Must be a Harbor Freight special?

I was confused when Charlie said the torque was supposed to be 89 in-lbs and that is why it broke.

I think he missed that he bought an inch torque wrench and had the other already.

I wonder if the broken bolt can be sent to me. I'd like to do a hardness test on it. I have the ability to do a standard rockwell test in it, as well as a micro-harness test.
Well, if I ever use my stainless fasteners Charlie sent me I guess I could do my own. However, I didn't break any of mine.

Harbor Freight exactly. Went to all the local hardware stores and automotive and found nothing in inch lbs. Probably could have gone to Sears I guess. It was a combo of a poor tool and operator. Damn box said it would click, and it doesn't (my ft lb yells at me). I was paying more attention with my ears than the feel of the wrench. Live and learn.

If you want the stripped bolts, shoot me a PM and I can send them both to you (or 1 if that's all you need).

I missed that and thought you torqued to 44 FT lbs. Inch Lbs are tricky. If you dont use a smooth range of motion you can go right by it and if the bolts are weak they will break.

Ok so Mike got one bolt out...couldn't get at the other one because the drill bit wouldn't bite into the center of the bolt...any other crazy ideas before I have the engine ripped apart?

can you see any of the bolt with the intake off?

Well not an idea about getting the bolts out. If the drill won't bite into that bolt it leads me to believe they are not case hardened, but heat treated through. To break one it must be pretty hard.
Anyway, the bracket in the back is actually a safety device for the fuel rail in case of a front end collision. A Risk perhaps not to have it..........

BTW, an EDM is the only other way to get the bolt out.

If the drill bit is just walking across the face of the break, you could try lowering a hollow sleeve into the bolt hole. Run the drill bit down thru a hole in the centre of the sleeve.
Also if using a right hand twist drill bit, swap to a left hand twist (and vice versa).
