    The pump head on my father-in-law's power washer has a hairline crack along the threads on part of the pump that is causing it to leak/spray like crazy. I believe he over torqued the bolt. I have clearer images, but the photo gallery is not cooperating, so hopefully the little ones will work. Aside from spending $150 on a new pump, has anyone repaired something like this? I'm thinking JB Weld, but figured to see if anyone has done it successfully already. The pump head looks to be cast aluminum. Thanks!

    Before replacing the pump... I would give JB Weld a shot.

    The crack has allowed the bolt hole to become oblong.

    JB Weld the crack... Thread the bolt back in while it's still flexible and put a small C-clamp on it to pull the crack closed around the bolt.

    If it still leaks.... I think you're looking at a new pump.

    Let the JB-Weld harden a full day before you put water pressure to it.

    Good Luck!

    I dought JBW will take the torque unless you helicoil it after. I would aluminum weld it and retap.
