Long time lurker, who fixed many a problem with the information on here. Sadly, can't find anything that fits the bill for this. So hoping anyone of you might make an educated guess.
The sound is there only from around ~1000-1100 rpm.Can't exactly locate it but what is filmed seems to be the general area. Not sure if it's a belt noise. Seems to chug a bit and isn't that constant. Belts look okay, sprayed them down to no effect. In hindsight not have been able to reach the ones down in the engine bay properly. If I can say for sure it isn't a belt will try to locate the sound with an automotive stethoscope. In the mean time, someone here might exactly know what it is and prevent me from going on this wild goose chase.
