my car started making a weird noise today (04 BA XR6T Auto - light boost increase) when I took off from the car wash.. gave it a bit as usual and cause the wheels were wet spun up the tires and revved the engine - which sounded much much louder than usual!?! at first I thought it was BOV sqealling and vibrating (the bosch valves make weird noises sometimes...) But the noise was a howling fine vibrating noise from the engine.. I tried to reproduce the noise after and it only starts to make it at 3,000rpm and above!! getting louder up-to redline!! I thought maybe loose exhaust heat shields but its far too loud for that! could it be timing chain tensioner, loose flex plate, engine mounts collapsed or MUCH WORSE :( Videos attached.. u can hear the tone of the engine change as it passes 3k, I only revved it to 4.5-5k in these videos (now freaking out its going to blow) can anyone make any suggestions?! or heard a noise like this before?? Ive looked it up everywhere and there are no other similar experiences :( Thanks Adric
