My car has the faint dreadful puffing sound coming from the right side of the motor. I stuck my hand up around the exhaust and could feel air blowing in a steady stream. It wasn't hot air or coming out in a quick puff, puff, puff like I would think escaping exhaust gasses would be.
When there is a load on the motor when accelerating the exhaust note becomes very deep and loud. Like the sound of a Harley with open pipes. Once up to speed it gets really quite.
Am I doomed???
