Hello again. A longer time ago I noticed a strange noise comming out from the engine area. It was after a longer (10 - 15km) drive when the engine was warm already. I parked my car and when the engine is just running a hear strange lets say knocking sound in the backround when I am inside.
I can hear this sound also from outside. Service guys are saying everithing is ok and they do not hear nothing...but it appears only after a little bit longer ride. rpms are still, a have no problems with the acceleration or something else...just this stange noise.
I decided to make a video so you can maybe give me some advcce what can it be, if its normal or what. you can see it on this link

I embedded the video for you.
Which noise are you concerned about? I hear a rumbling noise and a ticking noise. The ticking noise is normal as it's the sound of the fuel injectors. The rumbling noise sounds unusual and my guess is that one of your pulleys driven by the serpentine belt has worn bearings. However, the nature of the rumbling noise is hard to tell from just a recording. The ticking noise is normal so don't be concerned. My Kizashi, as with my other cars, have made that noise.
Did you know there is something called a sound camera that was specifically designed for pin pointing rattles in cars, albeit it is now used for other things. I just sore it on the telly and thought you may want to know
