Take it easy on it until it reaches operating temp. I try not to let mine go over 2.5k until it gets up to operating temperature. When engines are cold, they have more friction due to the "shrinkage" (sp) of metal parts until they expand to their designed operating tolerances. Also, the oil pressure is very high until it is heated and thins out. Look at your oil pressure gauge when your engine is cold, it probably doesn't come down from being pegged until your engine is warm. I don't like to stress major ($$$) components unless , maybe it is an emergency situation.
