Hello, My 05 Acura TL is making a ticking sound that sounds like valve tick, is that what it is? If so, is it worth fixing or will it not cause any harm? Below is the video of the sound, the engine is completely warm at the time of this video

 

Anyone?

 

I don’t hear anything in the video that’s especially concerning or abnormal. You might get a sound clip from the engine bay area and repost. Otherwise, I would just monitor to see if the noise gets worse.
