Hey everyone (I posted this on the 12 cylinder part of the site, but I do not know if you guys look there ... and, truth be told, you have provided me with some great info in the past) ... so, if anyone knows the answer on this one ... I own a 456 and started it up this morning. I heard some belt noise, and smelled the buring of rubber (I just had a major service this year, 1000 miles ago). I quickly turned off the car (it seemed like both banks of cylinders were running, but not sure because I shut it down very quickly). When I looked under the car, there were belt fragments on the ground, clearly melted ... I think they came out of the "front" belt casing - there is an opening in the bottom (if I am not mistaken, this is not the major cam belt, correct?) So, what could have caused this? Could it be the cam belt? Is my alternator/AC unit, etc., probably seized? Can I start the car to get it on a transport? You all have been very helpful here and I REALLY APPRECIATE IT!!
