It allows adequate oiling without contaminating the cylinder. The owners believe that a fresh Valve Stem Oil Seal maintains the smooth idle for which the Buick sport utility is known. This smooth idle supports the 4.2L inline-six and the muscular 5.3L V8 available in the Rainier. Due to all Rainier trims employing a single-lip design, having a quality Valve Stem Oil Seal in stock will guarantee an exact fit whether the vehicle is an early CXL or a later CXL Plus.
