Hello, I have a 2013 LX570 141K miles. I get this weird rattling noise at low RPMs. I'm using 0w20 oil and overall there are no issues with drivability and this noise is very annoying. It usually happens when I'm going really slow or idling like at a drive-through or something but it might even happen at other RPMs I just can't hear it. It's also intermittent it like starts and stops sometimes correlating directly with high idling at idle but I'm not really sure as I haven't really done a scientific test. Any idea as to what this could be or where else I should check to get answers thanks.

sounds like someone is using a bench saw? best will be to pop the hood take off the plastic covers and lisen

could be the exhaust hitting something, or a heat shield hitting something while vibrating.

I found the culprit, does anybody know any next steps? I could remove it but it looks important.

The weld broke. Jobber fix is put a stainless hose clamp on it.

I did this, works like a charm so far. Hoping it holds. Didn't think it was worth getting out the welder and figuring it out my self. Thanks!
