Terrible engine noise cold startup
So this seems worse than lifters and Ive been noticing it's getting worse lately. I really don't think it's bottom end noise because it's been doing it for a couple months now and it hasn't took a **** yet. Runs and drives fine other than this noise. Could it be timing belt pulley or tensioner? Sounds like it's coming from right behind the cover but I can't be certain. Noise goes away once it's up to normal temp. I'll drive it around the block after dinner and take another clip to show how it sounds after.

Have the car up in the air and nothing obvious. There aren't any shields or braces on my artech exhaust so that's out of the question. Also disconnected the alt/wp belt and no change in the noise so it's definitely engine related. I drove it into work and took it to lunch and again, the noise subsided each time the car got up to temp. I guess next step will be popping the valve cover and timing cover off and see if anything looks loose/broken in there. Won't have time today so I'll have to get to that this weekend. I was supposed to bring the car to be tuned this week too ... Blah

Yes I can definitely rest easy now knowing it's a simple fix and I will still be able to get it on the dyno next week. I'm anxious to swap the pulleys out and start it up and see if it's quiet lol
