22. REMOVE WIRE HARNESS CLAMP BOLT FROM INTAKE MANIFOLD






23. MEASURE CAMSHAFT THRUST CLEARANCE
Using a dial gauge, measure thrust clearance while moving the camshaft back and forth.
Standard thrust clearance: 0.08-0.18 mm (0.0031 - 0.0071in)
Maximum thrust clearance: 0.25 mm (0.0098 in.)
If clearance is greater than maximum, replace the head and/or camshaft.






24. REMOVE CYLINDER HEAD
(a) Remove and loosen the head bolts gradually in three passes in the numerical order shown.

CAUTION: Head warpage or cracking could result from removing the head bolts out order.

NOTE: Some engines have head bolts with smoothly ground head surfaces.






(b) Lift the head from the dowels on the cylinder block and place it on the wooden blocks on a each.






If the cylinder head is difficult to lift off, pry with a bar between the head and block projection.

NOTE: Be careful not to damage the cylinder block or cylinder head contact surfaces.

(c) Remove the cylinder head gasket.
