7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below that one), and check again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over.

   If the block is to be reused, hone the cylinders and remeasure the bores.

2. 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.
   

   

   
   
3. 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.
   
4. If scoring or scratches are still present in the cylinder bores after honing to the service limit, rebore the cylinder 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.

5. Install the bearing halves in the cylinder block and connecting rods.
   
6. Apply a coat of engine oil to the main bearings and rod bearings.
   
7. Hold the crankshaft so rod journal No. 2 and rod journal No. 3 are straight up, and lower the crankshaft into the block.
   
8. Install the thrust washers (A) in the No. 4 journal of the cylinder block.
   

   

   
   
9. Apply 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 cap, then install the caps and 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 cap, then install the caps and bolts finger-tight.
    
12. Tighten the connecting rod bolts to 20 N·m (2.0 kgf·m, 14 lbf·ft).
    
13. Tighten the connecting rod bolts an additional 90°.
    
14. Remove old liquid gasket from the lower block mating surfaces, bolts and bolt holes.
    
15. Clean and dry the lower block mating surfaces.
    
16. Apply liquid gasket, P/N 08C70-K0234M, 08C70-K0334M or 08C70-X0331S, evenly to the cylinder block mating surface of the lower block and to the inner threads of the bolt holes.
    

    NOTE: Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. Instead, reapply liquid gasket after removing old residue.

17. Put the lower block on the cylinder block.
    
18. Tighten the bearing cap bolts in sequence to 29 N·m (3.0 kgf·m, 22 lbf·ft).
    

    

    
    
19. Tighten the bearing cap bolts an additional 56°.
    
20. Tighten the 8 mm bolts in sequence to 22 N·m (2.2 kgf·m, 16 lbf·ft).
    

    

    
    
21. Use the special tools to drive a new oil seal squarely into the block to the specified installed height.
    

    

    
    
22. Measure the distance between the crankshaft (A) and oil seal (B).
    

Oil Seal Installed Height: 5.5 - 6.5 mm

(0.22 - 0.26 in.)

23. Install the baffle plates.
    

    

    
    
24. Install the oil pump (see page 08-16) .
    
25. Install the oil pan (see page 07-27) .
    
26. Install the cylinder head (see page 06-40) .
    
27. Install the transmission:
    

    Manual transmission (see page 13-10) .

    Automatic transmission (see page 14-143) .

28. Install the engine assembly (see page 05-10) .
    

Oil Pan Installation07-27

1. Remove old liquid gasket from the oil pan mating surfaces, bolts, and bolt holes.
   
2. Clean and dry the oil pan mating surfaces.
   
3. Apply liquid gasket, P/N 08C70-K0334M or 08C70-X0331S, evenly to the cylinder block mating surface of the oil pan and to the inner threads of the bolt holes.
   

   NOTE: Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. Instead, reapply liquid gasket after removing old residue.

   

   
   

4. Install the oil pan.
   
5. Tighten the bolts in two or three steps. In the final step, tighten all bolts, in sequence, to 12 N·m (1.2 kgf·m, 8.7 lbf·ft).
