inspected.
MEASUREMENT
Intake Valve Clearance (cold):
0.003 - 0.008" (0.0762 - 0.2032 mm)
Exhaust Valve Clearance (cold):
0.008 - 0.014" (0.2032 - 0.3556 mm)
7. If any of the valve clearance measurements are out of
specification, remove the camshaft carriers and
camshafts and proceed with this procedure.
NOTICE
If all valve clearance measurements are within
specification, remove the camshaft carriers and
proceed to "Camshaft Installation / Timing".
8. Remove the valve tappet from a valve that was out of
specification.
NOTICE
Keep mated parts together and in order with respect to
their location in the cylinder head for assembly
purposes. Mark each component or place them in an
organized rack as you remove them.
IMPORTANT
If performing this procedure with the cylinder head
installed on the engine, make sure the crankshaft is
rotated 90 degrees from TDC so the valves don't run
into the pistons. The clearance will change (get tighter)
if the lash is set with the head disassembled compared
to after it is installed on the engine.
