lubricant/dressing for o-rings

What do you put on the intake port o-rings and manifold to blower o-ring? Or do you leave them dry?

white lithium grease

Ditto on the White Lithium Grease.

 

Just buy a can of white grease and it should last a few years. We use it on the intake and end seals. Oil pan, Valve cove gaskets on the fuel car. Things come apart and go back together nice

 

I will bring you a few cans when I come up to lite her off. Just remind me

 

Thanks for the input everyone.

 

Mac's silicone spray from NAPA stores part # 8300
Leaves no messy film to clean up, preserves the o-rings and keeps them from sticking.
This stuff sprayed on gaskets makes them non stick too.
Will not color your spark plugs or cause detonation like white grease or the o-ring lube used for transmission overhauls ect..
Not for use with oxygen sensors.
