it stopes after one minute it only has 65,000 miles on it and i use 10w30 oil every 3,000 miles.love the van but dodge messed this motor up.

could be piston slap...on newer vehicles, the pistons were made with a short side skirt causing them to have a bit of movement when cold. as long as it goes away, i would not worry about it.
