ok guys this has been a really bad day, but to get to the point i was putting the last bolt in for the oil pan and it decided to strip the threads out of the block. so i drilled dapped and put a heli-coil in, but the block stripped again but this time around the coil. any ideas on how i can fix this? should i drill it for a 12 mil? any help would be great

 

holy **** dude quit doin that!!

next size up from 6mm would be an 8mm, dunno if you could make theat work or not.

 

bump for suggestions
