Odd noises when accelerating?

Hello,

I have a mysterious issue that has been plaguing me for the past 2 months whenever accelerating from a stop I hear a clicking sound but only when I give light gas, also when giving my car full throttle I can hear a repetitive squeak like sound with a metallic tone to it. All the mentioned noises do not happen when stationary and revving the engine etc, I have changed the upper control arms and the brakes and PCV valve until now and am getting desprate.

Thank you for your help!
