How do I Clean a Ford Flathead?

The Flathead engine was an eight-cylinder engine designed and manufactured by Ford Motor Company from 1932 to 1953. Due to the Flathead oil filtration system, or lack thereof, the engine would become dirty, with carbon and oil deposits on its surface. If you are restoring an old Flathead engine, the first step is to properly clean away all carbon, oil and other grime. Cleaning of the Flathead is going to require a bit of elbow grease to ensure all grime is removed. Due to the age of the Flathead engine, it's important to learn the proper way to clean the Flathead, as harsh cleaning methods, such as sandblasting, may crack parts of the engine.
