2013 LFX Camaro 2LT with 53k on it

Feedback is appreciated:

I don't know if it the motor is supposed to be as noisy as it is but
its almost like clicking/fluttering under the hood.

Cant hear it inside nor is there loss of performance. No CEL

-new airfilter
-cleaned throttle body (didn't look like its been cleaned before)
-seafoam through brake booster

Is it possible oil/carbon build up due to lack of catch can ?
