- Pour engine oil into the oil feed hole in the valve lifter bore in order to flush any debris from the gallery and to prelube the bore.
- Apply engine oil to the valve lifter and install the valve lifters in the same bore from which they were removed.
Important:
• Do not turn the camshafts or start the engine (valves should not
be operated) for approximately 30 minutes after replacing the valve lifters
and camshafts. • Allow approximately 30 minutes for the valves to settle
in place. Operating the valves before this time may cause valve or piston
damage. • The valve(s) may make a tapping/ticking sound after replacement
if air is trapped in the valve lifter. Run the engine at 2000 RPM until
the air is purged from the lifter. • If the tapping/ticking does not stop, locate the defective lifter
with a stethoscope and replace. Or, remove the cylinder head cover with the
engine stopped and push the lifter down by hand with a force less than
20 kg (44 lbs) when the camshaft is on the base circle.
If clearance exists between the camshaft and the lifter the lifter is
defective and should be replaced.
