I think spoolin or go autoworks has copper lock nuts that work quite well..

If those dont work, your next step is Stage 8 locking fasteners

How do you think you are supposed to properly remove a "Loctite"d fastener? With heat... Soo, that idea won't work. Yikes.

Lock washers or serrated nuts. I use grade 10.9 fasteners and torque them. M10 to 40 ft-lbs. M12 to 60ft-lbs.

Either:

ARP 3/8"-16 stainless bolts with red loctite.

or

High-strength studs and nuts with red loctite.

I am currently running Full-race studs and nuts on my setup with no loctite, I even have anti-seize on the section of threads that are in the manifold flange.

no issues or leaks.

best advice is to check the bolts and/or studs after 3-4 heat cycles and re-torque if necessary.

I hate to say it, but the full-race studs sucks heat and vibration from solid mount snapped mines I guess, I am currently using ARP exhaust studs.

I've always wanted to try this on manifold/turbo bolts. I've done this on roller coaster brake systems with special tools but I can be done with basic pair of pliers. You'll find videos on youtube on how to do this.

Not sure if the heat will anneal the safety wire though.





Whatever you decide to do, buy high grade made-in-the-usa hardware.

Always had a lot of trouble with my bolts walking out over time as well. Never used lock washers though. Crappy ebay manifold inhibited my ability to fit much in there. I used to just check the bolts once a week since I was always fiddlin' around with somethin anyway.

Buy good parts!

ATP studs and locknuts. A lock washer isn't going to do anything and neither is loctite. The heat just relaxes them. You would need a star washer and proper nuts if you were going to try that route and the nuts are usually rather large.

IF it works with lock washers and loctite it would have worked without them.

We used these on exhaust of racing carts. You had to because you had a restricter plate bolted between the engine and the exhaust. The officials would crimp your wire with a special tag to make sure you didn't remove the plate in between races. There where different plates for different classes.

This guy speaks the truth. I have lock washers on mine, but if you ever take them off after plenty of heat cycles, you'll see that they are completely flat.
