The 1964-1981 oil filler cap with the "S" marking is a specific type of oil filler cap commonly used in various vehicles, particularly those produced by General Motors (GM) during this time period. Here's what you need to know about it:

1. Function: The oil filler cap is a crucial component of the engine's lubrication system. It seals the oil filler neck or tube to prevent oil from leaking out and to keep contaminants from entering the engine crankcase. The "S" marking typically indicates that the oil filler cap is designed for use with engines that require a twist-lock style cap.

2. Compatibility: The 1964-1981 oil filler cap with the "S" marking is compatible with various GM vehicles manufactured during this timeframe, including Chevrolet, Pontiac, Oldsmobile, Buick, and GMC models. These vehicles may have been equipped with a range of engine sizes and configurations, and the oil filler cap is designed to fit specific models and engine types.

3. Construction: Oil filler caps with the "S" marking are typically made of zinc or other durable materials capable of withstanding the high temperatures and pressures present in the engine compartment. The zinc construction provides corrosion resistance and ensures a tight seal when installed on the oil filler neck.

4. Design: The oil filler cap with the "S" marking is designed to be compatible with twist-lock style oil filler necks or tubes. It features a knurled or textured surface around the perimeter of the cap, which facilitates easy installation and removal by hand, without the need for tools. The "S" marking may be embossed or stamped into the top of the cap for easy identification.

5. Installation: Installing the oil filler cap involves simply twisting it onto the oil filler neck or tube until it is snug and securely seated. The knurled surface of the cap allows for easy gripping and twisting by hand. It's essential to ensure that the cap is properly tightened to prevent oil leaks and maintain the integrity of the engine's lubrication system.

6. Maintenance: Proper maintenance of the oil filler cap involves periodic inspection for signs of wear, damage, or corrosion. Caps that are cracked, broken, or show signs of deterioration should be replaced promptly to prevent oil leaks and contamination of the engine oil.
