NOTE: Keep the cam chain away from magnetic fields.
 Before doing this procedure, check that the variable valve timing control (VTC) actuator is locked by
turning the VTC actuator counterclockwise. If not
locked, turn the VTC actuator clockwise until it stops,
then recheck it. If it is still not locked, replace the VTC
actuator.
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
2. Set the camshafts to TDC. The punch mark (A) on the VTC actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. To hold the intake camshaft, insert a camshaft lock
pin (07AAB-RWCA120) (A) into the maintenance
hole in camshaft position (CMP) pulse plate A (B)
and through No. 5 rocker shaft holder (C).
4. To hold the exhaust camshaft, insert a camshaft lock pin (A) into the maintenance hole in CMP pulse
plate B (D) and through No. 5 rocker shaft holder
(C).
5. Install the cam chain on the crankshaft sprocket with the colored link plate (A) aligned with the mark
(B) on the crankshaft sprocket.

1. Remove the cam chain (see page 6-18).
2. Hold the exhaust camshaft with an open-end
wrench, then loosen the variable valve timing
control (VTC) actuator mounting bolt and the
exhaust camshaft sprocket mounting bolt.
3. If the VTC actuator is reused, do these steps. –1 Remove the intake camshaft, and seal theadvance holes and retard holes in the No. 1
camshaft journal with tape (see step 6 on page
6-11).
–2 Punch a hole in the tape over one of the advance holes (see step 7 on page 6-11).
–3 Apply air to the advance hole to release the lock (see step 8 on page 6-11).
–4 Remove the tape from the No. 1 camshaft journal.
4. Remove the VTC actuator and the exhaust camshaft sprocket. 1. Install the variable valve timing control (VTC)
actuator and exhaust camshaft sprocket.
NOTE: Install the VTC actuator to unlock position.
2. Apply new engine oil to the threads of the VTC actuator mounting bolt and the exhaust camshaft
mounting bolt, then install them.
3. Hold the exhaust camshaft with an open-end wrench, then tighten the mounting bolts.
4. Hold the exhaust camshaft with an open-end wrench, and turn the VTC actuator clockwise until
you hear it click. Make sure to lock the VTC actuator
by turning it.
5. Install the cam chain (see page 6-21).

9. Apply a thin coat of new engine oil to the outside of
the new valve guide. Install the guide from the
camshaft side of the head, use the valve guide
driver to drive the guide in to the specified installed
height (A) of the guide (B). If you have all 16 guides
to do, you may have to reheat the head. 10. Coat both valve guide reamer, 5.5 mm and the
valve guide with cutting oil.
11. Rotate the reamer clockwise to the full length of the valve guide bore.
12. Continue to rotate the reamer clockwise while removing it from the bore.
13. Thoroughly wash the guide in detergent and water to remove any cutting residue.
14. Check the clearances with a valve (see page 6-55). Verify that a valve slides into the intake and
exhaust valve guides without sticking.
15. Inspect the valve seating, if necessary renew the valve seat using a valve seat cutter (see page 6-58).

(3.0 kgf·m, 22 lbf·ft) (K20Z3 engine).
13. Tighten the connecting rod bolts an additional 90 °. NOTE: Remove the connecting rod bolt if you
tightened it beyond the specified angle, and go
back to step 8 of the procedure. Do not loosen it
back to the specified angle.
14. Remove all of the old liquid gasket from the lower block mating surfaces, the bolts, and the bolt holes.
15. Clean, and dry the lower block mating surfaces.
16. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the engine
block mating surface of the lower block, and to the
inside edge of the threaded bolt holes. Install the
component within 5 minutes of applying the liquid
gasket.
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be install within 4 minutes.
 If too much time has passed after applying the liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket.
Apply liquid gasket
along the broken line.
