Rb20det Installing Studs

[rayj]

Hi

I'm finding conflicting information in regards to installing studs. For example, turbo to dump pipe, or exhaust manifold to block.

Prior to torquing nuts down to spec, do studs initially need to be torqued or just finger tight?

Thanks for any help.

Could of kept this in your other thread instead of creating a new one.

You'll want to secure the studs so they don't come out at all so you can use some products which will seat the studs.

Make sure you screw the short side of the stud in and have applied some product to seat the stud and screw in until you get to the center of the stud, i.e. no thread left and leave them set before putting anything together.

Can't actually remember the name of the product right now but plenty of brands like loctite and stuff produce it, just search around.

If you don't seat them or install them properly you'll end up snapping them possibly if you put too much force on the stud and then you have to start at the beginning again.

Are you suggesting the use of loctite thread locker? It will just melt on exhaust components

Put them all in by hand all the way then start the actual torqueing and stuff when your asselbling the nuts on. Dont need anything on the stud as yeah hot side its gona melt anyway, can put some graphite power on it if you want to help it not seize but dont have to.

There is high temperature varieties that can withstand some insane amounts of heat. Just need to search the right one. There is like a blue and red one, red being the better one.

But you don't need it if the studs are put in correctly.

As some sort of thread locker on the exhaust side? Have never heard or it being used before.

Thanks

Hand tight seems to be the general consensus.

So there is no need to use any thread locker on block to exhaust manifold or turbo to dump?

Anti-seize seems like a good idea though?

[breaker1845]

I haven't personally used it before but it specifies it can withstand high heat applications, turbo being listed as one.

It's called Loctite 2620, can search it and check it out, OP might be interested.

Anti-seize can be useful.

[89CAL]

2620 only does 340 degrees c. No good for turbo.

Its honestly not needed on exhaust components
