CAUTION:
D Don't turn camshafts or start engine (i.e., valves
should not be operated) for about half an hour after re-
installing hydraulic valve lash adjusters and cam-
shafts. As it takes time for valves to settle in place, op-
erating engine within half an hour after their installa-
tion may cause interference to occur between valves
themselves or valves and piston.
D If air is trapped in valve lash adjuster, valve may make
tapping sound when engine is operated after valve
lash adjuster is installed. In such a case, run engine
for about half an hour at about 2,000 – 3,000 r/min.,
and then air will be purged and tapping sound will
cease. Should tapping sound not cease, it is possible
that valve lash adjuster is defective. Replace it if de-
fective.
If defective adjuster can't be located by hearing
among 24 of them, check as follows.
1) Stop engine and remove cylinder head cover.
2) Push adjuster downward by hand (with less than 20
kg or 44 lbs force) when cam crest is not on adjuster
to be checked and check if clearance exists be-
tween cam and adjuster. If it does, adjuster is defec-
tive and needs replacement.
