can this be done?  can i use Lithium grease or does it have to be dialetric grease?  whats the difference?

Yes.... Even a tiny smear of Vaseline on the ID of the rubber will help with keeping them from getting stuck to the plug.

I'm glad T got to you quickly cause this could go so wrong.

I know right!  Last time I took them out I had such a bear getting back in. I put a very small dab of lithium grease on shaft and slid um back in.

And you got know complaints using garage grease instead of something more hygenic?

Haha figured somebody would go there.

 

Ah....all is right with the world...

Yeah, lightly grease them before insertion <chuckle>.

It is a good idea though. All grease is dielectric unless it contains something that conducts electricity. In fact, all pure petroleum products are excellent dielectrics unless they contain some other, conducting compounds. Silicone grease is usually used on electrical components but I often use a light coating of wheel bearing grease or chassis grease as long as it is light in color (so it does NOT contain any graphite or moly lube, etc.). Brake grease (caliper grease) is also fine for electrical use.

There is often a nearly perfect product for every job but if you had them all at hand, the garage would be full of lubricants, solvents, cleaners, etc. It is usually easier to find something that will work for a large range of jobs even if that job is not mentioned directly on the label.

Copy, thx.

Be aware that petroleum lubricants will attack certain grades of rubber and latex.

Yep, that is true and it is why you should never use petroleum jelly ("Vaseline") on a.... never mind.

Still, other than internal brake seals, it is unlikely that any vehicle manufacturer would use rubber components anywhere near an engine and / or drive train that are not greatly resistant to petroleum products that they would be likely to come into contact with. The rubber seal on a stick coil, or any other component attached to an engine, is almost certainly greatly resistant to petroleum based lubricants.
