hey guys i have discovered a rattling noise not sure where exactly its coming from but its pretty audiable, my first thought was a big end bearing (i hope not!)
it only happens on deceleration between 3500rpm and 4500rpm. cant hear it on idle light acceleration or full throttle so its not there on any kind acceleration, its not a constant type rattle its more of a sound like metallic objects hitting sheet metal but in an almost ready to take out of the microwave popcorn like fashion if you get what i mean lol ive read it may be the catalytic converter but i am unsure if the alfa 33's came with one from factory? can anyone confirm this? as i really cant afford it to be a big end bearing! the car has 220,000km's on it so im suspecting if it does have a cat that may be the problem. but if it isnt that or a nig end bearing could it be something to do with the tensioner pulley or a loose heat shield etc?
cheers guys
