1. Measure the diameter of each connecting rod bolt

at point A and point B.

2. Calculate the difference in diameter between point

A and point B.

3. If the difference in diameter is out of specification,

replace the connecting rod bolt.

• Driver 07749-0010000
• Attachment, 24 x 26 mm 07746-0010700
• Oil seal driver attachment 96 07ZAD-PNAA100

1. M/T model: Install the crankshaft end bushing

when replacing the crankshaft.
Using the driver and the attachment, 24 x 26 mm
drive in the crankshaft end bushing until the driver
and the attachment bottom against the crankshaft.

2. Check the connecting rod bearing clearance with

plastigage (see page 7-8).

3. Check the main bearing clearance with plastigage

(see page 7-6).

4. Install the bearing halves in the engine block and

the connecting rods.

5. Apply new engine oil to the main bearings and the

rod bearings.

6. Hold the crankshaft so rod journal No. 2 and rod

journal No. 3 are straight up, then lower the
crankshaft into the engine block.

7. Apply new engine oil to the thrust washer surfaces.

Install the thrust washers (A) in the No. 4 journal of
the engine block.

8. Inspect the connecting rod bolts (see page 7-25).

9. Apply new engine oil to the threads of the

connecting rod bolts.

10. Seat the rod journals into connecting rod No. 1 and

connecting rod No. 4. Line up the mark (B) on the
connecting rod and the cap, then install the caps
and the bolts finger-tight.

11. Rotate the crankshaft clockwise, and seat the

journals into connecting rod No. 2 and connecting
rod No. 3. Line up the mark on the connecting rod
and the cap, then install the caps and the bolts
finger-tight.

12. Tighten the connecting rod bolts to 20 N·m

(2.0 kgf·m, 14 lbf·ft) (K20Z2 engine) or 29 N·m
(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.

17. Install the main bearings, then put the lower block

on the engine block.

18. Apply new engine oil to the threads of the bearing

cap bolts.

19. Tighten the bearing cap bolts, in sequence, to

29 N·m (3.0 kgf·m, 22 lbf·ft).

20. Tighten the bearing cap bolts an additional 56 °.

21. Tighten the 8 mm bolts, in sequence, to 22 N·m

(2.2 kgf·m, 16 lbf·ft).

22. Apply a light coat of new engine oil around the

crankshaft oil seal.

23. Apply a light coat of new engine oil to the

crankshaft and the lip of the crankshaft oil seal.

24. Use the driver and the oil seal driver attachment 96

to drive a new oil seal squarely into the engine
block to the specified installed height.

26. Install the baffle plates.

27. Install the oil pump (see page 8-21).

28. Install the oil pan (see page 7-29).

29. Install the cylinder head (see page 6-62).

30. M/T model: Install the flywheel (see page 12-21),

the clutch disc (see page 12-23), and the pressure
plate (see page 12-23).

31. A/T model: Install the drive plate (see page 14-242).

32. Install the transmission:

• Manual transmission (see page 13-14)
• Automatic transmission (see page 14-242)

33. Install the engine assembly (see page 5-13).

NOTE: Whenever any crankshaft or connecting rod
bearing is replaced, it is necessary after
reassembly to run the engine at idle speed until it
reaches normal operating temperature, then
continue to running it for about 15 minutes.
