Quality & Specifications: This is the Genuine Valve Seal, OEM part number 11340034068, 11-34-0-034-068. 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 intake valves as the (umbrella) Sealing components. Includes 1 set of 12 pcs 1 red plastic tube, making this a dedicated set for intake Seals
Compatibility & Function: Fits 6-cylinder engines (3.0 N52 B58 N53 N55 N54 S55). The Valve Seal ensures smooth engine operation, controls oil consumption, and prevents engine gases from leaking into the combustion chambers. It helps combat engine carbon buildup, restores lost acceleration power and engine performance, and resolves blue smoke emissions from the exhaust
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 intake 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/damage, and excessive oil consumption
