Sorry for the link not working, but, if hole is a through hole, you should use Permatex #2 on the bolt(s) for sealing the threads.

Go to: www.grainger.com and look up Helicoil R1185-6

 

Better depends on your point of view. I have TIN coated cobalt drills in all standard sizes, I don't want the drill that comes in heli coil kit.

 

Ok it is a through hole. Ill use the lock to seal the helicoil in and then use the thread seal to prevent leakage? is the blue the #2?

Also i just tried to drill this hole in a minute ago and the 12v cordless drill I have is super weak. I bought an 18v thats charging now but i dont think itll be any stronger. Would a 20v drill work at least? i dont have access to use a drill with a cord

 

Voltage is not the only factor. Drill amperage and gearing will effect this. I have seen a pretty nice upgrade from 12v to 18v but my 18 was a better drill with hi-low gearing. When I attempt to drill steel with my 18v drill I can feel it flex like the whole structure of the drill is being strained. I don;t think most of the battery operated tools are designed for working with metals. Although aluminum is much less stressful than steel.

A good strong plug in drill should be part of your tool collection unless you have a good air drill. They can be found dirt cheap at yard sales. If you can find a 1/2" GE drill from the 70's you may have to re-cord it but you would have a real drill when done. One that can hurt your wrist.

 

Yea, Buddy.

 

#2 permitex is hard setting. blue stuff is soft. use the hard setting on the coil. use soft setting on the bolt. dont want the coil coming out with the bolt.

 

man i ended up renting a solid battery drill from home depot and it did the trick. I dont know why i have such bad luck with this but i went to knock the tang off and it just kept stretching the darn coil out. I was thinking about just using a 7/16 bolt for the thread size i made and call it a day. Im pretty sure it will fit through the intake. This is all starting to add up lol Thoughts?

 

pick up another coil and do it again. this time use some dikes to cut it off.

 

All is fixed. thanks again!

 

Cool !!! Good job.
