I could see the acceleration of the cam against the valvetrain to cause a brief silence.
Especially when combined with a worn timing chain.
Or could it be the chain? Not likely to make a screech IMO.
Does the noise seem external and toward the front? I mean you started with the belt driven accessories.
Any access to inspect the flexplate and torque converter?
Noise SEEMS up front, but not positive. Seems more passenger's side and top half.
Not sure about access just yet.
I'm going to post some more videos. I think they could be very telling. I have my thoughts, but don't want to lead anyone.
