The short version the three bolts that hold the motor mount to the block have stripped out. I have drilled them out once and rethreaded them with lock threads and they recently broke the second set of bolts. This is starting to irratate me to no end what can I do at this point shot og buying a new block?

 

drill and tap them a bigger size? Thats all i can think of. Those lock threads dont work for **** if you have to torque on bolts.
