Valve Clearance
Adiustment
Adjust the valves only when the cylinder head tempera-
ture is less than 100"F (38"C).
1. Remove the cylinder head cover.
Remove the middle cover (see page 6-11).
Set the No. 1 piston at TDC. The "UP" mark on the
pulleys should be at the top, and the TDC marks on
the pulleys should align with the pointers on the back
POINTERPOINTER
Adjust the valves on No. 1 cylinder.
Intake: 0.08 - 0.12 mm (0.003 - 0.005 inl
Exhaust: 0.16 - 0.20 mm (0.006 - 0.008 in)
Loosen the locknut, and turn the adiustment screw
until the feeler gauge slides back and forth with a
slight amount of drag.

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
YA8845-2A 7/8" auachment). Use approved eye protec-
tion.
1. Turn the crankshaft so that the No. 1 and the No. 4
pistons are at top dead center (TDC).
2. Remove the cylinder head cover.
3. Remove the distributor.
4. Loosen and disconnect the timing belt from the
camshaft pulleys.
5. Remove the camshaft holder bolts. then remove the
camshaft holders, the camshafts and rocker arms.

6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the top hole of the
two uprights,
at.
9.
Select the 7/8 in. diameter long compressor attach-
ment, and fasten the attachment to the front hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing the
springs and removing the valve keepers.
10. Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
head.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown,

the two uprights.
Select the 7/8 in. diameter short compressor attach
ment, and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insert an air adaptor
