Default Weird Low End Knock/RodKnock?

At low rpm’s I get a metal clank that sounds almost like rodknock but I have no idea. It only comes when I’m blipping the throttle while I’m not moving (parked) and consistent at around 2-3k while driving. I don’t have a Accessport, but an open source tune so I can’t monitor knock detection or anything like that. Really worried about it.

Does it go away once the engine is up to full operating temp? I hear the timing belt tensioners are known to make noises that sound just like a rod knock. One thing you could do is at your next oil change, cut open the oil filter and look for bits of metal that got caught in the filter material. If it's clean, you're probably ok, or at least it probably isn't a bearing. If you find a bunch of metal flakes in there though, you might be looking at a bearing failure.

I was thinking tensioner too, and it doesnít really go away when itís fully warmed up maybe just less noticeable Itís hard to say.

Does the sound get worse with rpms? Is it only between 2-3k?

Does not get worse, only between 2-3k and it stays almost the same speed.
