The noise is not there as you can tell in the first video. That was taken right after start up in about 45° weather. This was the first time it had started after the ecu was reset (hence the high idle). Also the exhaust manifold has several leaks which cause that generally gross but quiet ticking in the background

The second video was taken about 5 minutes after the first, and the noise had come back at that point. The engine was warm now and idle was closer to normal.

I listened all over the engine using a long extension, and could hear the best on the top of the middle of the head where I point in the second video. I listened to the injectors and they were perfectly normal. I took each of the spark plug wires out and the noise persisted (although slightly different as idle fluctuated). I also properly torqued the cam gears but it made no difference.

Also the compression was tested twice and it is fine. This rules out a bent valve or anything of the sort.
