Here's the thing though. It doesn't sound like it is coming from under the hood. It is more prevelant under the car. I'm leaning towards an exhaust leak, but I can't trace it. I really don't want to go through an engine replacement. That is why I got rid of my Infiniti G35 Coupe in the first place and ended up with this car.

Also, it isn't a faint tick, it's very noticeable, especially when next to a wall.
