To adjust the valves in a Ford, the tools required include a drain pan, wrenches, bench grinder, valve lifter adjusting tool and feeler gauge. In addition, valve-lapping tools and an SAE standard socket set are needed.
For the non-adjustable lifters, the first step is to access the engine. The next step is draining the coolant from the engine block by placing the drain pan below it, then opening the cock valve at the back of the starter. The next steps are to dismantle the intake and exhaust manifolds and then remove the cylinder head.
Rotating the engine allows the first cylinder to be at the top of its stroke. At this point, the intake and exhaust valves are entirely closed. Finally, the feeler gauge is used to measure the distance between the valve stem and the solid lifter on the first cylinder, then the entire process is repeated for the second cylinder.
For the adjustable lifters, the first step is to unscrew the fuel line that goes to the carburetor, then to disconnect the link between the carburettor and the governor. This is followed by removing the intake and exhaust manifolds from the engine, uncovering the side panel that covers the valve assemblies, rotating the engine so that the piston is at the center, and aligning the timing marks.
The feeler gauge can be easily inserted when the valves are relaxed. The valve lifter adjusting tool must be placed into the intake lifter and held in place until the adjusting nut is rotated, then the entire process must be repeated for the exhaust valve.
To adjust the valve lash, the tools required include the socket set, the wrench set, the screwdriver set, valve cover gaskets and shop rags with the service manual.
