so guys, really, i just want to see how many people can chime in and basically confirm just through the video im providing that what the noise i am hearing is a timing belt tensioner issue.

the sound is there on a dead cold start in the mornings. and its extremely loud as shown in the video. Im sure my valves make noise as well but this noise is very scary. after about 20 minutes the sound seems to go away and the car is decently quiet, but there is obviously something wrong.

i know i have been milking it for too long but honestly i couldn't justify spending over 1k for the 105k maintenance job. At this point i might just continue driving the car and seeing how long it lasts until the engine says bye bye. That or come to my senses and trade it in and get a lease.

Yes. This sounds like the tensioner. I would remove the covers for further inspection. I have an 05 AV6 and have replaced the tensioner around 97k while changing out the belts last year. It is not difficult to get to if you are willing to put in the time to replace it yourself.

Also, upon removal of the old tensioner I did noticed hydraulic fluid leakage and can only assume that what you are hearing is due to a shot tensioner.

Once the car warms up even a bearing that has no spinning parts left will work because it's formed a paste of old part to ride on, and is hot enough to do it.

The change isn't hard to DIY, and saves you many of hundreds of dollars.

Thanks for the info! Just can't really trust myself to do this job. I also have broken axles, warped rotors, and blown front shocks. So it'll be a major overhaul if i ever get to it , not to mention I don't have the skill set to do it

Take the serpentine belt off and turn on the engine to see if the same exists first. If not, the it's the tensioner for the serpentine belt.

You sure it's not the serpentine belt tensioner? But dang, that noise is loud. Any codes popping up? Is there any loss in power? I wonder if you have a bad converter or premature detonation. Also, try running higher octane gas. If it's just the tensioner, maybe it'll be a cheaper fix.
