been able to do this with a hand held drill. First, I had to remove water pump and resecure the backplate to keep it from flexing when I put pressure on the drill. In hindsight, it would have been a bit more secure if I mounted a thicker plate in this area for the mag base, the existing plate, being so thin really cut down on the gripping power of the base.

Pump area cleared for mounting drill

Drill mounted and aligned for drilling:

Carbide bit starting its work

Starting to run the tap, then bottomed out.

Thinking I better pull the balancer and timing cover to make sure no metal went behind that plate, might as well check the timing chain and gears.

Thanks for all the input and ideas! Have a chance for it to be back running by the weekend!
