    Broke a Tap Off Cleaning Threads on the Low Pressure Oil Pump

    I was cleaning locktite out of the threads on the low pressure oil tower and the tap snapped off in a bolt hole ( one of the small ones ). Crap! It's brittle, but very hard. I can't seem to drill it out because it is so hard versus the case. I broke it out to about 1/8" below the surface. Any ideas? I have thought about leaving it out, but that is not my nature.

    Maybe an EZ-out can back it out enough for you to get a hold of it with a pair of vise grips to pull it out.

    Nope, nope. Expensive tap, but small diameter one. Only thing I can think of it to try to dremel the hardened steel out some how and then helicoil...............

    Yep, thats it. Really brittle I guess. It snapped easy, but it is wedged tight. Not in my nature to not install the screw. Really sucks, I coulda dropped it in the hull today.

    More than once I have been fortunate enough to drill them out. Just start with a very small bit in the center and work your way up.
