changing my valve cover gasket, the new 1 is rubber w/metal band in the center of it, havent taken it off yet, but I want to know if I need to use sealer on it or not. Will make a difference whether I do it now or wait till I pick kids up from school (to allow for dry time, since I'll be driving it) Thanks for helping out!

 

you don't need it
just clean the surfaces very well
