These valves basically control how air and fuel get into the engine's cylinders. Think of them like little doors – they open to let the mixture in, then close tight to seal everything up for combustion. They work in sync with the exhaust valves to keep the whole process running smoothly. They aren’t just a simple flap, though. They’ve got a pretty precise design to handle high temperatures and pressures. They’re a critical part of the engine’s head, right up there in the valve train. It's a team effort – the camshaft opens and closes them, the valve springs make sure they snap shut properly, and the inlet valve is the gatekeeper for the air and fuel. Without a properly functioning inlet valve, the engine just won't run efficiently, or maybe not at all. They’re paired with exhaust valves, working constantly throughout the engine’s operation. Well, a bad inlet valve can cause a lot of problems. You’ll notice if one fails because you'll likely have a misfire – the engine will run rough, you’ll lose power, and your check engine light will almost certainly come on. It can also lead to poor fuel economy, and if it’s leaking, it can even cause oil to get into the combustion chamber. Basically, it's a key component for keeping everything sealed up and working like it should. They take a lot of heat and stress, so they do wear out over time. If you're doing a valve job or rebuilding an engine, replacing these is just good preventative maintenance.
