B: INSPECTION
1. CAMSHAFT
1) Measure the bend, and repair or replace if necessary.
Limit:
0.020 mm (0.0008 in)
2) Check journal for damage and wear. Replace if faulty.
3) Measure outside diameter of camshaft journal. If the
journal diameter is not as specified, check the oil clear-
ance.

B2M1216
4) Measurement of the camshaft journal oil clearance
(1) Clean the bearing caps and camshaft journals.
(2) Place the camshafts on the cylinder head. (Without
installing valve rocker.)
(3) Place plastigauge across each of the camshaft
journals.
(4) Install the bearing caps.
CAUTION:
Do not turn the camshaft.
(5) Remove the bearing caps.
(6) Measure the widest point of the plastigauge on
each journal.
If the oil clearance exceeds the limit, replace the cam-
shaft. If necessary, replace the camshaft caps and cyl-
inder head as a set.
Standard oil clearance:
0.037—0.072 mm (0.0015—0.0028 in)
Limit:
0.10 mm (0.0039 in)
(7) Completely remove the plastigauge.

5) Check cam face condition; remove minor faults by
grinding with oil stone. Measure the cam height H; replace
if the limit has been exceeded.

6) Measure the thrust clearance of camshaft with dial
gauge. If the clearance exceeds the limit, replace caps and
cylinder head as a set. If necessary replace camshaft.

1) Camshaft installation
Apply engine oil to cylinder head at camshaft bearing loca-
tion before installing camshaft. Install camshaft so that
rocker arm is close to or in contact with“base circle”of cam
lobe.
CAUTION:
When camshafts are positioned as shown in figure,
camshafts need to be rotated at a minimum to align
with timing belt during installation.
Right-hand camshaft need not be rotated when set
at position shown in figure.
Left-hand intake camshaft: Rotate 80°clockwise.
Left-hand exhaust camshaft: Rotate 45°counter-clock-
wise.

2) Camshaft cap installation
(1) Apply fluid packing sparingly to cap mating surface.
CAUTION:
Do not apply fluid packing excessively. Failure to do so
may cause excess packing to come out and flow
toward oil seal, resulting in oil leaks.
Fluid packing:
THREE BOND 1215 or equivalent
G2M0753
(2) Apply engine oil to cap bearing surface and install
cap on camshaft as shown by identification mark.
(3) Gradually tighten cap in at least two stages in the
numerical order shown in figure, and then tighten to
specified torque.
(4) Similarly, tighten cap on exhaust side.
After tightening cap, ensure camshaft rotates only
slightly while holding it at“base”circle.

3) Inspect for valve clearance.
Measure valve clearances using thickness gauge.
2-2 [07A2].>
If necessary, adjust valve clearances.

4) Camshaft oil seal installation
Apply grease to new oil seal lips and press onto front end
of camshaft by using ST1 and ST2.
CAUTION:
Use a new oil seal.

5) Rocker cover installation
(1) Install gaskets on rocker cover.
Install peripheral rocker cover gaskets.
(2) Apply fluid packing to four front open edges of
peripheral gasket.
Fluid packing:
