In cases like this, a sound clip (or video) is absolutely needed, to be able to know what the OP is talking about. I'm convinced it's not piston slap, since if it was, it'd be MUCH worse when cold. Without hearing it, no idea what could be. Another VERY important detail is if the noise wasn't there before, which clearly indicates some kind of (changing) issue. My engine sounds really healthy cold or hot, fortunately... except a very annoying rattle that I immediately knew what it was because my truck developed it, and just fixed it by changing the PCV valve. Selling dealer (out of town) didn't have one, so I just ordered it along with a bunch of crap. It should be quiet after replacing it. Right now it makes the noises any such engine makes, and it's actually on the quiet side, so happy with that... but only 200+ miles on the clock now. No engine is going to be silent, and that's why I was curious to hear the OP's.
