Anybody have any problems with a slight tapping in the top end of there 2.4L motor. When i start mine up first thing while the motor is cold, the motor has this lifter type tapping sound when i tap the fuel peddle, but goes away after the motor worms up. The motor only has 24,000 miles on it. After the motor worms up, its nice and tight with no problems. (Please Advise) :shock:
