(10) Remove dial indicator and install spark plug.
(11) Remove camshaft alignment Special Tools
6642 and install cam covers and O-rings. Tighten fas-
teners to 28 N·m (250 in. lbs.).
(12) Install timing belt covers. Refer to Timing
Belt Covers in this section.
(13) Install crankshaft damper.

the timing belt/tensioner, air has possibly entered the
tensioner.
(a) To remove air from tensioner; using a DRB
IIIt, operate the engine at speed of 1600–2000
RPM for 10 minutes. This will purge air from ten-
sioner and noise will be dissipated.
NOTE: If air is present, the tensioner will be soft
and may generate noise. This noise should disap-
pear after no more than 15 minutes of engine run-
ning time.
ROCKER ARMS AND SHAFT ASSEMBLY

arm shaft assembly on the LEFT side of the engine
has an oil passage hole from the cylinder head to
the second rocker shaft support.
