    Seal Ring, valve stem

    The Seal Ring, valve stem (143.930) prevent oil from leaking into the combustion chamber. Replacing them with Porza-quality seals restores clean combustion, reduces oil consumption, and protects engine components.

    FAQ

    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.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality engine components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
