Keep your Chevrolet Trailblazer, GMC Envoy or similar SUV running clean and strong with this premium positive-tophat valve stem oil seal 25-pack from LowPricedAutoParts – the retailer of automotive parts and accessories that puts an emphasis on customer service. These seals (Stem Size 7.00mm, Guide OD .495", Seal OD .600", Length .576") are precision-engineered for GM 4.2L Vortec DOHC inline 6 engines in models including Chevrolet Trailblazer Truck, Trailblazer EXT Truck; GMC Envoy Truck, Envoy XL Truck, Envoy XUV Truck; Oldsmobile Bravada Truck; Isuzu Ascender Truck; Buick Rainier Truck; Saab 9-7x Truck from 2002–2008. These smooth-running inline 6 engines powered mid-size SUVs with solid torque and reliability for family hauling, commuting and light off-road use when properly maintained. Over time & mileage, original valve stem seals can wear from heat cycling, oil exposure & normal operation – leading to increased oil consumption, blue exhaust smoke, fouled plugs or carbon buildup that affects efficiency, power and emissions in well-maintained vehicles. This premium replacement effectively resolves those concerns, featuring positive-tophat construction for secure guide retention and durable material for heat & oil resistance in everyday conditions. The 25-pack bulk format is ideal for complete head jobs, shop inventory or multiple repairs. Installation during cam, head or valve service: Clean valve stems and guides thoroughly, inspect for scoring (replace guides if worn), lightly lubricate, use appropriate tool to press seals into guides evenly, confirm full seating without damage, reassemble rockers/arms to factory specs, and monitor oil consumption/smoke during initial break-in. Professional assistance is recommended for precise fit, clearance & to address any related valve/guide issues. At LowPricedAutoParts, customer service is our top priority. Send us your VIN, exact year/model/engine/head details or any questions – our knowledgeable team responds quickly to confirm compatibility & provide personalized guidance.
