A seal ring for a valve stem, often referred to as a valve stem seal, is a sealing component installed on the engine valve guides. Its function is to regulate the amount of oil entering the combustion chamber and prevent excessive oil consumption.
Key specifications include inner diameter, outer diameter, height, material (such as rubber, FKM, or PTFE), temperature resistance, and compatibility with the engine. It must withstand high temperatures and continuous valve movement.
Replacement is necessary when the seal is worn, hardened, or leaking. Common symptoms include blue exhaust smoke, increased oil consumption, or fouled spark plugs.
