I hear a sound coming from the front right. The only way to describe it is the sound a dragging chain makes. There isn't anything hanging down.

It does not do it at an idle, it does when I am in drive and foot on the accelator (not revving it). Not very often when I coast. Never when I am braking.

The engine sounds to be running fine, no issues with tranny, water, oil and fluids checked. It starts just fine, sounds like its running just fine, no knocking.

Ideas, timing belt, water pump, serptenine belt or pully. Its sounds like its definately a moving part.

Help is appreciated. I brought it in and they couldn't hear it. But as soon as I left it started making the noise again.

Thanks very much.

 

Hi , You have described the sound of a flex plate being cracked or with loose bolts ?????????? A flex plate bolts to the crankshaft & the trans. torque converter bolts to the flex plate to drive the oil pump & main shaft that drives the drive shaft & supplies the oil thru hydraullics stalls the torque converter to make movement possible & also has a ring gear used to rotate the engine to start the engine . My Guess ?????? Bud

 

What year and engine size are you having a problem with?

 

Sorry forgot the vehicle info. 2003 Dodge Grand Caravan 3.3. Whats a flax plate?

Thanks so much.

 

Update: I went out this morning and started it cold car. The sound is there, it also is there when you are stopped at a light, or in park and its idling. I couldn't hear it before because of the extra noise from other cars.

Its still sounds like a pully or something is loose.

 

I had a 3.0 that had the flex plate cracked, it made more noise when I turned the steering wheel
