Topic: Oil pan gasket, etc

[emlupi]

Good day all,
My oil pan gasket is weeping so I am going to change it. Is it necessary (or advised) to use a sealant along with the new gasket when installing it? Or, is it better to use the gasket without any sealant? What is the preferred method?
Also, I have to change the shifter shaft seal for the same reason. Can this be done without removing the cover and, if so, what is the best method for removal? Appreciate any help with these items. Thanks

I always wet it with oil, and let it set for an hour or so, then wipe off the excess.
All pan hex bolt threads are coated with ARP thread sealant, and hand tightened.
I have zero leaks from my pan gasket.

The shifter shaft seal is easiest to change with the side cover off, but yes, you can pick it out.
Have a rag handy for the little to no oil that may drip out if you remove the cover.

I use the sealant without any gasket on the oil pan, works for me.

I can see this being nearly impossible for on-bike maintenance though...I don't know how you could possibly clean the upper mating surface well enough for gasketless with all the oil dripping down.

I first done it on Dana 44 axle on my jeep, just did not have a gasket and it worked fine.

On CB750 I clean the surface several times, the oil eventually stops dripping and surface can be degreased.

I spread the sealant on the pan only using a small knife, just like buttering bread.  Typically wait till next day to pour oil in - if I have the time - to give the sealant time to cure.

Std gasket and tighten all bolts with 10Nm (7.4 ft lbs) No leak. I tighten all M6 bolts with that torque. Allen or hex only. All OEM X-bolts replaced

I had a weeping oil pan when I used a Vesrash Gasket. Switched to OEM with no sealant and it's dry as a bone. Since Honda didn't use any sealant I say none is needed.

 I like to put a thin film of non hardening like Permatex 2 on the engine covers side then place and press the gasket in place so it does not shift during installation and hopefully the gasket comes back off with the cover if I have to go back in some time in the future.

No sealant, dry gasket on my 750. I've used two or three gaskets over the years, various brands, all dry and no sealant, never had a leak or weep once.

I replaced my shifter seal just by picking it out. I think I used a long socket or something to press it in after I oiled it up if memory serves me.

Thanks for the replies. I already have an OEM replacement gasket. Didn't know whether it was necessary to use a little sealant for insurance or not. It seems that the conventional wisdom is, "if the factory didn't use it, it's probably not necessary."
