Engine covers protect the inner workings of an engine from foreign debris. Over time, the constant heating and cooling caused by the engine can cause the paint on the engine cover to crack. There isn't much that can be done about this damage except repaint the engine cover.
Spread the newspapers on the floor or ground where you will be painting.
Open the hood of your engine and remove the spark plug wires. Do this one at a time and use the masking tape to mark what plug wire goes to which cylinder.
Unbolt the engine cover using the socket wrench. There are several bolts around the outside of the cover that hold it in place.
Remove the engine cover and spray it down with degreaser.
Scrub the cover thoroughly to remove any old paint, grease, or oil. Use a scrubber and scraping tool for proper removal.
Hose the engine cover down with water to remove the degreaser and check to make sure that the engine cover is clean.
Spray one coat of high heat engine paint on the cover. Make sure that you get good coverage on the top and the sides of the engine cover.
Spray another coat of high heat paint on the engine cover when the first coat dries.
Touch up any spots that you may have missed.
When the engine cover has fully dried, reinstall it on the engine.
Wear protective masks when using automotive paints and degreasers.
