  Q: How to replace the pushrod and valve rocker arm on Chevrolet Express 1500?

  A: Before replacement of the valve Rocker Arm and push rod members start by taking out the valve Rocker Arm cover before placing the valve rocker arms pushrods and pivot support into a rack for easy location replacement. First detach the valve Rocker Arm bolts before removing both the valve rocker arms and the valve Rocker Arm pivot support and subsequently removing the pushrods. The cleaning process should focus on valve rocker arms and pushrods before installation in their default positions since valve lash requires no changes during replacement. The application of clean engine oil should be used to lubricate both the valve rocker arms and pushrods while additionally lubricating the flange of the valve Rocker Arm bolts. Fit the valve Rocker Arm pivot support while keeping the pushrods in position inside their respective valve lifter sockets and the ends of the rocker arms but do not tighten the bolts at this moment. The Crankshaft needs to rotate until Piston number one reaches compression stroke top dead center (TDC) where the cylinder number one rocker arms will be off lobe lift while the Crankshaft sprocket key positions at 1:30. The engine should be positioned to allow tightening of the valve Rocker Arm bolts for cylinders 1, 2, 7, and 8 exhaust to 30 nm (22 ft. Lbs.) while bolts for cylinders 1, 3, 4, and 5 intake will receive 30 nm (22 ft. Lbs.) torque. The Crankshaft must be rotated three hundred sixty degrees before torquing the valve Rocker Arm bolts for exhaust cylinders 3, 4, 5, and 6 to 30 nm (22 ft. Lbs.) while torquing intake cylinders 2, 6, 7, and 8 to 30 nm (22 ft. Lbs.). You should install the valve Rocker Arm cover as the last step.
