2011 2LT V6 Loud ticking noise?

I have a loud ticking noise at idle coming from the passenger side on the engine. It's not a lifter, but I suspect it has something to do with the fuel injection. It has gotten really loud in the last few months and it's annoying but it doesn't seem to be affecting the engine performance. Any suggestions and should I be worried? Its a 2011 mid year car with 125k miles on the odometer.

if its a tick that is literally constant in timing at idle, its the High pressure fuel pump.

Yeah, that's it.. But it's getting louder? Is it getting ready to croak?

I've noticed the same sound as well. Mine got louder probably a year ago - haven't noticed any effect...yet.
