The last video with the engine idling so nice. A bad rod bearing should have shown up even if faintly. As rpm increased, it sounded like something was out of balance or loose and start hitting something else.Oh really so you don’t think it’s rod bearing then? Did the second video not sound like rod knock or something,
Does it always start with the knocking noise every time with the belt installed? But with belt removed it doesn't knock at idle rpm?So I’ve just taken the belts off and started the car up, I normally have a rattle when I start the car but it didn’t do it this time, I believe that may be due to a rattle with the power steering pump when I move the the wheel cw and ccw it rattles.
It's too loud to call it rattling. What do you mean when moving the steering wheel and it knocks?
