Changing the intake seals on my 93, noticed that there wasn't any anti-seize on the cap screw threads. I know that these the seals have been replace at least three times since new: (2 top ends, one leak). The last time they were done was in 2006.
Would putting a bit on anti-seize on the threads be okay? Or should they just be put in dry?
Reason for the replacement is a recent, rough idle, and occasional miss at 75mph. Going for parts today.
Thanks. That's what I was thinking. Obviously the last three 'professional' wrenches, thought different.

Usually nobody would put anti-sieze on these bolts because they don't need it....if it was an Outboard motor then every thread would need it but its nice and warm and dry in by the intake manifold and H-D use good quality fastenings...I have never had to remove a snapped off bolt that had siezed itself in on a Harley....plenty of times on Jappers back in the day but in this instance you don't need to do it.....H-D put the opposite (Loctite) on many bolts....there is a reason for this ;-)
BTW......."professional" wrenches often know more than internet Trolls

I'm sure there are professionals that take pride in their work. Somewhere. They just haven't worked on my bike lately. Which is why I'm asking. And last time I looked, I didn't live anywhere near a bridge.

Any reasons (other than what Spanners39 posted)? The one's I removed had noticeable corrosion on them.
Not putting anti-sieze on bolts that don't need it has nothing to do with pride in one's work.......Those particular bolts don't wanna be coming loose on you or you could blow the motor because it might lean out and fry the pistons. Not putting anti-sieze on certain bolts just means its being done according to how H-D make them and what the Factory Manual tells you to do.
Its like lifter block bolts...they are a **** to get out and that is because the manufacturer wants them to stay tight...bear in mind that these mnotors vibrate a lot, you can't feel it because of the rubber motor mounts but certain parts of an Evo motor could possibly shake themselves loose if the bolts were not put in dry or loctited.
As for Trolls.....I wasn't necessarily referring to you but you sometimes get people on these forums who chime in with an opinion that may seem like perfect sense to the layman but to the "professional" its hogwash and not based on a sound knowledge of working on Harleys....its good that people are enthusiastic about helping others with their bikes but you have to be able to distinguish fact from fiction and this is true of all the internet-based knowledge....regardless of the subject.....spend some time on Aviation Forums if you want some examples :-)

Those particular bolts are coated/plated when new and don't require anti-seize.
If you are seeing some corrosion, the plating could be wearing off. You can either replace the bolts with some OEM pcs, or apply a light coat of anti-seize to prevent any dissimilar metal adhesion down the road. Just my opinion.
