Thread: valve cover bolt broke in head... best way to remove?

Tweet

a very sharp center punch and hit them on center drill and ezout

i tried that on one and it just did not want to stay centered... im thinking about drilling it out and and using some heli coils

heli coils would work on valve covers, they dont require much torque...... sounds like the guy WAY overtightened those bolts... they only need to be hand tight

yeah man i dont know 3 out of 4 bolts?lol
oh well i had like 6 punches from 3 garages and none of em would work...

theyre just like the regular bolts for the centerbolt valvecovers

I'm like you, I've never had great results with EZ outs. I have a hard time getting the drilled hole dead center.

What I have done sometimes is to centerpunch it like Pat and the others said, but then use a very tiny drill bit to do the first hole, then move up from there. I have never used the left handed bits, but our Techs have, and like them.

By the way, the gold drill bits that Harbor Freight sells are awesome. They put sets of them on sale all the time, and I find them to be very sharp and they stay that way for a long time. It is one of the better deals at HF.
