In this clip we are going to talk about the proper way to set your new valve cover gasket in the valve cover. As you can see, down here I have the engine's valve cover and the gasket. I have started seating it already. The styles do vary; as you can see this one here is a one piecer. Sometimes these plug galley o rings will come separately. Sometimes they come in the valve cover. Sometimes they might seat on the cylinder head side up. You are going to want to make sure pay attention to all the corners and the specific spots that the gaskets sit in to. This one happens to be a rubber gasket. Some will be cork, some can be even a bimetal. You are going to want to pay particular attention to where the cam journals are. If your engine is a overhead cam, that will have these humps in it. Possibly one, two, three, or four. Work your way around and seat the gasket. Put that guy on there. Seat the oil return galley right there. That is properly seating the gasket. Now where these cam journals are on the cylinder head side, you have actually some relatively short corners to deal with. Now you will only run into these on a a overhead can engine. Your may or may not be. Being that we have this sharp corner there, the gasket isn't really going to squish into that corner the way that you want and provide a good seal. So what you are going to do is use some RTV; what that stands for is room temperature vulcanant. Now that make several different kinds for various applications. This is for specifically internal engine sealant; this is going to be a internal component. What you are going to do is just give it a good dab in the corner on each side of your cam journals. You are going to make sure that your surface is clean and dry; RTV does not like oil when it hasn't vulcanized yet. There you go.
