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 on the valve lifter side or with the camshaft
      side down.
