Here are some additional tips for torquing main bearing caps:
* Use a quality torque wrench that is accurate within ±2%.
* Apply a small amount of oil to the threads of the bolts before installing them.
* Tighten the bolts in a smooth, even motion. Do not jerk or apply excessive force.
* Recheck the torque on the bolts after the engine has been running for a few minutes.
By following these steps, you can ensure that the main bearing caps are properly torqued and that your engine will operate smoothly and efficiently.
