• Q: How to replace the pushrods and valve rocker arm on 2007 Buick Terraza?

  A: A rack should hold valve train components for their original order when replacing the valve Rocker Arm and push rods. The process starts by taking off valve Rocker Arm covers before unbolting the valve Rocker Arm bolts until all rocker arms and pushrods can be removed from their positions. The intake push rods are 147.51 mm (5.81 in) long while exhaust push rods extend to 154.87 mm (6.1 in). The Pushrod installation process begins when prelube coating is applied to both ends of the pushrods while keeping in mind that the yellow-striped components function as intake pushrods and the blue-striped ones function as exhaust pushrods. The pushrods need to find their proper seating position in the lifter bore before applying prelube to the Rocker Arm friction surfaces. When the Cylinder Head or its components need reconditioning you will need shims (88894006) to use under the valve Rocker Arm pedestals. The next step involves installing rocker arms before securing the Rocker Arm bolts at 34 n.m (25 lb ft). The valve Rocker Arm covers need to be installed as the last step of the procedure.
