Just installed Air Pump drive belt on my 308 and it is very noisey. Are these pumps known to be noisey? Thx md
TAKE IT OFF NOW!!! You don't need it to run, If the brg seezes up you'll skip the timing belts and TRASH your engine!!! NO they are not supposed to make noise. DO THIS NOW!!!
When you remove the air pump, do you have to re-tune the car..(1980 400i ..Florida no smog required)..I know that I'm not in the v12 forum..but" inquiring minds must know"..thanks in advance..Jacques..
