This morning when I started my car. I noticed this sound. I tried to search on youtube but nothing is similar to this. I don't know what is the correct word for this type of noise. Is it ticking or chipping? The car is 2005 with 172000 miles. I have already changed the spark plugs around 165k. You can hear the noise more clearly if you use a phone to watch. TIA

Hello,

Hard to tell without knowing even an approximate area where the noise is coming from, but it frankly sounds like some heat shield that got loose and is now rattling away. Try to look under the hood to localize the noise, also try pushing on any heat shields that you see to see if those are the ones rattling, though just to make sure, they will be Hot.

Hope this helps and best of luck!

 

Thank you Arsenii. I think you didn't catch the noise I'm talking in the video. For some reason, the video I uploaded to youtube made the noise very hard to hear. This morning, I checked and I didn't hear anything. I will record it again if the noise come back
