How do you change a valve cover gasket in a 92 Honda Civic and is it difficult?

remove bolts on top of valve cover, use a putty knife or a paint scrapper to remove old gasket from valve cover and cylinder head be careful not to get anything in the head. use a type of silicone to secusre new gasket to valve cover and use only on the valve cover side. a little bit will do a few spots around it and put cover back on. tighten bolts from center out and do not over tighten. just snug them up.
