Regarding your noise I would check your air intake system,pay attention to split hoses,loose clips,intercooler etc,without hearing it, it is difficult to determine if it is a bearing noise but if the fan belt is removed then that would rule out various pulleys/alternator etc, your wet carpet-it would be worth looking in the engine compartment at the bulkhead and check there are no drains blocked with leaves/dirt etc,you could also remove the drivers door card and check the membrane is in place covering the door, if it is smelling of anti freeze then your heater radiator could be at fault also,just some things to check,good luck.
