1. Remove the oil pump (see «OIL PUMP REMOVAL»(ref-371342-S42239933162010091000000) ).
2. Remove the baffle plates (see step 7 ).
3. Measure the connecting rod end play with a feeler gauge between the connecting rod and the crankshaft. Connecting Rod End Play Standard (New): 0.15-0.35 mm (0.006-0.014 in) Service Limit: 0.40 mm (0.016 in)
4. If the connecting rod end play is beyond service limit, install a new connecting rod, and recheck. If it is still beyond service limit; replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-371382-S01486799712010091000000) ).
5. Push the crankshaft firmly away from the dial indicator, and zero the dial against the end of the crankshaft. Then pull the crankshaft firmly back toward the indicator; the dial reading should not exceed the service limit. Crankshaft End Play Standard (New): 0.10-0.35 mm (0.004-0.014 in) Service Limit: 0.45 mm (0.018 in)
6. If the end play is beyond service limit, replace the thrust washers and recheck, if it is still beyond service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-371382-S01486799712010091000000) ).

1. To check main bearing-to-journal oil clearance, remove the lower block and bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(ref-371382-S01486799712010091000000) ).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. Reinstall the bearings and lower block, then torque the bolts to 29 N.m (3.0 kgf.m, 22 lbf.ft). NOTE: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection.
5. Tighten the bearing cap bolts an additional 56 °.
6. Remove the lower block and bearings again, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance No. 1, 2, 4, 5 Journals: Standard (New): 0.017-0.041 mm (0.0007-0.0016 in) Service Limit: 0.050 mm (0.0020 in) No. 3 Journal: Standard (New):0.025-0.049 mm (0.0010-0.0019 in) Service Limit: 0.055 mm (0.0022 in)
7. If the plastigage measures too wide or too narrow, remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the appropriate color code(s), and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
8. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below the current 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.
