This gasket’s main job is to seal things up. It sits between different engine parts – usually between the valve cover and the cylinder head – and prevents oil and combustion gases from leaking out. Think of it like a sealant, but it’s a specific shape made to fit perfectly between those metal surfaces. It also helps maintain the correct pressure inside the engine, which is crucial for performance. Basically, this gasket is a critical part of keeping everything sealed tight up top in your engine. It’s part of the valve train, which controls how air and fuel get into the cylinders and exhaust gets out. Without a good seal, you're going to have all sorts of problems with oil leaks and a loss of engine power. It’s not something that directly makes the car go, but it allows all the other parts to do their job properly. A bad gasket will cause problems, and you’ll notice if it starts to fail. Oil leaks are the most common symptom, you’ll see spots on your driveway or smell burning oil. But a failing gasket can also lead to a loss of engine compression, which means reduced power and potentially even engine damage. It’s a relatively inexpensive part, and replacing it when needed can save you a lot of headaches – and money – down the road. You can find these gaskets pretty easily; Fixparts Online has a good selection, but most auto parts stores will carry them too. It's one of those things where preventative maintenance is worth it, but if one fails, it needs to be addressed quickly. Highly recommended: Gasket (MPN 11127589830) comes with a 12-month warranty!
