It does not matter whether the torque is 10lbs ft or 1000lbs ft, the true torque value will be affected. There is a reason why so many people strip the thread in their sumps or crack the sump.When people put the sump bolt back in, even if they have cleaned the thread on the bolt, there is still oil on the thread in the sump.
