Sorry if this has been discussed to death as I know it's a common issue to an extent. Started the Mach today and got a loud ticking sound that is RPM dependent, coming loudest from the drivers side. It really isn't noticeable at idle but is quite loud and obnoxious under any kind of acceleration, light or heavy. I had a similar noise occur after I purchased the car and replaced the serpentine belt which stopped the noise all together. Now 3500 miles later the noise is back. Any ideas what it is or suggestions on fixes? Crossing my fingers the dreaded head tick isn't here to kill the Mach. Again sorry if this issue has been covered already. Thanks.
