threadlockers, remove it or leave it?

[dongoesby]

I've read mixed reviews on the high temp/ max strength treadlocker and decided to put them on when I reassemply my SR motor.

I've put them on all the bolts that go into the block like p/s, alternator and a/c bracket, motor mount, etc. More importantly, I put few drops on the exhaust manifold studs that go into the head as well as the manifold nuts.

Recently I found out that they are only good for up to 300 C and will gunk up the thread of studs. I'm very concern about this whether to leave it be or completely remove them. If so, how?

torch and vice grips?

I know heat is the only way to get it out. But should I remove them? because I know it would be a hell of a job. And they are seated perfectly now.

I called Ray, the guy from thenismoshop, and he used threadlocker on his studs and nuts too. Should I leave it?

[Tantwoforty]

i mean... i would leave it there, but im lazy. just keep an eye on it for a while and check for any exhaust leaks from the manifold.

thanks!

anyone got more insights?

[wangan_cruiser]

never used one when i was reassembling my sr.



torquing down should be ok.

yeah...

they didn't use it in the sr20det assembly plant did they?

[wangan_cruiser]

yea i dont think so


u dont want to over torque


keep in mind that sr20's are aluminum easy to strip a thread.

yes i've followed each step of what the fsm said (35 ft/lb). But to add as an insurance, I put threadlocker on both ends of the exhaust manifold studs. And now I realize that it might be a problem.

i dont think u really need a threadlocker


but im thinking u probably meant the stud that connects the turbo and manifold


just get the locking tab

no, you have got this all wrong. I have put threadlockers on my bolts and studs that go into the block and head (a/c bracket bolt to the block and ex manifold stud to the head). And I'm now know that threadlocker might create a problem, so I'm thinking either to remove them completely or leave it.

I'm running stock boost and tomei manifold and 7 layer gasket.

The only places you need threadlocker for is the flywheel bolts and diff bolts. You actually want to use anti-sieze on all the block and head bolts, to prevent galling and potentially stripping threaded holes in the block and head...

[weissguy]

jeebus. dude, you will be fine leaving the threadlock on there. Your bolt/stud is going to stay put whether you have it on there or not. Don't waste your time, just leave the thread lock on there.

[burninskulls0911]

i would rather it be hard to get out than fall out

[projectRDM]

The block bolts aren't a problem, they'll come out if needed and stay put otherwise. The exhaust bolts though, it will just burn off eventually. They may come loose, may not, but the threadlocker itself will fail. I always tack weld a tiny spot on exhaust hardware, like the turbo elbow or turbo to manifold nuts, you can break it easily if needed but if not they're not going anywhere. Ever.

Thanks, that is a great tip here.

But nonetheless, as the question has yet to be answered clearly, is it safe to leave the Threadlocker melt on the ext manifold studs?

[wangan_cruiser]

it should be safe man. just torque them by specs
