When you Loctite the rotor screws, use ONLY Green Loctite. Its called "stud and bearing mount". Dont use red, dont use blue...use GREEN.

Had a buddy with a MSD Opti loctite his with red and the screws still came out.

I have been using green and have yet to have one come out.

 

where u find green at ?

 

Which formula, 290 or 294? 294 is also heat rated to 450* so that'd be my choice. I see that a lot of the red compunds are listed as applicable to fasteners larger than 1/4"

Although the red stick might be just as good "this high strength threadlocker is better suited for heavy-duty applications where resistance to heavy shock, vibration, and stress levels is required. Localized heating and hand tools are required to separate parts."

 

USE GREEN, nothing other than green. I dont know what formula it is I know it as "Stud and Bearing mount". I think any green will work as long as its Loctite brand.

I am telling you guys what has worked for me. I have 9000 HARD miles on my car without one opti problem.

I have a GM opti, only mod is the rotor screws Loctite'd with Green Loctite.

 

Damn, everyone keeps talking about using loc-tite on the rotor screws.. I didn't use ANYTHING when I put this opti in 3 years ago, and my heap is holding up. In hindsight, it would have been a great idea to do for some peace of mind. Definitely doing this next time around..

 

I have removed red loktited screws that were used for years and they were on the verge of stripping the heads but they did break loose without damage. Aint no way those dude were gonna loosen up. Never had a problem with red here.

 

Something happened with his. The correct formulation of red should not have came loose. There are a TON of "red" loctite tho. It's possible he got something off the wall like hydraulic thread sealant.

Or he got the permatex brand, because it is JUNK

 

Exactly. Reads like 'teh vodoo gonna git u' if green isn't used.

 

permatex brand is good for rtv silicon

 

I actually did strip one of the heads with red loctite. If the screws came lose with red loctite it was install error.

 

Say what you want smart ***, you get Loctite GREEN you got what you need. My Opti is still kickin, its had the crap beat out of it.


You do what ya want.

 

What you state sounds just like what a service writer would spew. It's ignorant horse ****. Red loc-tite works just fine. You make it read like if you don't use "GREEN" you are doomed. Hooey.
Fantastic. I have two optis. The original where the screws backed out, red loc-tite was used and it held just fine for another 70,000 miles before I removed it. Still works and is a spare. The one I have now on the engine has no loc-tite. I WONDER if it is GOING to LIVE?

Absofreakinglutely.

 

I have seen two come out with red on them, both guys knew what they were doing.


I'm just sayin

 

Mine had NO loctite and is fine for 8,000mi *knock on wood*

Dave what's the actual number of the one you used. And the ones that failed if available.

 

I keep hearing about loctite on the rotor screws, my original opti went 100k with no problems, and 10k on replacement with no loctite. Am I just lucky?

 

I thought loctite in general is supposed to be used on metal to metal stuff but if you say its doing the job on plastics, more power to'em. The green type is actually the "wicking" type intended for being applied to nuts and bolts that are already tight. As in, you drip it on the threads and it will find its way in there and then harden up. If you dont have a hardware place around town with the green.. just google it and buy a bottle or two online.

 

No loctite on mine....been doing just fine..

This is what you get when you give good advice on this forum. I have a 15 year old Opti in my Firebird that sees high RPM's on every pass. It hasn't lasted that long because I got lucky!

 

For you guys that have loctited the screws, but need to take them out for some reason; heat the screws with a soldering gun (240w version) before you try to get them out and you'll save the screw heads. You'll melt plastic, though, so be prepared.

 

Used Red on my Z28 before I sold it. Few thousand miles with no issues. I've never had a single issue with the red failing on anything I've used it on.
