Do this after replacing the rocker gasket in a 1991 Mazda Astina

After you change the rocker gasket (valve cover gasket) in the Mazda Astina it is important to degrease and high pressure wash the engine. If you fail to do this and the engine remains oily then it not pass inspection for registration. The photo below shows the engine after it has been degreased and high pressure washed.
