i was tightening down the ignition coil bolts after a spark plug replacement and number four sheared off into the valve cover.. what should i do to get it out?

also - it would not be a good idea to run the car with that bolt broken.. true or false?

 

Try a bolt extractor kit to get the broken piece out. You could drive a limited distance without a bolt on the coil if needed, I don't think it will lift up on it's own over a short distance or short period of time but you will need to bolt it down for longer term use. Don't leave it too long.

 

extraction kit cost 2 dollars and worked like a charm... thanks!

 

Good price and good work
