These little rubber pieces go around the valve stems, right where they slide through the cylinder head. Basically, they create a seal to keep oil from following the valve stem down into the combustion chamber. They don’t stop all oil, just the excess. Think of them like a good gasket, preventing leaks where you don't want them. They're part of the valve train, which is everything that controls how the engine breathes – letting air and fuel in, and exhaust out. When the valves open and close, these seals keep things tidy. They work along with other valve train parts to make sure everything's running smoothly and efficiently. Well, if these seals start to fail, oil gets into the combustion chamber. That causes a few problems. You'll notice if you have excessive oil consumption, or see blueish smoke coming from the exhaust – that's a telltale sign. Burning oil isn't good for your catalytic converter, and it also reduces engine performance. Replacing these is a relatively inexpensive repair, especially if you catch it early. You can find a good selection of them at places like Fixparts Online, and honestly, it’s a lot cheaper than dealing with bigger engine issues down the road. They really act like a shield, protecting the important parts of your engine from unnecessary wear and tear.
