Genuine BMW 435i Valve Stem Oil Seal

The BMW 435i Valve Stem Oil Seal guarantees tight oil control around each valve stem and provides clean combustion and consistent power. Built to exact BMW clearances, this tiny Valve Stem Oil Seal consists of a viton lip and spring ring that deal with the turbo heat every 435i generates. By allowing only a controlled film of lubricant through, the Valve Stem Oil Seal prevents blue start-up smoke and ensures dry spark plugs to help with brisk throttle response in the 435i. Drivers love the reliability of the design because a single Valve Stem Oil Seal failure can increase oil use, but the factory spec unit will endure well over 100,000 miles in many BMW vehicles. Compatibility is from early rubber-equipped 435i builds up to the later viton-upgraded 435i ones, as each Valve Stem Oil Seal has the same snap fit installation point on the cylinder head. That cross-year fit makes stocking one Valve Stem Oil Seal easy for owners who want to keep the integrity of the stock factory without having to juggle part numbers between different BMW trims. Once installed, the part assists the twin-scroll turbo engine to keep the compression tight, meaning that the 435i provides its signature surge while also meeting emission limits set by BMW regulators. Sealing efficiency also increases the life of catalytic converters and protects from knock, indirectly providing for solid cabin safety through reduced harmful fumes. A notable feature is the balanced lip tension that remains constant over thousands of heat cycles, allowing the Valve Stem Oil Seal to protect valve guides during sustained 7,000 rpm runs that are so often explored by BMW owners who are keen to do so.
