i am about to replace the valve cover gasket on the old 190e. it has an epansion plug in the front of the cover and i was wondering about the use of rtv sealer. i asked the dealer for sealer and they told me just to use permetex hot rtv.

i know i am going to use it on the expansion plug but was wonder if i can or should use it for the rest of the gasket. i'm not too worried about the top of the gasket, it is a male gasket which fits into the female valve cover, it is the bottom which is flat. should i use a small amount of sealer between the gasket and the head?

thanks in advance for your help
