My dad drilled a hole through my block the other day trying to drill out a bolt, now I have an oil leak on my front cover..we tried to patch it with something but I don't think it worked, is there anything that you guys know of that can bond to Cast Iron to plug a hole or stop a leak? or am a screwed and need a new block after rebuilding my whole shit?!?
thanks

 

'JB weld' should cure it... you can get it at hardware stores... a guy i worked with had a busted a hole in a tranny, we patched it with jb weld and it held perfectly, shit it even matched the color of the tranny. good luck man

 

Yep, JB weld will fix it. I've seen many exhaust manifold studs drilled too far into water jackets, and with a little patience, JB weld patched it up great.

 

make sure that you clean the area around it very good or the oil stains and grease will weaken the bond.....

 

Here's a thought...thread the hole that was drilled out and stick a bolt in it with a washer. You could even JB weld the threads on the bolt before you thread it to give it that extra sealing bond. Good luck.
