Andy, Thanks for the advice! I did exactly as you said with the Y-pipe bolts and they came out no problem, none broken. Do you (or anybody else) know if this is safe to do for the water pump bolts. I haven't tried it yet on them because I wasn't sure about whether or not putting the flame to those bolts would damage the block around it. I have tried loosening them with a 1/4" drive ratchet to avoid snapping them, but they haven't budged. I'm quite worried about breaking one of them. Anybody have any more advice on how to approach the water pump bolts? Thanks all! Dave #5968 > > >>>> > Dave, > > I did this a few years ago.
