    Snapped engine mounting bolt

    Hello
    Just wondering if anyone has had a lower engine mounting bolt snap? Discovered mine was snapped after a short ride as it was literally sticking out. Now problem is other half of bolt is stuck in the engine casing.

    Any help or advice would be appreciated

    EasyOuts or similar should help you remove the old bolt.

    Yes tried that and part of the easy out broke inside the bolt. Now bolt and easyout have to come out. I believe since bolt is steel and engine case is aluminium the bolt is seized inside

    Broken ez-out? Sucks! Two choices that I see.

    1. Try to get the remains of the ez-out out with a punch, drill the bolt out, and chase the threads with a tap or install a helicoil/timesert if the treads are too damaged.

    2. Alum. Yep, the stuff in your mama's spice rack. Aluminum sulfate will dissolve all of the steel, but not touch the aluminum.

    Make a well/reservoir around the area out of aluminum foil or a soda can and seal with RTV or something so it can keep the area submerged under liquid. Mix the alum with water and fill the well with the solution. In a day or two, the steel bolt and ez-out will be dissolved. It works MUCH better if you can keep the area heated. Incandescent bulbs work well for a heat source.

    I don't think it will hurt the engine paint, but I am not 100% sure about that. Test in a hidden area just in case.

    I'm not sure which bolt you are working on or if it's even accessible enough to use that method, though.

    Good luck!
