im thinking about helicoiling the top 2 holes in the block, where the tranny bolts go into the block. i was wondering if anyone has ever did this before. im pretty sure the hole is 12mm X 1.25 thread pitch. the only helicoil inserts i can find are 18mm deep, and i was wondering if they would be deep enough? (this is on a b18)

 

no helicoil help?

 

Ok I'll admit I've not helicoiled that before, so take this for what it's worth. I'd take the original bolt, measure the length, and subtract the width of the tranny piece so you know how deep you need. Then try to find a helicoil that fits, sounds like you have the width and thread pitch down, so just try to match the length. You might have to go to a specialty nut and bolt shop. Then tap it and try to put the helicoil in like you normally would. I'm assuming it's all stripped anyways and you're not just trying to put in a larger bolt, so you probably don't have much to lose.

 

can someone explain to me how a helicoil works? i know its repairs a striped hole, im just sure on the mechanics of it. how does it work? how does it stay in? any install guides?

 

its basically a sleeve with threads on each side, the outer threads cut into the new hole and the inner threads is where the new bolt will thread in, its really simple, so you should have no problem with it. good luck.

 

thanks man!

you know of anywhere online offering helicoil in the size i need? the only ones i could find are 12mm X 1.25 X 18mm (lenght)

go to napa they should have everything you need.

 

anywhere online that sells tools should have it, a google search should do the trick but i think a local store would be a much better option, you just gotta look
