To me it sounds like a dry bearing and pulls /slow the engine down till a stall. This is the sound it made just prior to my valves bending and pushrods (see first fail). Odd enough, returning the next day the sound was gone and only a miss fire on Cylider 2 (the popping was seen on cylinder one in video)
Currently it is running on 4 cylinders and no noise. I have done several leak downs and compression test. Still in the Diagnostic phase of figuring what the heck is going on. Ever day its something different and new symptoms
Fuel pump is under the hood and 2-3 psi. It is relayed with the key on via the power relay on the play board. Self regulating at the pump

Is the howling noise the noise you re concerned about what we hear in the video BEFORE you turn the engine over and it sputters a little bit? The video you posted on the 12th?
@rfinegan If the key is in (I'm guessing it is as the head temps are reading) but the engine is off and something is howling, I'm thinking fuel pump. How is the fuel pressure at the engine?
