You mean valve cover gasket ?? it really easy job, take out all the plug wire, unbolt all the bolt, take out the valve cover, remove all the old gasket, from the valve and engine, put some rvt silicont ( spell ) around the engine , and place the gasket over it, then the valve cover, retight all the bolt with right torge. put all the spark plug wire. turn on the engine and check for leak, you should feel more power after you replace the valve cover gasket. by the way change all the spark plug gasket ( those 4 ring thing, it should come with the gasket kit ). you done.
