1. Remove the right front wheels.
2. Remove the splash shield (see step 25 on page 5-5).
3. Remove the drive belt (see page 4-31).
4. Remove the cylinder head cover (see page 6-36).
5. Set the No. 1 piston at top dead center (TDC). The
punch mark on the variable valve timing control
(VTC) actuator and the punch mark on the exhaust
camshaft sprocket should be at the top. Align the
TDC marks on the VTC actuator and the exhaust
camshaft sprocket (see step 5 on page 6-18).
6. Disconnect the crankshaft position (CKP) sensor connector and the VTC oil control solenoid valve
connector, and remove the harness clamps (see
step 6 on page 6-18).
7. Remove the VTC oil control solenoid valve (see page 11-294).
8. Remove the crankshaft pulley (see page 6-16).
9. Support the engine with a jack and a wood block under the oil pan.
10. Remove the upper torque rod (see step 10 on page 6-18).
11. Remove the ground cable, then remove the side engine mount bracket (see step 11 on page 6-19).
12. Remove the side engine mount bracket (see step 12 on page 6-19).
13. Remove the cam chain case (see step 13 on page 6-19). 14. Measure the tensioner rod length between the
tensioner body and bottom of the flat surface
section on the tensioner rod. If the length is more
than the service limit, replace the cam chain and
the oil pump chain.
15. Check the chain case oil seal for damage. If the oil seal is damaged, replace the chain case oil seal
(see page 6-31).
16. Remove all of the old liquid gasket from the chain case mating surfaces, bolt and bolt holes.
17. Clean, and dry the chain case mating surfaces.
18. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the engine
block mating surface of the chain case, and to the
inside edge of the threaded bolt holes. Install the
component within 5 minutes of applying the liquid
gasket(seestep17onpage6-24).
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be installed 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.
19. Apply liquid gasket to the engine block upper surface contact areas on the chain case and lower
block upper surface contact areas on the chain case
(see step 18 on page 6-24).

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).

Only a scored or scratched cylinder bore must be honed. 1. Measure the cylinder bores (see page 7-16). If the engine block is to be reused, hone the
cylinders, and remeasure the bores.
2. K20Z3 engine: Remove the oil jets (see page 8-13).
3. Hone the cylinder bores with honing oil and a fine (400 grit) stone in a 60 degree cross-hatch pattern
(A). Use only a rigid hone with 400 grit or finer
stone such as Sunnen, Ammco, or equivalent. Do
not use stones that are worn or broken.
4. When honing is complete, thoroughly clean the engine block of all metal particles. Wash the
cylinder bores with hot soapy water, then dry and
oil them immediately to prevent rusting. Never use
solvent, it will only redistribute the grit on the
cylinder walls.
5. If scoring or scratches are still present in the cylinder bores after honing the engine block to the
service limit, rebore the engine block. Some light
vertical scoring and scratching is acceptable if it is
not deep enough to catch your fingernail, and does
not run the full length of the bore.
6. K20Z3 engine: Install the oil jets (see page 8-13). 1. Remove the piston from the engine block (see page
7-13).
2. Apply new engine oil to the piston pin snap rings (A), and turn them in the ring grooves until the end
gaps are lined up with the cutouts in the piston pin
bores (B).
NOTE: Take care not to damage the ring grooves.
3. Remove both snap rings (A). Start at the cutout in the piston pin bore. Remove the snap rings
carefully so they do not go flying or get lost. Wear
eye protection.

(B) by aligning the synchro ring fingers (C) with the
grooves (D) in the 5th/6th synchro hub.
15. Install the 6th gear distance collar (E) with the needle bearing (F), then install 6th gear (G).
16. Press on new angular ball bearing (A) using the 40 mm inner driver handle (B), the 30 mm inner
bearing driver attachment (C), and a press (D). 1. Measure the clearance between 1st gear (A) and
the 1st gear distance collar (B) with a feeler gauge
(C).
 If the clearance exceeds the service limit, go to step 2.
 If the clearance is within the service limit, go to step 4.
2. Measure the length of the 1st gear distance collar as shown.
 If the length is not within the standard, replace the 1st gear distance collar.
 If the length is within the standard, go to step 3.
