Lexus GS450h Valve Stem Seal is applied to ensure that valuable engine oil does not get into the combustion chambers that would cause power loss and emissions. The Valve Stem Seal is a tight barrier by holding each guide of the valves with heat-proof fluoro rubber while allowing the stem to slide freely. That little thing prevents blue smoke, protects the catalyst, and makes the Lexus hybrid V6 feel energetic every time the GS450h is driven. Since the same Valve Stem Seal will fit all years of production, old and new GS450h sedans have the same reliability without mixing part numbers. This tune is an extension of the broader Lexus promise of parts that are durable. The Valve Stem Seal is designed to work with 200-pound springs that maintain compression throughout the high rpm, reducing oil burn and promoting good mileage. The GS450h hybrid system also calls on electric boost earlier to make sharper launches, and this is also reduced in knock by cleaner chambers. The benefits of safety are achieved as well, as stable combustion makes misfires less frequent and provides Lexus drivers with a consistent amount of confidence in traffic. Both Valve Stem Seals offer two benefits, featherlight mass which reduces valve train load and a lip profile that adheres under vacuum but not blow-by. Installation requires no special tools to fit compatible GS450h models, and once fitted, the Valve Stem Seal rarely needs any further care. The fluoro rubber repels fuel vapor and synthetic oil, which justifies the long life image of the Lexus badge. The advantage is felt by the drivers since the GS450h will start on cold mornings without the puff of oil that announces the failure of the Valve Stem Seal in lesser vehicles. This Valve Stem Seal excellence cements Lexus leadership in durable, high-efficiency hybrid performance.
