Can anybody help me out with this sound? I don’t think it’s a pulley. But I hope it is. I put a long screw driver on all the pulleys and I didn’t hear that sound coming through the screw driver. It sounds to me like it’s coming from the top of the engine. It’s got 120000 miles on it. Regular oil changes. It happens all the time whether it’s cold start or warmed up. It’s done it the entire time we have owned it which is 6 years. It hasn’t affected the driving at all. It’s just annoying. Any help would be greatly appreciated.
