I need a little education on this. I am doing some mods to the bike. Arlen Ness Big Sucker SS stage 2, PC-V, torque cones, and samson custom shop step true duals. The question is can I use the blue removable thread locker to keep O2 sensor plugs in?

 

Somebody correct me if I'm wrong but I believe the answer is no. The operating temperature for blue loctite is -65F to 300F and the exhaust will get much hotter than that. Just tighten it real good and it shouldn't go anywhere.

 

You're right. The high temp/high strength is good for 450 degrees. I wouldn't use anything either. If you expect you might want to remove the plugs someday I'd put antiseize thread sealant on them.

 

antiseize +1

 

Neverseize = removable!

 

Antisieze only!! anything else and they won't come out. Well with the threads intact

 

No need for LocTite. Anti seize for sure.

 

I used the copper based anti seize. I had a can laying around. It is good for higher temp than the nickle based stuff but both will work.

 

if you dont want to remove the plugs later just insert them with nothing and they will stay

 

thanks all. I happen to have some.
