In each of two attempts I've broken one of the water pump quarter inch bolts. Different holes. Fortunately it's in the timing chain housing and the first (just broke the second today) was easily removed by a local machine shop. The second attempt I tried to do everything super hygienic, cleaning out the bolt holes, using anti seize and I really didn't think I was torquing it too much, and yet.

What is the recommended torque????

Feeling a bit like Sisyphus at this point...oh, doesn't look like I'm the first on this engine I've owned for 32 years as a couple of the holes already look like they've been helicoiled, pre 1987
