Engine mechanism - Valve clearance
Valve clearance
Adjustment
1. Remove engine plastic hood components.
2. Remove ignition coil components [4G18-3705110].
3. Remove cylinder head cover components [4G18-
1003130].
4. Remove engine right bottom shield.
5. Turn crankshaft to cylinder 1 compression top dead
center position.
(a) Turn crankshaft pulley to align its groove with “o” mark on
timing chain hood.
(b) Check dot marks on camshaft timing sprocket and VVT
timing sprocket, and they should be in a line on timing chain
hood surface as shown in the diagram.
Hint: if not, turn crankshaft for one circle
again
and align the above marks.
6. Check valve clearance.
(a) Only check the valves shown in the diagram.
(1) Measure the clearance between valve tappet and cam-
shaft with plug gauge.
(2) Record valve clearance measuring value exceeding
specification, and this value will be used to determine
valve tappet thickness that needs change.

(b) Turn crankshaft for one circle
), and cylinder 4 is
turned to compression top dead center position.
(c) Only check the valves shown in the diagram. Measure valve
clearance (see step (a)).
7. Remove drive belt
Slowly turn drive belt tensioner clockwise to loosen it.
Then remove drive belt and put back drive belt tensioner slowly
and gently.

8. Remove right engine mounting assembly
(a) Remove PS oil pump reservoir and put it aside.
(b) Place wooden block between jack and engine, properly
place the jack, and then remove right engine mounting
assembly.
9. Remove drive belt tensioner device [4G18-
1300200].
Hint: operate the jack up and down to remove bolts.
10.
Adjust valve clearance.
Note: do not turn crankshaft before installing chain
tensioner.
(a) Turn crankshaft to cylinder 1 top dead center position.
(b) Align the marks on timing chain and camshaft timing
sprocket.
(c) Remove 2 bolts and chain tensioner.
(d) Fix camshaft with adjustable wrench and then loosen
the fixed bolts of exhaust camshaft timing sprocket.
Note: be careful not to damage valve lifter.
(e) As sequences shown in the diagram, loosen camshaft
bearing cover bolts on exhaust camshaft at several
times and remove the bearing cover at the same time.
(f) As shown in the diagram, remove exhaust camshaft
timing sprocket.

(g) As sequences shown in the diagram, loosen camshaft
bearing cover bolts on intake camshaft at several times
and remove the bearing cover at the same time.
(h) Hold timing chain with hands and then remove the
camshaft.
(i) As shown in the diagram, tie up the chain with bandage.
Note: be careful not to let anything fall into the
timing chain hood.
(j) Remove valve lifter.
(k) Measure the thickness of this valve lifter with
micrometer.
(1) Calculate the thickness of new valve tappet and
adjust valve clearance within specification.

Exhaust:
Hints:
New valve tappet chosen should be near the value cal-
culated as much as possible.
The thickness of valve tappet is from 5.06mm to 5.74mm,
and there is one specification every 0.02mm, therefore
there are totally 35 different dimensions to chose.
(m) As shown in the diagram, align alignment mark with tim-
ing mark on camshaft timing sprocket, and install timing
chain on the timing sprocket.
