b. Install and uniformly tighten the 14 main bearing cap bolts, in several passes, in the sequence shown.
Torque: 45 Nm (450 kgf-cm, 33 ft. lbs.)
If any one of the main bearing cap bolts does not meet the torque specification, replace the main bearing cap bolt.
c. Mark the front of the main bearing cap bolt head with paint.
d. Retighten the main bearing cap bolts 90° in the numerical order shown.
e. Check that the painted mark is now at a 90° angle to the front.
f. Check that the crankshaft turns smoothly.

b. Install the connecting rod cap with by aligning the dowel pin to the corresponding hole.
12. INSTALL CONNECTING ROD CAP BOLTS
HINT:
- The connecting rod cap bolts are tightened in 2 progressive steps (steps b. and d.).
- If any of the connecting rod bolts break or deform, replace them.
a. Apply a light coat of engine oil on the threads and under the heads of the connecting rod cap bolts.
b. Install and alternately tighten the bolts of the connecting rod cap in several passes.
Torque: 30 Nm (300 kgf-cm, 22 ft. lbs.)
If any one of the connecting rod cap bolts does not meet the torque specification, replace the cap bolt.
c. Mark the front of the connecting rod cap bolt with paint.
d. Retighten the connecting rod cap bolts 90° in the numerical order shown.
e. Check that the painted mark is now at a 90 angle to the front.
f. Check that the crankshaft turns smoothly.
13. CHECK CONNECTING ROD THRUST CLEARANCE
14. INSTALL REAR OIL SEAL RETAINER
a. Remove any old packing (FIPG) material and be careful not to drop any oil on the contact surfaces of the retainer and cylinder block.
- Using a razor blade and gasket scraper, remove all the old packing (FIPG) material from the gasket surfaces and sealing groove.
- Thoroughly clean all components to remove all debris.
- Using a non-residue solvent, clean both sealing surfaces.
b. Apply seal packing to the retainer as shown in the illustration.
