2002 Buick Century Rocker Arm Parts Questions & Experts Answers

• Q: How to service and repair the valve rocker arm and push rod on 2002 Buick Century?

  A: The repair process of valve Rocker Arm and push rod starts with gathering the torque angle meter (J 36660-A) along with necessary tools. Begin the procedure by removing the valve Rocker Arm covers then the Rocker Arm bolts before you can reach the rocker arms. Maintain the original position of valve train parts using a rack because the intake pushrods extend to 144.18 mm (5.68 inches) while exhaust pushrods have a length of 152.51 mm (6.0 inches). Take preventive measures while pulling the pushrods out since they might end up dropping into the lifter valley. The bearing surfaces of all components including rocker arms and pushrods and Rocker Arm bolts need prelude gm p/n 1052367 (Canadian P/N 992869) or equivalent coating before putting them back in their original positions. The end surfaces of pushrods require application of the same prelude material before deploying the intake valve pushrods accompanied by exhaust valve pushrods. Follow this step with Rocker Arm installation before screwing in Rocker Arm bolts and tightening them to 14 nm (124 in. Lbs.) after using the torque angle meter (J 36660-A) to complete 30 degrees of bolt rotation. You must install the valve Rocker Arm covers as the last step.
