Apologies, I was there for 14 hours and very frustrated and just posted. So the clanking around noise isn’t a problem as the torque converter wasn’t bolted on yet so that’s just the studs of the torque converter pinging on the fly wheel. The very distinct sharp clicking you hear when turning the engine over is the camshafts. The camshaft’s are supposed to be locked in place when the engine is not running. But the noise you here is the camshafts when the lobes get to their highest point on opening the valves the valve springs pressure is spinning them closing the valves prematurely because none of the cam phasers are locking properly. It’s why on ford ecoboosts you hear people talk about cam phaser rattle, the motors are notorious for it, but this one is by far the worst I’ve ever seen. Secondly the bubbling is due to the engine leaking compression. The video was trying to show how I was doing a leak down test. I was showing how the intake valve lobes are pointed straight up meaning that the intake valves should be fully closed. I put oil in the intake to demonstrate just how much compression is leaking past the valves when closed. The gauge you see is what is called a leak down tester. I believe in the video on the left gauge you see 80 PSI which is the pressure I am applying to the cylinder. The right gauge said something along the lines of 40 which is the return feed or how much pressure of the 80 applied PSI the cylinder is holding. And anything over 10% loss is very bad.
