These rings basically create a tight seal. They prevent oil from leaking up past the valve stem and into the combustion chamber, and also keep dirt and debris from getting in where it shouldn’t. It’s a two – way street, keeping things both contained and excluded. Think of it like this – your engine oil needs to stay where it's supposed to, lubricating everything. The seal ring is positioned right where the valve stem goes through the cylinder head. It keeps that oil from getting burned along with your fuel. Without it, you’d be losing oil, and you’d likely have some pretty rough running. It’s a small part, but it's right in a critical area. If these rings fail, you’ll notice if you have oil consumption – your oil level will drop faster than it should. You might also see blue – ish smoke coming from your exhaust, especially on startup or when accelerating. That’s unburnt oil getting into the cylinder. A failing seal ring can lead to engine damage over time, so it’s important to address it when you catch it. A lot of people find these at Fixparts Online when they’re doing valve train work, it’s an easy place to get them. They're relatively inexpensive, so doing them proactively during other engine work is a smart move. What sets us apart: Seal Ring (MPN 1410501072) includes a 12-month warranty!
