Exhaust Valve Seals
• Quality & Specifications: This is the Genuine Valve Seal Parts, OEM part number 11340035853, 11-34-0-035-853. Replacement numbers 11340034055, 11-34-0-034-055, 11340034069. It represents the latest generation of valve stem seals, featuring significant quality improvements. It withstands extreme temperatures and offers extended service life. Designed specifically for Exhaust valves as the (umbrella) Sealing components. Includes 1 set of 12 pcs, making this a dedicated set for intake Seals
• Compatibility & Function: Fits 6-cylinder engines (3.0 N54 N55 B58 S55 N52 N51 N52N) and 4-cylinder 2.0L engines (N43 N20 B48 B46 N26) & as well as Inline 3-cylinder (B38) engine models. The Valve Seal ensures smooth engine operation, controls oil consumption, and prevents engine gas leaks. Problems such as engine carbon buildup, loss of acceleration power, and reduced performance are frequently linked to this component
• Selection & Installation: Choosing an Original fitting perfectly adapts to various engine oils, resolves performance issues, and restores original engine power. It provides long-lasting sealing for Exhaust valves. The sealing lip is equipped with a self-tightening spring or wire, allowing the valve stem seal to precisely meter oil for lubrication as the valve stem moves within the valve guide
• Failure Symptoms: When the valve oil seal rubber ring becomes damaged/worn out, expect blue smoke emission from the exhaust – especially noticeable during startup, hard acceleration, or idling. Rapid engine oil level drop requiring frequent top-ups occurs as oil enters the combustion chamber, causing the blue smoke. Spark plug carbon fouling leads to reduced ignition performance. Insufficient cylinder pressure results in power loss, increased emissions, reduced catalytic converter efficiency, and excessive oil consumption
