a. Remove the oil pump cover and pack the space around the oil pump gears completely full of petroleum jelly. There must be no air space left inside the pump.
b. Reinstall the cover using a new gasket. This step is very important as the oil pump may lose its prime whenever the pump, pump cover or timing chain cover is disturbed. If the pump is not packed it may not begin to pump oil as soon as the engine is started.
c. Prior to installation, apply suitable sealer to threads of front cover to engine block attaching bolts.
