Why is it that when you install a screw-on oil filter they tell you to lube the gasket with oil, and when you install a valve cover gasket they tell you the gasket surface has to be free from oil?

Lubing the filter gasket makes it easier to unscrew later, on cartridge filer caps it allows easier seating of the cap .

Be use the filter seal needs oil to lube the seal as itís scrubbing against the oil filter sealing area while itís turning to be tightened.
The valve cover gasket doesnít need oil because it being tightened down in one direction

It has been my experience that sooner or later...valve cover gaskets oil themselves!

Because your not spinning the valvecover 3/4 turn after the seal contacts the base.

Where is there more friction?

Why does the valve cover need to be clean of oil if the filter seals with oil on it?

Lets say we don't need to apply any silicone when replacing it. Which they generally don't at the factory anyways.

Oil filter is torqued somewhat tighter.
