Just remember anti seize has sand in it
I use it on tires as well

loctite should be banned from the planet! -- IF ya ever tried to take out a bolt that had that crap put on it you would know why!!!!
The red Loctite has it's place and it states in the literature it will require heat to loosen the parts. Trouble is latest generations have as much trouble reading and comprehending english, as they do speaking chinese, so don't bother with the attempt and the product is blamed when it is inappropriately used in an application. The blue, and the green are the most versatile of the products for general usage.Red, yes. Blue, not so much. Did the undercarriage on my 1150 a few years ago. Blue loctite on mostly all the fasteners. Only ones that were trouble were the ones that didn't have it. All roller bolts spun out with the 1/2" Milwaukee.
I'm a believer in the blue loctite in those applications.
Last summer I attended a Permatex seminar. I learned that for high vibration applications the orange Permatex is the ticket. It has the same strength as the blue, but should it see shock, it is still resists unthreading. Once the blue cracks loose, it does not resist unthreading. I used it for te first time recently on flywheel bolts.Red, yes. Blue, not so much.
Those 3406 manifold bolts seem to need all they help they can always seems a few are brokenMight be a little off-topic but longer bolts with spacers can be very good and even essential in many applications! The thing to keep in mind is that in many applications(if not all) what helps keep things fastened securely is the spring effect of a bolt stretching as it is tightened. This is where longer bolts can be very beneficial.
Just think of a coil spring that is only 1 inch long compared to one 3 inches long. The three inch bolt would have to stretch three times as much as the one inch bolt before either exceed their elastic limits.
One example I know of is the exhaust manifold studs on a 3400 Cat. Ones I thinking of are only 3/8 inch studs going through about a 1/2 inch thick flange. Those studs are something around 3 inches long. If you tried replacing the studs and spacers with say 1 inch bolts I would be surprised if you didn't have them breaking in a short amount of time.
One problem I could see would be using longer bolts but ones with only a minimum amount of threads as that would put the majority of the stretching right where the threads start. One reason in some cases they use bolts with reduced shanks to allow them to stretch over a longer distance. You can see that theory being used in places like say rod bolts on many engines for one.
That's another reason I used the Nord Lock washers. Because the bolts were very short I figured they wouldn't have the built in torque/twist a longer shank bolt would have and could come loose easier. They're working great so far, knock on wood.Might be a little off-topic but longer bolts with spacers can be very good and even essential in many applications!
