Mitsubishi Lancer 2005: Noisy start-up

THERE shouldn't be any rattling noises when you start a car, whether it's a Lancer or any other brand. The noise could come from a valve lifter that is taking an unusual amount of time to pump up.  Sludge in the engine could be affecting the supply of oil to the lifters. Or the problem could be caused by incorrect oil used at service or, in the worst case, a lack of proper servicing.
