So I noticed last night there’s some sort of liquid coming out from the valve cover gasket doesn’t look like oil when it dries up it turns white I’ve noticed the white material before but I thought it’s soap from washing but know i know its not Does anyone have any idea what it can be?

That's plasticiser coming from the rubber. As the compound leaches out the rubber gets slightly stiffer.

Nothing to worry about, it will slow down over time - just keep wiping it off.

Had it with tubing in my water-cooled pc.

Honda do recommend the seal is replaced when valves are done... Most likely to counter the natural hardening of the rubber.

Yeah, mine does this as well. I actually had a different question, if I touch the valve covers on the right side of my engine, they feel tight like they don’t move. However on the left side of my engine, they have more play. Is this normal?
