CAMSHAFT OIL CLEARANCE
Clean off any oil from the journals of the camshaft
holders, cylinder head and camshaft.
Put the camshaft onto the cylinder head and lay a
strip of plastigauge lengthwise on each camshaft
journal.
NOTE:
• Do
not block any
oil
passages with
the
plastigauge.
• Do not rotate the camshaft during inspection.
Carefully install the camshaft holder and tighten the
camshaft holder bolts and nuts to the specified
torque in a crisscrQss pattern in several steps.
TORQUE: 23 N·m (2.3 kgf'm, 17Ibf.ft)
Remove the camshaft holder and measure the
width of each plastigauge.
The widest thickness determines the oil clearance.
SERVICE LIMIT: 0.16 mm (0.006 in)
When the service limit is exceeded, replace the cam
shaft and recheck the oil clearance.
Replace the cylinder head and camshaft holder if
the oil clearance still exceeds the service limit.
