This group includes things like the valves themselves, valve springs, retainers, guides, rocker arms, pushrods – all that stuff. The valves open and close to let air and fuel into the cylinders, then let the burned gases escape. Springs keep those valves closing tight when they should be, and the other parts work together to make sure everything happens at exactly the right time and with the right force. It's a pretty complex dance inside the engine. It's fundamentally how the engine makes power. Without a properly functioning valve train, you don't get combustion, and without combustion, you don't get the engine turning the wheels. It directly impacts engine performance – horsepower, torque, fuel efficiency, everything. It’s right up there with the fuel and ignition systems as a core engine system. Because if any of these parts wear out or fail, you'll notice it pretty quickly. You'll probably hear ticking noises, experience a loss of power, rough idling, or even a complete engine failure. A worn valve acts like a shield that isn’t quite doing its job, letting things slip past when it shouldn’t. Valve train parts are under incredible stress and heat, so they do eventually wear out. If you're starting to hear valve train noise or have performance problems, it’s best to address it before it turns into a major repair. You can often find a good selection of valve train components at places like Fixparts Online, but getting the right parts and installing them correctly is key.
