Broke off tap in head......crap

While installing my new aluminum valve cover I bottomed out a tap in the unthreaded holes in the head and broke it off about 1/4 below the surface. Anyone have any ideas or tricks for removal????

Are you sure you're from Luck? Wish I could help you, but all I have is sympathy. I busted a main cap bolt in the block while changing out my rear main seal last year. Fumed for about a week before I got a reverse bit, EZ-out, and a six pack. Started with the reverse bit and the darn thing was loose the whole time. Spun it out with my pinky finger.

Just keep in mind: things are never as bad as they seem. These are jeeps, built by man and any problems you come across can be solved by man - even you! Best of luck.

Try using 2 pin punches in the openings in the tap as a handle to back it out. You can put a wrench on the 2 punches to help turn them. If that doesn't work, use one of the pin punches to drive it around and back it out. Use plenty of lube. Good luck.

I have used removers similar to these with better than average results:

Damn that sucks. Your tapping threads for a valve cover so it's probably a really small tap. Try fitting some thin needle nose pliers into the "tap openings" then twist it out with pliers?

I tell myself that every time I muck something up. Which happens with some frequency. Yet somehow she still starts up in the morning.

Success!!!!!

Thanks everyone for the replies, I got it out. Ended up using a Snap-on "pencil" grinder (I think thats what its called I borrowed it..) with a small bit that looked like an end mill. I was able to grind out the middle and then break it up with a punch, picked out the pieces with a pick and a magnet. It took about an hour of grinding and swearing to get it out. Wow will I be more careful...........
