17. INSPECT CAMSHAFT JOURNAL OIL CLEARANCE
(a) Clean the bearing caps and camshaft journals.
(b) Place the camshafts on the cylinder head.
(c) Lay a strip of Plastigage across each of the camshaft jour-
nal.
(d) Install the bearing caps. (See page EM-59)
Torque: 16 N´m (160 kgf´cm, 12 ft´lbf)
NOTICE:
Do not turn the camshaft.
(e) Remove the bearing caps.
(f) Measure the Plastigage at its widest point.
Standard oil clearance:
Intake0.035 - 0.072 mm (0.0014 - 0.0028 in.)
Exhaust0.025 - 0.062 mm (0.0010 - 0.0024 in.)
Maximum oil clearance:
Intake0.10 mm (0.0039 in.)
Exhaust0.09 mm (0.0035 in.)
If the oil clearance is greater than maximum, replace the cam-
shaft. If necessary, replace the bearing caps and cylinder head
as a set.
(g) Completely remove the Plastigage.
(h) Remove the camshafts.
18. INSPECT CAMSHAFT THRUST CLEARANCE
(a) Install the camshafts. (See page EM-59)
(b) Using a dial indicator, measure the thrust clearance while
moving the camshaft back and forth.
Standard thrust clearance:
0.040 - 0.090 mm (0.0016 - 0.0035 in.)
Maximum thrust clearance: 0.12 mm (0.0047 in.)
If the thrust clearance is greater than maximum, replace the
camshaft. If necessary, replace the bearing caps and cylinder
head as a set.

INSTALLATION
1. PLACE CYLINDER HEAD ON CYLINDER BLOCK
(a) Place 2 new cylinder head gaskets in position on the cylin-
der block.
NOTICE:
Be careful of the installation direction.
(b) Place the 2 cylinder heads in position on the cylinder head
gaskets.
2. INSTALL 12 POINTED HEAD CYLINDER HEAD BOLTS
HINT:
The cylinder head bolts are tightened in 2 progressive
steps (steps (c) and (e)).
If any bolt is broken or deformed, replace it.
(a) Apply a light coat of engine oil on the threads and under
the heads of the cylinder head bolts.
(b) Install the plate washer to the cylinder head bolt.
(c) Install and uniformly tighten the cylinder head bolts on
each cylinder head in several passes and in the sequence
shown, then repeat for the other side, as shown.
Torque: 54 N´m (550 kgf´cm, 40 ft´lbf)
If any of the cylinder head bolts does not meet the torque speci-
fication, replace the cylinder head bolt.
(d) Mark the front of the cylinder head bolt head with paint.
(e) Retighten the cylinder head bolts by 90° in the numerical
order shown.
(f) Check that the painted mark is now at a 90° angle to the
front.

3. INSTALL RECESSED HEAD CYLINDER HEAD BOLTS
(a) Apply a light coat of engine oil on the threads and under
the heads of the cylinder head bolts.
(b) Using an 8 mm hexagon wrench, install the cylinder head
bolt on each cylinder head, then repeat for the other side,
as shown.
Torque: 18.5 N´m (185 kgf´cm, 13 ft´lbf)
4. ASSEMBLE EXHAUST CAMSHAFTS
(a) Mount the hexagonal wrench head portion of the cam-
shaft in a vise.
NOTICE:
Be careful not to damage the camshaft.
(b) Install the camshaft gear spring (1) and camshaft sub-
gear (2).
HINT:
Attach the pins on the gears to the gear spring ends.
(c) Install the wave washer (3).
(d) Using snap ring pliers, install the snap ring.
