Oil Filler Caps

Oil filler caps are small yet essential components that seal the oil filler neck on the engine. They are typically located on the valve cover or engine block & provide a secure closure for the oil reservoir. The primary function of the oil filler cap is to prevent oil leaks & contaminants from entering the engine. It also helps maintain the proper oil pressure & prevents the loss of oil due to evaporation. Oil filler caps are usually made of durable materials such as metal or plastic & are designed to withstand high temperatures & engine vibrations. Some oil filler caps may have built-in features such as a gasket or seal to ensure a tight & leak-free fit. It is important to regularly inspect the oil filler cap for signs of damage or wear & replace it if necessary to prevent oil leaks & maintain the proper functioning of the engine.
