2) Install camshaft cap.
(1) Apply fluid packing sparingly to back of front
camshaft cap shown in the figure.
CAUTION:
Do not apply fluid gasket excessively. Failure to
do so may cause excess fluid gasket to come
out and flow toward camshaft journal, resulting
burning stuck of engine.

(2) Apply engine oil to cap bearing surface and
install cap on camshaft.
(3) Tighten the camshaft cap bolts in the nu-
merical sequence shown in the figure.
Tightening torque:
16 N·m (1.6 kgf-m, 11.6 ft-lb)
(4) Tighten the front camshaft cap bolts in the
numerical sequence shown in the figure.
Tightening torque:
9.8 N·m (1.0 kgf-m, 7.2 ft-lb)
3) Install rocker cover.
(1) Apply fluid gasket sparingly to matching sur-
face of cylinder heads and rocker covers shown
in the figure.
CAUTION:
Do not apply fluid gasket excessively. Doing so
may cause excess fluid gasket to come out and
flow toward camshaft journal, resulting burning
stuck of engine.
