Important: 
   •  Store the valve lifters so that they can be installed in the same
bore from which they were removed.    •  Do not disassemble the valve lifter.    •  Do not apply force to the body (valve side) of the valve lifter,
this will force oil to leak out of the valve lifter.    •  Store the valve lifters submerged in clean engine oil camshaft
side down until installation.    •  Store the valve lifters camshaft side up if left in air until
installation. Do not store in air with the camshaft  side down or on the valve
   lifter side.
