Engine/transmission Sound question
I have an odd question: one of those strange sounds questions. Ď14 F30 with 115,000 miles. The car, while under load (throttle), is loud. The noise seems to come from the front right of the engine bay (based on sitting in the driver seat, driving the car). The noise sounds like a muffler with a hole in it, or one or those fart box mufflers. Except itís not quite loud. Sort of like an over revving engine, but my RPMs seem normal.
I was wondering if it could be an exhaust leak? Praying it doesnít have anything to do with the turbocharger. I havenít experienced any drop in MPGs or performance.
The noise only occurs when Iím on the accelerator, even maintaining speed. It quiets/slows down when I let off the gas and the car slows.

If it is just engine noise you probably have an exhaust manifold or header crack.
If you do have a turbo issue, and it was making a noise, it would make one hell of a friction sound that would not sound like an engine and be a much higher rpm. But you could take that off, ship it to a turbo re-manufacturer, and reinstall for under a grand.
Dealership diagnosed it as a wheel bearing. Weíll see.
