  1. With a manual transmission, install the crankshaft pilot bushing when replacing the crankshaft. Using the special tools, drive in the crankshaft pilot bushing until the special tools bottom against the crankshaft.
  2. Check the connecting rod bearing clearance with plastigage (see «CONNECTING ROD BEARING REPLACEMENT»(ref-218777-S37111044942006021000000) ).
  3. Check the main bearing clearance with plastigage (see «CRANKSHAFT MAIN BEARING REPLACEMENT»(ref-218777-S33954396882006021000000) ).
  4. Inspect the connecting rod bolts (see «IF THE CRANKSHAFT IS NOT INSTALLED»(ref-218777-S19847326352006021000000) ).
  5. Install the bearing halves in the engine block and connecting rods.
  6. Apply a coat of new 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, then lower the crankshaft into the block.
  8. Install the thrust washers (A) in the No. 4 journal of the engine 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. Tightening Torque K20A3 Engine: 20 N.m (2.0 kgf.m, 14 lbf.ft) K20A2, K20Z1 Engines: 29 N.m (3.0 kgf.m, 22 lbf.ft)
  13. 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 4 . of the procedure. Do not loosen it back to the specified angle.
  14. Remove all of the 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 08717-0004, 08718-0001, 08718-0002, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the lower block. NOTE: Do not install components if too much time has passed after applying the liquid gasket (for P/N 08718-0002, no more than 4 minutes, for all others, no more than 5 minutes). Instead, remove the old residue and reapply the liquid gasket.
  17. Put the lower block on the engine 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).
  23. Install the baffle plate.
  24. Install the oil pump (see «OIL PUMP INSTALLATION»(ref-218779-S32332089802006021000000) ).

  27. A/T model: Install the drive plate (see «DRIVE PLATE REMOVAL AND INSTALLATION»(ref-218795-S23423725222006021000000) ), then install the transmission (see «TRANSMISSION INSTALLATION»(ref-218795-S20832935452006021000000) ).
  28. M/T model: Install the flywheel (see «FLYWHEEL INSPECTION»(ref-218793-S03814704012006021000000) ), then install the clutch disc and pressure plate (see «CLUTCH DISC AND PRESSURE PLATE INSTALLATION»(ref-218793-S01623234022006021000000) ). Install the transmission (see «TRANSMISSION INSTALLATION»(ref-218795-S20832935452006021000000) ).
  29. Install the engine assembly (see «ENGINE INSTALLATION»(ref-218775-S00985765942006021000000) ). NOTE: Whenever any crankshaft or connecting rod bearing is replaced, it is necessary after reassembly to run the engine at idling speed until it reaches normal operating temperature, then continue to run it for about 15 minutes.

  1. Remove all of the 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 08717-0004, 08718-0001 08718-0002, 08718-0003 or 08718-0009, evenly to the engine block mating surface of the oil pan. NOTE: Do not install components if too much time has passed after applying the liquid gasket (for P/N 08718-0002, no more than 4 minutes, for all others, no more than 5 minutes). Instead, remove the old residue and reapply the liquid gasket.
  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). Wipe off the excess liquid gasket on the each side of crankshaft pulley and flywheel/drive plate. NOTE: Wait at least 30 minutes before filling the engine with oil. Do not run the engine for at least 3 hours after installing the oil pan.
  6. If the engine is still in the vehicle, install the subframe. 1 Install the subframe. Align the reference lines on the subframe with the bolt head center, then tighten the bolts (see step 4 on «ENGINE INSTALLATION»(ref-218775-S00985765942006021000000) ). 2 Install the automatic transmission (ATF) filter mounting bolt (see step 24 on «ENGINE INSTALLATION»(ref-218775-S00985765942006021000000) ). 3 Tighten the rear mount mounting bolts (see step 5 on «ENGINE INSTALLATION»(ref-218775-S00985765942006021000000) ). 4 Tighten the new front mount mounting bolt (see step 11 on «ENGINE INSTALLATION»(ref-218775-S00985765942006021000000) ). 5 Connect the suspension lower arm ball joints (see step 10 on «KNUCKLE/HUB/WHEEL BEARING REPLACEMENT»(ref-218799-S39724779852006021000000) ).
