As sallam Alikum Everyone,

An expert opinion is needed regarding the problem in my Toyota Corolla 1.6 2015.

I am facing the issue of HISSLING SOUND on my corolla on acceleration.

(The sound is not similiar to Grinding sound its like some whistle, like any air leakage type)

I have already changed the Timing Chain, Timing Chain Adjuster, even checked the sound after removing the belt.
But the sound is still there.

I have consulted with many mechanics but NO SOLUTION.

Try changing the generator belt.

Brother, I have same problem with my GLI 2010. A week before I have traveled for approx 5000km up to northern areas but noise is still there, I have checked many things like timing chain, tetioner, vvti, accelerator pedal but still can't diagnose the problem. so at last I am just thinking to change the throttle body maybe this noise is from throttle body, but not sure....
