I have developed an oil leak and it appears to be coming from the timing belt cover. I had a local shop look at it and they claim it is a seal that is behind the timing belt housing. What could be leaking from there? Since I have ~75,000 miles on the car, I was thinking of replacing the belt also. Shop wants ~$350.00 to do the job, around six hours. Does this sound plausible?
Thanks for any advice you can give me. Dan
