justing screws backed off before installation.
1. After wiping down the camshaft and journals in the
cylinder head, lubricate both surfaces and install the
camshafts and rubber caps.
NOTE: Apply liquid gasket around the rubber cap.
2. Turn the camshaft until its keyway is facing up. (No. 1
cylinder TDC).
3. Set a new O-ring and a dowel pin in the oil passage
of the No. 1 camshaft holder.
4. Install the camshaft seals with the open side
(spring) facing in.

13. Install the timing belt (see page 6-18 (’91-’93) or (’94-’96)) .
14. Adjust the valve clearance (see page 6-9 (’91-’93) or (’94-’96)).
15. Inspect the rocker arms (see pages 6-7(’91-’93) or (’94-’96),
8 (’91-’93) or (’94-’96)).
16. Install the head cover gasket in the groove of the
cylinder head cover. Seat the recesses for the
camshaft first, then work it into the groove around
the outside edges.
NOTE:

17. Apply liquid gasket to the head cover gasket at the
eight corners of the recesses.
NOTE:
• Use liquid gasket, Part No. 08718-0001.
• Check that the mating surfaces are clean and dry
before applying liquid gasket.
• Do not install the parts if five minutes or more
have elapsed since applying liquid gasket. Instead,
reapply liquid gasket after removing old residue.
• After assembly, wait at least 20 minutes before
filling the engine with oil.
Apply liquid gasket to
the shaded areas.
18. When installing the cylinder head cover, hold the
head cover gasket in the groove by placing your fin-
gers on the camshaft contacting surfaces (top of the
semicircles).
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
NOTE:
• Before installing the cylinder head cover, clean
the cylinder head contacting surfaces with a
shop towel.
• Do not touch the parts where liquid gasket was
applied.
• Replace the washer when damaged or deterio-
