My '06 Camry has had a jingling type rattle at idle for a while now
Especially noticeable at low speeds, drive thru, and with the A/C on
I had suspected it was a loose heat shield, but all seemed tight
There has been 3 different repairs of that exhaust section, because NYC RUST
Flex pipes welded twice, and the hanger reattached after I got rear ended in 2019
I thought it would be wise to take an internal look
So I removed the closest oxygen sensor, and worked my borescope into the system
This is what I found
At some point, an off cut of pipe, or welding slag broke off internally, and is rattling around against the intake of converter #3
Let's see some pictures
