Red Loctite?

[nike001]

Since I did my VANOS about 6 months back, I've had a stripped thread for one of the holes that are in the head. Here is a pic of the hole with the stripped threads inside:





Now, my question is.. can I use red loctite and put it on the threads of the stud and then place it in the hole? Ever since my VANOS job, I've put in and lost at least 2 studs. But they would thread in, and at some point while tightening the bolt on the end.. the whole thing would spin.

Terra said red loctite would work, but others that I've talked to said that I need to completely re-tap it and get a bigger stud. I'm iffy on that since the threads are in the HEAD of my engine, and I don't want to ruin that just yet.

I'm no pro, and I know nothing about red loctite. That said, I'm gonna go ahead and posit that you'd need to re-tap that baby. Plus, I don't think it'd be too difficult.

No flavor of Loctite is gong to work if the threads are stripped. I can't quite tell what that stud does from the picture, do you know what the torque spec is for it? If it's not too much you could use a Helicoil, they are available almost anywhere:

If that happened to someone that was in the middle of nowhere they might smear it with JB Quick and put it back in. Depending on the torque it might not work at all, or it might last forever lol.

cool, never heard of the helicoil...

The stud threads into the head, and then the bolt tightens onto that, and if I copied the right specs.. the torque is 10 Nm (7 Ft-lb), so not much.

I have JB weld, think that would work?

Are you talking about putting it on the thread to hold the bolt tight with JB Weld? It might work but I'd try to avoid it. I've used red loctite on a suspension component before- try and clean out the thread as best you can with degreaser and a Q tip or it'll have issues bonding. At least that is at some level removable (blow torch).

Have you tried a simple tap and die set? You can rent it at your local autozone.

[nike001]

No I haven't tried tap and die. To be honest, I have absolutely no clue about tapping and all of these different sets. This is something I don't know how to do and I want a 100% change of me not messing this up

[zhp43867]

The tap and die set is a kit, with clearly labeled threads of all different sizes. Based on the nut that screws on to the stud or realoem, you determine the thread pitch. A tap and die is just a really strong screw/nut with areas to capture metal shavings it creates by repairing the original thread. I used it on a seat bolt and it worked quite well.

Alright, I'll look into it. Maybe Terra will be home this week and can lend me a helping hand.

Lol. I bought and used one specifically for my seat as well.

@ Nike.... You can do this.
