Hey Forum-goers,
I had a guy come look to purchase my 2008 V6 Rav4 today and we discovered a new ticking noise. It seems to be coming from the back side of the engine, either the area of the exhaust manifold and such. It's definitely a centralized sound closer to the back right side of the engine when standing in front of the car.
Any ideas what this may be? As I accelerate it increases in the number of ticks per minute, almost as if it's following the RPM of the engine. 'hear' video for the sound, it's loud enough to notice with the hood open, not loud enough to hear in the vehicle.
Thanks in advance!

Update 06/30
I went to the underside of the car, it's significantly louder from under, see this video.
Also, at cold start I could barely hear it and it got louder with the engine warming up, see this video.

It could be a fuel injector ticking. They all tick, but maybe one is going bad?
