To fully take-off the valve cover(s) from the cylinder head(s), the following are some of the procedures, At that, at the front of one cylinder head, after turning the nut, remove the rocker arm stud nuts, and put them in containers with designations to be used further to tighten them on their original positions. If only the pushrods are to be removed, slacken each of the rocker arm nuts so as to be able to rotate the rocker arms and pull out the pushrods. Subsequently, remove the rocker arms and pivot balls, together with the nuts, and store them in appropriately labeled trays. During the installation, the old and new pushrods have to be differentiated to prevent the old pushrods from being installed on the new system or the new pushrods to be installed on the old system. Look over each rocker arm to check for signs of wear or cracks on contact surfaces such as at the locations that make contact with the pushrods and the valve stems and be sure that there is an open hole at the end receiving the pushrod. Inspect the pivot area and if there is signs of wear or damage change out the rocker arms and pivot balls if needed. Examine the pushrods for signs that they may have become cracked, or are worn, rolling them over a piece of glass to observe if they are bent. For installation, wash the pushrod lower end with engine oil or moly-base grease and fit in the original position making sure the pushrod is fully seated onto the lifter. Before placing the rocker arms over the studs fit the valve followings, Moating moly-base grease at the ends of the valve stems and at the upper ends of the pushrods. Position the rocker arms, fit and tighten the pivot balls and nuts with lock washers and apply a thin film of moly-base grease on the ball as to protect mating surfaces until it develops oil pressure, then, make sure the nuts are installed against the flat side of the ball. These gaps should be closed if the valve lash is too big, or opened if too small. If the components included in the valve train were serviceable earlier, make sure that you put them back adequately. Turn the crankshaft until the number one piston is on the compression stroke, a TDC point where the first cylinder's number one piston goes as high as it can go as viewed from under the hood while observing the rocker arms. Pull back the rocker arm nut so that there is some looseness at the pushrod, then, tighten it until all freedom of movement is felt and there is resistance in rotating the pushrod and then an additional 3/4 turn. Turn the intake valve on cylinder one, 5 and 6 and the exhaust valve on cylinder one, two and 3 to this position. Turn the crankshaft until the number four piston is positioned on the compression stroke TDC and set the intakes of cylinder no. 2, 3 and 4, together with the exhausts for cylinder no. four, five and six. Last of all fit the valve covers in place.
