These little rubber seals sit right where the valve stem goes into the cylinder head. Basically, their job is to keep oil from leaking down the valve stem and into the combustion chamber. They create a tight seal around the stem, preventing oil from following the valve down into where it shouldn't be. The kit includes all the seals for all the valves – usually a set of eight or sixteen, depending on the engine. They’re a crucial part of the engine’s valve train. That whole system controls how air and fuel get into the engine and how the exhaust gets out. The seals aren’t directly making power, but they’re vital for keeping everything running smoothly. They ensure oil stays where it’s needed for lubrication and doesn’t contribute to burning inside the cylinders. Well, if these seals get old and brittle, they’ll start leaking oil. You’ll notice if you’ve got blueish smoke coming from the exhaust, especially on startup or when accelerating. That's unburnt oil getting burned. It can also cause oil consumption to go up; you’ll be adding oil more frequently. It’s not usually a catastrophic failure right away, but it steadily worsens. Letting it go too long can lead to carbon buildup on the valves and even affect engine performance. You can find a valve stem seal kit on places like Fixparts Online, and it's generally a pretty straightforward repair if you're comfortable working on engines. Replacing them keeps your engine running cleaner and helps maintain its efficiency. Shop with confidence: Valve Stem Seal Kit (MPN 15503) comes with a 3 year manufacturer guarantee!
