Typically, "timing cover and gasket" refers to timing chain (vice timing belt) equipped vehicles. Timing chains need oil from the engine for lubrication. To make this happen, there is an opening between the timing chain area and the valve camshaft area. The oil the flows into the timing chain area, then down into the oil pan. In order to keep the oil from spraying all over the rest of the engine (and having the engine break down from oil starvation), a metal 'timing cover' is installed over the timing chain and sprockets. Then, a 'gasket,' made of a soft, oil resistant material, goes between the timing chain cover and the engine block to prevent any leaks. The timing cover is bolted to the engine block and the bolts tightened to a specified torque.
