Just recently I've noticed a distinct exhaust leak "tick" coming from under the hood on the drivers side. I only hear it under acceleration, and it is quite loud because i can hear it over my loud exhaust. I have checked the manifold bolts and gasket-> good, down pipe flange-> good, and checked the manifold for cracks-> none to be found. So where the heck is it coming from???? please, any suggestions? 99 tahoe, L31 vortec.
