I was told I have a cracked valve cover at cap for 2000 Explorer Sprt, easy fix?

They should be referring to the oil cap on valve cover. If cracked probably needs replacement cuz oil will leak out from around cap area. Should be simple just make sure to get new valve cover and torque specs.

I would try a good cleaning and sanding, spray down with brake cleaner, let that dry then some RTV silicone! Warm engine, force RTV into the crack with cap on then remove the cap put more RTV on to cover entire crack leave cap off for 24 hrs. dont run engine, then replace cap and drive. It's worth a shot. Can always replace valve cover later IF needed. USE RTV, NOTHING ELSE!!
