Can anyone say what kind of damage is done to effectively every internal moving part of an engine when it is operated before reaching running temp?
Are the amounts of expansion each part experiences enough to create brief periods of rapid and/or extreme wear due to increased play when not up...
When installing new oe-spec front brake rotors, and the disc retaining screws are properly torqued, is it necessary to check the runout? If so, is the integrity of the hub what we are assessing?
