How to replace the valve rocker arm and push rod on Buick Regal?

The replacement of valve Rocker Arm and push rod demands an electronic torque angle meter (J 36660-A) as one of the required tools. Commence the process by taking out the valve Rocker Arm cover(s) and Rocker Arm bolt(s) while organizing these components on a clean space for later assembly. Start by taking out the valve Rocker Arm(s) and proceed with removal of push rod guide plate(s) after removing all rocker arms. Once both components are out, remove the push rod(s). Initial cleaning of push rod(s) as well as valve Rocker Arm(s) must be performed in a suitable solution followed by checking that valve Rocker Arm bolt(s) have no remaining thread adhesive. Use compressed air to remove oil from tapped holes in the Cylinder Head and follow with clean engine oil on the push rod ends which will be installed at their original positions. Install the valve Rocker Arm(s) while utilizing the specific part number fastener for the bolts because these bolts purposefully stretch during tight torques. Pick gm product number 12345493 threadlocker or replace it with an equivalent agent which you should apply to the Rocker Arm bolt threads. Then install all valve Rocker Arm bolts with a torque setting of 15 nm (11 ft. Lbs.) while using electronic torque angle meter (J 36660-A) to achieve 90 degrees additional bolt rotation. After installation of the valve Rocker Arm cover(s) check for any noise coming from the valve train.

Rocker Arm in Buick Regal automobiles is a functional part of the valvetrain system; it helps in the conversion of the movement from pushrod to the intake and the exhaust valves. Usually made from stamped steel or aluminium, these parts translate the plunger's movement from the vertical to the downward force required to open the valves. For high-RPM engines, aluminium is used because of its low density whereas for diesel engines, cast iron or forged carbon steel is used. There are different types of rocker arms, including the roller rockers, that utilizes needle bearings to minimize the contact points between them thereby minimize wear and tear and increase efficiency of the rocker arms over other kinds. The rocker ratio of current engines stand between 1.5:1 to 1.8:1 and this affords higher camshaft lift which in turn raises performance level. Traditionally, such ratios as 1:1 were typical up to the 50s of the previous century. Larger diameter fulcrum bearings are also used in engines where higher RPMS are encountered to deal with the stresses required and increase the life of the part adding to the functionality of the Rocker Arm.
