Hemi tick?

so I noticed this annoyng racket coming from the engine while I'm driving near a wall, other cars or a divider. It gets louder when MDS is on and becomes faint again when all cylinders fire up. i tried parking and revving the motor up but heard absolutely nothing at all. Is this the infamous Hemi tick?
Thanks.

I know the noise you're talking about... I have it too and it is the "hemi tick".

At first i thought it was a faint exhaust leak and went crazy looking for the source :rofl:

My 2007 doesnt have an MDS indicator so i cant tell if its worse or not when MDS is activated.

Really??? I was sure I have an exhaust leak. That sound is normal for the hemi?


:eek:rangehat:

I hear my tick at all speeds (windows down and radio off!) from moving from a standstill through highway speeds. In my case, I don't think it has anything to do with the MDS.
