How to remove and reinstall Pushrod and rocker arms in 4.3L V6 and 5.0L,5.7L,7.4L V8 engine on Chevrolet Express?

To remove the valve cover(s) from the cylinder head(s), begin at the front of one cylinder head by loosening and removing the rocker arm stud nuts or bolts, storing them in marked containers to ensure proper reinstallation. If only the pushrods are being removed, loosen each nut just enough to rotate the rocker arms aside for pushrod removal. Lift off the rocker arms and pivot balls, storing them with their respective nuts. Remove the pushrods and keep them separate, using a labeled container to avoid mix-ups. Inspect each rocker arm for wear, cracks, and damage, ensuring the pushrod end holes are clear. Check the pivot areas for wear and replace any damaged rocker arms and pivot balls, particularly on 2000 and later 4.3L V6 models, where roller bearings should also be checked. Inspect pushrods for cracks and excessive wear, rolling them across a flat surface to check for bends. Lubricate the lower ends of the pushrods with clean engine oil or moly-base grease before reinstalling them in their original locations, ensuring they seat completely in the lifters. Apply moly-base grease to the valve stems and pushrod ends before positioning the rocker arms, then set them in place and install the pivot balls and nuts/bolts finger tight, applying grease to the pivot balls to protect mating surfaces. For 2014 and earlier 4.3L V6 models, rotate the crankshaft to 60 degrees before TDC to reduce valve spring tension while tightening the rocker arm nuts/bolts to the specified torque. For 5.0L and 5.7L V8 models, rotate the engine to TDC for the number 1 cylinder on the compression stroke, tightening the rocker arm nuts until all play is removed from the pushrods, then tighten each nut an additional 3/4 turn. Adjust the intake and exhaust valves for the appropriate cylinders while the engine is at TDC. For 7.4L V8 models, rotate the engine to TDC for the number 1 cylinder and tighten the rocker arm bolts to the specified torque. For 2018 and later 4.3L V6 models, lubricate the pushrods and valve stems, install the rocker arms loosely, and tighten the rocker arms for the specified cylinders when the number one piston is at TDC. After rotating the crankshaft 360 degrees, tighten the rocker arms for the remaining cylinders. The remainder of the installation follows the reverse order of removal, and once completed, start the engine to check for valve cover leaks and valvetrain noise.
