Doohickey question (opinions?)

My doohickey kit arrived from Eagle Mike yesterday (Merry Christmas to me!).
I have put it off long enough, but I am going to dive in.
I have a question about the new gaskets. Actually, the question is about gasket sealants.
I have read articles and seen videos. Some say to use sealant on the new gaskets. Some say install them without anything. Some don't say one way or the other.
What say you?

Firstly if you are gentle you should be able to re-use your old gaskets. I keep a set of gaskets just in case but in the 12 or so Doohickeys I've done I've only replaced the gaskets once and that was more cause the guy bought them and wanted to use them. I think I still have his old gaskets here.

What I do, and not saying it's right, is coat the gasket with a thin layer of RTV silicone. Get some silicone on my fingers and just rub it on both sides of the gaskets. Take the time to clean any gasket material off of the cases.

Only speaking from personal experience I've done this job twice. Once with the original EM kit and another time to swap out the coil spring in favor of the torsion spring. Both times the gasket(s) were fully stuck to one side or the other and re-installed without any sealant. No leaks. YMMV.

Gray-haired riders donít get that way from pure luck.

Good point. If the gasket stays fully stuck to one case or another then don't disturb it. In my case the gasket was loose in places so I just removed it, cleaned and reinstalled with RTV.

The gaskets I received with my Doo kit from EM appear to be graphite based as opposed to the old style paper gaskets. The graphite gaskets require no sealant but are EASILY damaged. I put a light coating of copper coat on the cover to help prevent the gasket from sticking, making future removal and reuse more likely.

I think the OEM gaskets are graphite based too.

Personally, It is New gaskets every time. And just a very thin coating of RTV silicone on both sides of alternator wire area of the Outer Gasket only.

I don't want Any Silicone Worms, anywhere, in any engine, I work on.

I don't use RTV silicone on the Valve Cover 'eyeballs' / 'half-moons', either.
Never had a weep or leak from either area, to have to Re-do.
