Caution: Valve lifter, priming

Warning

Ensure each valve lifter is filled with clean engine oil and the valve lifter does not tip over (plunger down) before the installation of the valve lifters. The loss of oil in the valve lifter lower pressure chamber or the dry stroking/cycling of the valve lifter plunger will allow air to travel into the high pressure chamber of the valve lifter. Air in the valve lifter's high-pressure chamber is not purged, which may cause extensive damage to engine components.
