Is my bottom end left seal bad?

I was just going to cut a wrench in half that fits on the bolt then weld a socket onto it and put the torque at 18 instead of 20 pounds because it would have more leverage.

Sears or good auto parts. There is a formula for knowing exactly what the new torque value would be.
If some one doesn't chime in with it, try Google
 
If you have seen kens videos, he made himself a crows foot just for the blaster. i believe he tensioned it to 15-16 after some math
