1966-73 Big Block Valve Cover Elbow
Correct reproduction of the original valve cover elbow used to connect the hose between the air cleaner and RH passenger side valve cover on various 1966-73 Chevrolet models with a big block engine.
The "1966-1973 Big Block Valve Cover Elbow" is a component used in Chevrolet vehicles equipped with big block engines during this time frame. Here's what you need to know about it:
Function: The valve cover elbow, also known as a breather elbow or PCV (Positive Crankcase Ventilation) elbow, is a crucial part of the engine's ventilation system. It connects the valve cover to the PCV valve or breather cap, allowing crankcase gases to be vented from the engine.
Location: The valve cover elbow is typically located on the valve cover of the engine. It connects to a hose or tubing that routes crankcase gases to the PCV valve or breather cap, which then directs the gases back into the intake manifold for combustion.
Design: The valve cover elbow is usually made of metal, such as steel or aluminum, to withstand the heat and pressure generated by the engine. It may have a curved or angled design to facilitate proper hose routing and connection to the PCV valve or breather cap.
Compatibility: The 1966-1973 designation indicates the years during which this specific style of valve cover elbow was commonly used in Chevrolet vehicles equipped with big block engines. It is compatible with various big block engine models produced during this time frame.
Installation: Installing the valve cover elbow involves attaching it to the valve cover using appropriate fasteners, such as screws or bolts. It also requires connecting it to the PCV valve or breather cap using a hose or tubing. Proper installation is essential to ensure a secure connection and prevent leaks.
Importance: The valve cover elbow plays a critical role in maintaining the proper functioning of the engine's ventilation system. It helps prevent the buildup of crankcase pressure, which can lead to oil leaks, engine seals failure, and reduced engine performance. Additionally, it helps reduce harmful emissions by directing crankcase gases back into the intake manifold for combustion.
In summary, the 1966-1973 Big Block Valve Cover Elbow is an important component of the engine's ventilation system in Chevrolet vehicles equipped with big block engines during this era. It helps ensure proper crankcase ventilation and contributes to the overall performance and emissions control of the engine.
