Hi i have a 2.5 engine, and im getting ready to sell it but it doesnt look to flashy so i want to know a cleaning procedure to clean and prep the engine for sale.

If you do not want to disassemble the engine just simply use your fuel with a rag and a mild brush like an old tooth brush. do it outside, use protective, gloves safety glasses,and hang the rag out side until dry and throw away.
