Ive got a 2011 chevy impala that just started making a ticking noise when your on the accelerator i dont hear it at idle. I assumed an exhaust leak so i took it to my buddy who has a car lift and looked underneath to find to no sign of a leak anywhere and honestly once it was up in the air the sound was gone, i even got in it on the lift and revved it and no sound. Soon as i pulled out the garage tho it was still there ticking away. Im at a loss im worried its my motor but it sounds like its coming from underneath the car not the engine. Any ideas?

Correct viscosity oil?

Correct oil level?

Oil not with excessive mileage on it?

Correct and high-quality oil filter?
i am overdue for an oil change but ive been right on top of it for the life of the car. Is there anything i should try adding to the oil to help clean it out like seafoam or something?
