I have a 2005 Grand Caravan with 119,000 miles. It has recently started to have a weird engine noise. It almost has a "diesel" engine sound to it. Not a knock or a tic, but like a swishy click. Does that make any sense? Just curious if anyone has any ideas as to where I should start looking. T

 

Has anything else changed about the way the vehicle runs? Have you stuck your head under the hood and attempted to locate a general direction where the new noise is coming from?
