So Im changing my head gasket and go to tighten the head when the last stud Im tightening feels weird. I pull it up and a helicoil comes up with it......great. And the outside of the helicoil was stripped. What do I do now? Ive been looking online and the only thing ive seen is the big sert helicoil repairer.

Go to the auto store, get a helicoil kit. Put in a new helicoil and thread bolt. It is very easy to use, and means that the threads are stripped in that hole if you didnt know. It is a simple and cheap fix.

Going to call the vendor for you in the morning... Holiday weekend could not reach anyone. Haven't gave up yet We can order them in the 11x1.25 from what I saw

Is the inside or the outside of the helicoil stripped? You can probably get away with running one size up on the helicoil, and run a big bolt if the outside is stripped. If the inside is stripped, you can probably swap it for another same sized one. Im not 100% sure since i dont see pictures of the coil. If I saw what youre talking about, i can tell you for sure man. Feel free to pm me if i dont get back to you on this post.

Only the outside of the helicoil was stripped. The inside was fine.

See if a time-cert works for your case. If not you'll need it welded/re drilled/retapped/re-time-certed.

Two helicoils? idk.

worr20 · 07-08-2013, 10:11 AM

Thanks codyace. Ended up ordering a bigsert kit. Wish me luck. lol

Ok just to give an update. The bigsert kit was too big. I returned it and got the 2200 toyota kit. I can say its well worth the 415 bucks. It was so easy to do. I would recommend this kit to anyone that has to re-tap a block. Thanks again CodyAce!!
