Dear all

I had encounter a problem with my forte recently. there is a gla gla gla sound when i accelerate my car in between 40km to 60km per hour. I cant pin point where does the sound came from and the sound is loud enough to hear in the cabin. Normally my car need to travel for 15 min only the sound will eventually came out. i suspect is from the engine.
Anybody encounter such issue? any recommendation on which service center to go and person to look for. Kinda need some advice here.

Thanks
