When I am driving by something that reflects sound and I accelerate I hear a ticking sound. At idle or revving engine in park the sound can't be heard. But is very distinct when passing walls etc. and accelerate. Reminds me of the sound I had in another car that I had when a spark plug socket was leaking. Would it be possible to get this sound from a leaking exhaust gasket? Does not sound like a lifter or valve as I would think I could here that at idle or revving in park. Any ideas?? Been doing it since I had it so don't think it is anything major and not getting any engine codes from it.
