I'd noticed recently my car sounded rather ticky as I accelerated. At first I thought nothing of it attributed it to my imagination. Though yesterday it was much louder (after an autox no less) and so today I decided to check it out. I had my girlfriend push the gas as I stuck my head in the engine bay. The sound is eminating from the front of the engine, and the discintct smell of exhaust is present as well. Im very happy that its an exhaust leak, I was afraid it was something worse!
