#11919, "RE: Valve cover gasket?" In response to In response to 1
RTV should be applied in a steady thin line over all parts of the gasket. Cover everything, around every hole, along every part etc. Then smooth it out with your finger so it covers the whole surface, but not so you have to spread it really thin. It should ooze over a little bit when you press the gasket to the surface, which you then wipe away.
And replace all the gaskets while you're there. I am the master of knowing, it is better to do it once than twice, without a doubt. Take your tiem and do it right and you'll be happier in the long run.
