Well to anyone interested, I found out why I broke 3 head bolts.

I'll just leave this right here. Hint: check spec section. The giveaway is the thread starting depth.

For those who didn't want to look it up, my block is early 1999 but my truck is a '96. Instead of a 2 step process, it is a 5 step process. Coming nowhere close to 70 ft. lbs. How the passenger side worked is beyond me.

I'm working on it today. Had to get some 1/2" tubing and grind to fit for a drill guide. Slow going, but this should help
me drill straight at least

In theory, theory and practice are the same. In practice, they are different.
Heaps and heaps of good luck to you.

are you using a reverse twist drill bit?


No. The left handed bits aren't strong enough. The bit in the picture above is titanium and barely makes a dent. Got a cobalt bit at Grainger last night and went through the bolt like it was butter.

That sounds like progress
