Default 04 WRX Engine Noise need help!!!

Check out this video:

Its a 2004 Subaru Impreza WRX 2.0L - Does anyone know what this ticking or knock could be? I think it could be something with the valves but I have no idea. Going to do a compression test and take the oil pan off to see what I can find and check the oil for shavings. Any other ideas on what I can check myself? It doesn't overheat and when it idles sometimes the ticking isn't near as loud. Hoping its not a problem with the pistons or engine block.

I would be surprised if that was anything other than rod knock. Maybe a destroyed valve of some sort?

Yep it is a dead bearing. It was/is a common issue with the 2.0L. Sorry to hear that.

It can also be an idler or timing belt tensioner. Take off your timing belt cover to see if it gets louder or if you can see anything.
