Ratlling noise front

Nissan had a problem with the exhaust bracket being cracked or broken

I would need to know what vehicle this is? 4 Cylinder. V6? 3.0? There are a few things it could be,

If the Engine is Moving, it could be hitting something so I would check the Motor Mounts (Happens quite Frequently on Taurus)

Check the Tension of your Serpentine Belt

try looking at motor mounts.

Thats exhaust ratlle internal it something with thhe exhaust from heat shield to exhaust catalytic internal

Hi quintincoetz,

If your noise is a ratlling noise, more like a chain top end noise, then I would recommend first checking your oil level and condition. If the oil level is ok, you can remove the oil cap while the engine is running and look for oil lubrication on the valve train. It will probably splatter out a little. The most common cause of the noise is a failing timing chain tensioner. It allows the chain to have too much slack and slap against the guild rails. The tensioner is not too hard to replace and not very expensive either. If you have more than 100k miles, it is recommended to replace anyways. If your noise is more low pitched and more like a knock, I would recommend having a technician look at further.

which engine..2.3 quad or a 2.2

I had the same problem on my 2006 Lucerne and it was the engine mount located on the front of the vehicle behind the radiator.

had the same issue, had someone look and it seems the noise was caused by heat shield being loose covering exhaust system. Have that checked out.

Hi,thereis a metal shield on top of your muflers ,they get to close and make those ratlleing noises ,you can check this and if this is the problem replace the ruber mounts or try pulling the muffler down....
