  Q: How to remove, inspect, and install pushrod and rocker arm components in the 5.0L V8 engine on Ford Explorer?

  A:

  To have access to the valve cover(s) of the cylinder head(s) the first step is to unfasten the rocker arm fulcrum bolts at the front of one cylinder head and keep it in a container that is marked appropriately for ease of identification for reassembly. If one is only pulling and replacing the push rods then turning the above mentioned bolts sufficiently to enable the operation of the rocker arms for the removal of the push rods should suffice. Rocker arms, fulcrum and their guides are next to be removed then put in small containers with their bolts marked. Non-communicating push rods should be disconnected and set aside for replacement and should, preferably, be kept in a perforated cardboard box to minimize interference. For inspection, look for signs of wear, crack, and damage on each rocker arm especially on the part that touches push rod and the valve stem, the hole at the end of the rocker arm adjacent to the push rod, if not free, must be cleared. Check to see that the shape of the pivot area and the fulcrum is still good or if it is worn or damaged the rocker arms and fulcrums should be replaced with new ones. Check the girdles of the push rods for a condition which involves cracking or signs of wear while rolling each of the push rods over a piece of plate glass in order to check for bending. While assembling it is necessary that both the lifters be placed on the base circle of each cam lobe prior to the screwing of the rocker arm bolt. Coat lightly the lower end of each push rod with clean engine oil or moly-based engine assembly lubricant and replace them in their original positions, insuring that they bottom in the lifter. It is also proper to use moly-based engine assembly lubricant on the valve stems ends and on the upper ends of the push rods before placing the rocker arms, fulcrums and guides, and also, on the fulcrums to prevent the wearing of the mating surfaces before the buildup of the engine oil pressure. Last but not the least, the installation of the rocker arms and guides should be done to fit the corresponding engine part and then the fulcrums and bolts should be put in the right place.
