15. Torque the connecting rod bolts to 9.8 Nm (1.0 kg-m, 7 lb-ft).

16. 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 11 of the procedure. Do not loosen it back to the specified angle.






17. Install the main bearing caps with facing the arrows (A) the cam chain side on the bearing cap bridge.





18. Remove all of the old liquid gasket from the bearing cap bridge/No. 5 main bearing cap mating surfaces.

19. Clean and dry the bearing cap bridge/No. 5 main bearing cap mating surfaces.

20. Apply liquid gasket (P/N 08717-0004, 08718-0003, 08718-0004, or 08718-0009) to the engine block mating surface of the bearing cap bridge/No. 5 main bearing cap. Install the component within 5 minutes of applying the liquid gasket.

NOTE:

- Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
- 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.





21. Put the bearing cap bridge on the engine block.

22. Apply new engine oil to the threads and the flange of the bearing cap bolts.

23. Torque the bearing cap bolts in sequence to 25 Nm (2.5 kg-m, 18 lb-ft).






24. Tighten the bearing cap bolts an additional 40 °.





25. Clean the excess liquid gasket off the engine block.

26. Clean and dry the crankshaft oil seal housing.

27. Apply a light coat of new engine oil to the lip of the crankshaft oil seal.

28. Using the driver handle (A) and the oil seal driver attachment, 96 mm (B), to drive a new crankshaft oil seal squarely into the block to the specified installed height.






29. Measure the distance between the cylinder block (A) and the crankshaft oil seal (B).










30. Install the oil pump (A) with a new O-ring (B).





31. Install the oil screen (C) with a new gasket (D).

32. Install the oil pan Engine Oil Pan Installation.

33. Install the cylinder head Cylinder Head Installation.

34. Connect the CKP sensor connector (A), then install the CKP sensor cover (B).





35. Install the harness cover (C).

36. M/T model: Install the flywheel, the clutch disc, and the pressure plate.

37. A/T model: Install the drive plate Service and Repair.

38. Install the transmission.

- M/T model Manual Transmission Installation
- A/T model Automatic Transmission Installation

39. Install the engine/transmission Engine Installation.

NOTE: When any crankshaft main or connecting rod bearing is replaced, run the engine at idle until it reaches normal operating temperature, then continue to run it for about 15 minutes.
