Hello guys, was wondering if any of you guys driving 2.0AT Koup can compare the sound of your koup with my koup youtu.be/-t2DuO4n-6sMine is very noisy, you can hear the clack clack sound in the video, very annoying. The car is regularly service with fully synthetic oil 5w-40. I had tried using thicker oil 10w-40 but still sound the same. its been making this noise from day 1 up until now around 28k+km. I was wondering if it is the Valve Clearance that is needed to be adjust. Any mechanics in here who knows what this sound could be. I got a friend of mine with same engine but his engine sounds way quieter than mine. EDIT: Link to a thread on the Kia Forte Forum www.forteforums.com/forums/kia-forte-2-0l-engine-discussion/8497-koup-2-0-sx-engine-noise.html

bro, this is normal.
mine also same, and there is no way to adjust the tappet clearance at all due to is control by hydraulic from our engine oil.
There is 2 way to lower the noise, 1) is using a thicker engine oil 2) is using oil treatment
Now my engine sound is lower.
