Broken Manifold Bolt Update

[55 Fargo]

Hi all, drilled out the bolt today, I marked what I thought was a dead center start, unfortunately it is off to one side, but went in straight at least.

I have phoned around to a few shops, no one wants to finish the job.

The guy who was going to come over and fix it, was not able to come out for a couple of weeks, he is so busy.

I have no idea what else to do, I have no clue how to fix this, I give up for now......................Fred

Fred, that does not look so bad. Take your biggest sized drill bit that will fit, put it in the hole, and very gently put pressure on it to the area that is left. Move it back and forth very gently and work on the material that is left and it will disappear. Once the majority is removed it is a simple pick and clean operation. I have done the same and if I go at it gently everything is OK. Notice I have used the word gently three times. If any threads are slightly damaged use a tap to get it right. Don't give up hope as you can do it and have your beast back on the road in no time!!!

As Robert says, sometimes a bit off center is not bad as long as you did not void the integrity of the threads. The thing to do now is to take a very small sharp tip chisel and gently tap the remaining sides into the center section..

or if you have an oxy acetyle set..the heating through the hole of the metal will destroy the rust between the threads and when cooled, the stud should back out very easily..If you don't heat this I would be a tad leery of inserting an easy out unless you have the real good hardened tapered square style...

Robert and Tim, I have the remainder of the bolt out, my threads were damaged on the bottom 1/3 are missing, and the hole is out of round.

I can trhead a 3/8 bolt in the hole, but it does not seal, the coolant will flow out of there like a geyser, I FFFFed up big time.

I really thought I was dead center to start, but the bolt was damaged so I goofed up, the bolt actually cut like butter, I used really cheap drill bits and none broke.

Now what do I do, drill it for a 7/16 bolt, install a heli coil, any other solution, Man I am a lousy mechanic, but that was my very first time doing that job, poverty is the mother of invension for me, otherwise I would have brought this in to a big shop in Winnipeg.

Thanx guys, I am burnt out tonight

Just invest in a helicoil set up at your local car parts store! Drill out the hole and use the drill &tap they supply and put in a halicoil per instruction on packaging. Very simple process even a cave man can figure it out! Should not cost more than 15 or 20 dollars for the whole set up. Wish I could show you how to do this but like I said before even a cave man could figure out this item. Jon:D
