Any advice for applying anti-seize and loctite on the nuts/bolts/studs, etc. when replacing a turbo?

Here are the threads in question with my assumptions of what to apply:
1. turbo/muffler studs - high-temp anitseize on the nuts, any need for loctite on the studs into the turbo?
2. turbo/header bolts - nothing, I put on new stainless bolts with lockwashers
3. 4 bolts that secure the oil inlet and outlet lines on the turbo - high-temp anti-seize

Thanks, Maxx

 

Use high temp copper antisieze like Lubro Moly LM508 on all studs and bolts.

 

Thanks!

 

1) I didn't think there were lock washers on the header studs
2) Aren't the nuts supposed to be made out of some copper alloy?

 

My turbo install kit came with copper nuts for the muffler.

I added the lock washers on the header side. Why, is that bad or unnecessary?

 

Maxx,
It's my understanding that lock washers lose their spring tension as they are heated over and over again. All of the nuts on my car that were original were metric lock nuts that use slight deformation to provide the locking force. You can also make lock nuts from stainless nuts by using a metal punch and punching the nut next to the flat area by the threads.

I would stay away from stainless as it has a tendency to gall on the stud or in the threads for a bolt. Just use lots of anti-seize with the copper/alloy or what ever they are nuts.

Just my .00002

 

gall ???

Whats that ?

 

Seize!

 

Thanks Jim.

Would copper or brass nuts be better ?

 

I'm not sure of the material, but they are the stock part and Pelican has them. They are M10 exhaust nuts. They have the small slit in them to keep them tight.
