I have an odd problem, where my engine sounds like it has a warped sound when running. At idol, it sounds like when something is off center anh has a kind of a "wha wha wha" sound. I thought it was initially a warped fan, but further inspection puts the sound farther back. A BMW mechanic said he thought it could be a tensioner bearing and would take a look at it, but estimated 450 for the tensioner and the belt. I would replace that but the sound seems to be coming more from the mid to rear of the engine. I have fair mechanical knowledge and have never herd a sound like this. It isn't something like a valve tick, and motor only has 71K on it. I ahve had the car for 11k miles and it has always had the sound. I know it is hard to diagnose without seeing the vehicle, but any help would be great!
have the same problem?
