The motor should not be run at less than 2500 rpm for a minimum of 20 minutes. If a problem develops, shut the motor down and fix it, then resume break-in. The main sources of camshaft lubrication is oil thrown off of the rods and crankshaft, drain back from the oil rings and oil blowing around inside the crankcase (this is known as "windage"). At idle, the crank isn't spinning fast enough to provide sufficient oil splash to the camshaft/lifters for proper break in protection. |
