Never heard of torque to yeild bolts. Did a little research on them. They are used a lot now on head bolts and body applications. If the WP bolts are torque to yield type the problem may well be them. TTY bolts are only supposed to be used once, then they start stretching and losing holding power. I think I'll get some new bolts for that pump before I blow $500.00. They might just do the trick. It doesn't seem to be leaking from the weep hole or shaft, seems to be coming from the gasket. Hopefully I didn't torque them to the breaking point when I retightened them. Only thing I question about this theory is why would it not leak for a week, then start dripping?
