torque limit on frozen water pump bolt

I had the same problem. Penetrating oil, heat, impact (electric with no balls), nothing, and I mean nothing worked. I wound up breaking the bolt head off when I used a 6 ft piece of pipe on the end of my breaker bar. :angry5: At that point I was able to pull the water pump off and attach a stud puller to the remaining bolt shaft that was sticking out of the timing cover. Again, 6 ft breaker bar was used and twisted it until it broke, right at the timing cover. :angryfir:

What I wound up doing was beating some small metal wedges in between the block and timing cover. After an hour of beating these wedges and prying with screwdrivers it finally came off. :cheers: I know that's not the recommended way of doing it, but at that point I was on a mission to get that cover off no matter what it took. It worked though, that cover is now on my magnum motor.

I know this doesn't help, but I just thought I would share my experience with the most stubborn timing cover bolt in history. :angel9:
