SOURCE: hi do i need to replace the main bearing and the conrod bearing bolts on the opel corsa 6W engine 2006 model

it is good mechanical practice to replace all bolts that are operating under tension. That includes con rod bolts , big end bolts fly wheel bolts , head studs and crank shaft bolt. Some manuals recommend the replacement of cam shaft sprocket bolts as well. This practice is recommended where the engine is driven at high rpms. It is recommended practice because the tension effect actually twists the bolt and this combined with the tensional stress makes the bolts prone to failure. As it adds considerably to the cost many mechanics do not follow the practice but will charge for the new bolts as well.

Fig. Fig. 4: Main bearing cap bolt tightening sequence on 3E and 3E-E engines

  1. Fit the upper bearings halves into the block and position the lower bearing halves in the bearing caps.
  2. Place the crankshaft into the engine block, making sure it fits exactly into its mounts.
  3. Install the upper thrust washers on the center main bearing with the oil grooves facing outward.
  4. Install the main bearing caps and the lower thrust washers in the proper sequence. Make sure the arrows on the caps point towards the front (pulley end) of the motor.
  5. Tighten the cap bolts to specification in three passes. On 3E and 3E-E engines, use the correct sequence.
  6. Double check the end-play of the crankshaft by repeating the procedure described earlier.
  7. Turn the crankshaft through one or two full clockwise rotations, making sure that it turns smoothly and evenly with no binding.
  8. Attach the piston rods, following procedures given earlier in this section. Remember that the rod caps must be reinstalled in their original positions.
  9. Install a new rear main oil seal into the retainer and install the retainer onto the block. Tighten the bolts to specification.
  10. Install the rear end plate on the engine.
  11. Install either the driveplate (automatic) or the flywheel (manual), observing the matchmarks made during removal.
  12. If equipped with a manual transaxle, reinstall the clutch disc and pressure plate.
  13. Install the oil pump.
  14. Install the oil strainer and oil pan, using new gaskets.
  15. Rotate the engine into its upright position and continue reassembly of the timing belt, idler pulley and covers.
  16. Reinstall the engine in the car, following procedures outlined earlier in this section.
