Mrb friends good feasts, first of all, when I press the gas while cruising or idle in my 307 xr vehicle, the vehicle makes a ticking ticking sound when the vehicle exceeds 2000 rpm, but this sound comes from the engine, not from the plastic parts. The issue is when I am driving on the highway, I pull my foot off the throttle, I press the throttle or I get it idle, there is no sound, but when I put it back into gear and press the accelerator, the same noise continues. When I listen to the sound, the suction is coming from the monifold. Do you think valve tappets?
