The threads on my engine block drain plugs have karoaded till i can't replace the anti knock sensor on the right side. I tried a tap but the crap is hard as a rock. Any suggestions?

    Dude, call Super Dave -- he fixed his.

    You probably are using the wrong tap.

    Use anti-seize on them when fixed

    Dave thinks it was 1/8th pipe thread

    If its just corrosion, try something like Lime-Away. But yes it is pipe thread.

    it should be 1/4 pipe thread, use a sharp tap (not an old worn out one) and a little thread cutting oil
