I recently noticed what sounded like a belt related noise coming from the timing cover on my 1997 850 T5. Touching the timing cover could increase or decrease the noise depending on where and how I touched it. I took off the timing cover and the noise stopped, but the belt was hanging about a quarter inch off the edge of the cam sprockets (away from the engine side), which explains the rubbing. That doesn't look good!
The car now has 193,000 miles on it and the belt was last replaced at 158,000 miles - but from the invoice it doesn't look like the tensioner was replaced. Neither was it replaced on the previous belt change at 108,000 miles. Does this seem like a tensioner problem?
Either way, will the cover prevent the belt from walking off the sprockets completely, or would it make more sense not to drive the car until I get this fixed?
Thanks
Rod
