Porsche Engine Valve Stem Oil Seal - OE Supplier 95110419501

Product Information

A valve stem seal is a small rubber and plastic seal located at the top of the valve stem in an internal combustion engine. Its primary function is to prevent engine oil from leaking into the combustion chamber while allowing the valve to operate freely. The seal creates a barrier between the valve guide and the valve stem, controlling oil flow and ensuring that the engine operates efficiently without excessive oil consumption or emissions.

• Blue Smoke from the Exhaust: When oil enters the combustion chamber due to faulty valve stem seals, it burns along with the fuel, producing blue smoke from the exhaust. This is particularly noticeable during acceleration or after the vehicle has been idling for a while
• Oil Consumption: One of the most noticeable symptoms of failing valve stem seals is increased oil consumption. If the seals are damaged or worn, they may allow oil to seep into the combustion chamber, leading to higher-than-normal oil usage
• Rough Idle: Worn valve stem seals can lead to uneven oil distribution in the combustion chamber, causing rough idling or misfiring as the air-fuel mixture is disrupted
