1. Remove the oil pump (see «OIL PUMP OVERHAUL»(ref-424873-S19916578242011100100000) ).
2. Remove the baffle plate (see step 10 .
3. Measure the connecting rod end play with a feeler gauge (A) between the connecting rod (B) and the crankshaft (C). Connecting Rod End Play Standard (New): 0.15-0.35 mm (0.0059-0.0138 in) Service Limit: 0.40 mm (0.0157 in)
4. If the connecting rod end play is beyond the service limit, install a new connecting rod, and recheck. If it is still beyond the service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-424909-S26519311192011100100000) ).
5. Push the crankshaft firmly away from the dial indicator by prying, and zero the dial against the end of the crankshaft. Then pull the crankshaft firmly back toward the indicator by prying; the dial reading should not exceed the service limit. Crankshaft End Play Standard (New): 0.10-0.35 mm (0.0039-0.0138 in) Service Limit: 0.45 mm (0.0177 in)
6. If the crankshaft end play is beyond the service limit, replace the thrust washers and recheck. If it is still beyond the service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-424909-S26519311192011100100000) ).

1. To check the main bearing-to-journal oil clearance, remove the lower block and the bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(ref-424909-S26519311192011100100000) ).
2. Clean each main journal and the bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. Reinstall the bearings and the 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 48°.
6. Remove the lower block and the 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 (0.00067-0.00161 in) Service Limit: 0.050 mm (0.00197 in) No. 3 Journal: Standard (New): 0.025-0.049 mm (0.00098-0.00193 in) Service Limit: 0.055 mm (0.00217 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 (see «CRANKSHAFT AND PISTON REMOVAL»(ref-424909-S26519311192011100100000) ).
