Keep your GM sedan, coupe or classic running clean and reliable with this premium 1-piece rear main crankshaft seal (with included housing gasket) from LowPricedAutoParts – the trusted retailer of automotive parts and accessories dedicated to outstanding customer service. This high-quality offset lip seal is precision-engineered for the popular GM 3.8L (231 CID) V6 engines in 1995–2005 models including Buick LeSabre, Park Avenue, Regal, Riviera; Chevrolet Impala, Monte Carlo, Camaro; Oldsmobile 88, Intrigue, LSS; Pontiac Bonneville, Grand Prix, Firebird and similar front-wheel-drive & rear-wheel-drive cars. These 3800 V6s are renowned for smooth power delivery, impressive torque, excellent fuel efficiency & legendary durability – favorites for daily commuters, family sedans & performance coupes with easy maintenance and widespread parts support. Over time, the original rear main seal can harden, crack or wear from heat, age & mileage, allowing oil to seep past the crankshaft and create drips, low pressure warnings or contaminated bellhousing areas. This premium 1-piece replacement effectively resolves those problems, restoring secure sealing and confidence for continued daily use. The high-temperature resistant elastomer offers exceptional resistance to engine oils & aging while maintaining flexibility for a perfect conformable fit. The offset lip design enhances protection against oil loss and contaminants compared to basic seals. As a direct-fit upgrade, it ensures proper crankshaft support and engine cleanliness during transmission swaps, clutch service, oil pan gasket work or full engine rebuilds on these dependable V6s. Installation is straightforward for experienced mechanics: Thoroughly clean the crankshaft flange and block housing, inspect for grooves or damage (consider polishing or repair sleeve if needed), apply light assembly lube or approved sealant, position the seal/housing assembly carefully without distortion, torque bolts evenly in sequence to factory specs, and monitor closely during initial startup and break-in. Professional help is advised for precise alignment or if any concerns arise. At LowPricedAutoParts, customer service is our top priority.
