    Stubborn plug screws

    any tips on removing these plugs, usually an oxy on the block works or smashing an oversized torx bit in but these bastards have snapped 1 torx bit, twisted another and snapped my easy out tried locktite freeze spray on the plug and a rattle gun but she's not budging .

    A hammer and screw driver works good, chisel out a little notch then tap away, they break free pretty quickly

    Think I'm going to have to drill and crack them out never had ones so tight before. The easy out would just b tightening one but I'm going for the air chisel now

    I used an air chisel and broke them loose. I also welded a nut to the plug and unscrewed it.

    Did you apply lots of heat? You really need to get it near smoking to break the bond of the yellow 3M crap (or even red loctite from the previous owner that didn't know better)

    Also, I think an air chisel is not the best tool to get it moving, only use it for making the cut. Use the air chisel to cut vertically first, then use a blunt chisel (preferably square faced) with hammer from that point forward. A sharp air chisel will do nothing but shave aluminum chips.

    After I experienced one like you have, I decided from that point forward to heat the shit out of the plugs before even trying the torx bits, use a good quality torx bit (Snap-on), and beat the torx bit in first before trying to apply torque.

    Don't know why they use that yellow crap. It doesn't set hard like Loctite, but makes it pretty hard to darn impossible to remove some of those plugs.

    Pretty hot with a propane torch until it smokes and has a funky mustard like smell, that's the yellow stuff getting soft. Then unscrew them.

    It's been rebuilt before so won't b stock yellow thread locker, I'll try the oxy torch again. Block has broken the chain guide support so is toast anyway. Thanks
