Ok peeps, Either a miracle happened to me today or severe disaster struck, you help me determine...

So I kept drilling for one last hour today, just 2 min before I decided to finally give up... , the drill started acting weird, and shards of metal started shredding off the bit a such a rate that I thought that either the drill bit overheated and started disintegrating or that I bypassed the bolt and started shredding the aluminum head. When I pulled the drill out, a large hole had formed, so I drilled for no more than 10 seconds, (no exaggeration) and I went in a least 3 centimeters, almost the length of the bolt. It was like drilling through wood.

I'm posting 2 pics, you tell me if it looks as if I bypassed the bolt or not. I was drilling at the right angle and it really does look like I drilled through the bolt. But I can't see how the bolt would of decided to start disintegrating at such alarming rate after being impenetrable for so long. It really felt as if I was drilling through soft metal like aluminum.

My problem is that IF it is the bolt i went through, I was using a bit too large to fit an extractor or left handed drill bit. So I can't try any extraction method right now to verify.

But again, tell me, it does look like i actually drilled through the bolt right?

If it was me I would go buy the heli coil that you will need and check the instructions for the correct size drill bit. Drill it out to the recommended size insert heli coil. Done!

You know, that was my plan all along in the case I ruined my threads. But after looking at the price for a heli-coil...HOLLLLLY SHIIIITTEE! They're about 55$ (Canadian funds) for a set of 10. I thought you could just buy the coils, bits and accessories separately. I would of bought the tools and a few coils of different sizes for later. Unfortunately all you can do is buy one set of 10 coils with tools...but all I need is ONE.

So I'm wondering if I should simply get a tap and dye set, re-thread to a bigger diameter and use a bigger bolt. The headers themselves have holes large enough to support bigger bolts.

What would you guys go for?

The aluminum is soft so the threads could strip again also you would have to go to a larger size bolt as well. Heli coils are steal and bite into the aluminum alowwing you to use the same size bolt and a stronger thread. My buddy who is an AP uses them to put airplanes together.

I've never had a problem using heli-coils, that's what I'd do if it were me. If you're running out of dough though, the bigger bolt is the cheaper route.

Well... I finally got that SOB out. Post a pic tonight. Turns out that the threads are mint. Only the screw was taking damage. So now I'm about to lift the truck back up to install the headers.

I can't seem to find the Torque specs for bolt installation though. Can anyone tell me what the torque specs are for the headers to the heads? Thanks.

Not being a dick, but is it really necc to tq them to spec.. Use good judgement, like tight but not ringing the heads off tight.. LOL Start from the center and work out, tight on the first pass then one more time CONGRATS on getting it done, finally
