ending the demon bolt once and for all

[tstkl]

so i took off all the bolts on my intake manifold and removed it except for the demon bolt. (some of you might know what im talking about, but ill simplify it to the what you need to know stuff) the demon bolt is a bolt who's head broke off while i was torqueing it down, but the bolt is still sticking out some. (the thickness of the intake manifold flange, i have a dejon smim btw.) so how can i get this out? i tried vice grips but it just smooths out the threads. (thats another thing, the whole bolt was threaded because the dealer knowingly gave me the wrong bolt. i showed them the bolt i wanted to replace and they gave me a bolt that "should work" and that bolt ended up being 2mm too long.) i dont know what else i could use short of 25 inch long vice grips that i could use c clamps on to hold it. i dont have easy out bits, and i would think that it wouldnt work so well because the bolt was too long.

maybe ill just do everything i need to do to my car and tow it to the dealer and tell them to fix the problem they created.

You have a lot of options available to you. I suggested 8mm helicoil as that's the most efficient way to do it and it brings all the holes back to stock size, not to mention every hole that is helicoiled is a lot stronger than a stock hole.

Bigger is not always better.

going to a 9mm would purely be for ease. I think im going to try the paper gasket first since i dont exactly understand what a helicoil is. also the paper gasket is 10 dollars
