I have a 1996 T&C LX with a 3.8 engine. It just started to sound like a piece of cardboard got caught in the fan belt and is flapping around. It only has about 120,000 miles. Could it be "Piston Slap", in need of a valve adjustment, or something else? I also want to know how much damage it could cause to drive it until I can get it looked at or serviced. Thank you.
