Hi folks!

Got a quick question.
I know that cam gears make that whiny noise. It was very subtle when I first got the car. Now at 6000km the noise is much more pronounced to the point that this is the only thing I can hear driving in first few gears at lower RPM's.
At highway speeds no issue.

I am wondering whether it's normal for this noise to get louder over time (break-in). Are there any factors affecting it, such as outside temperature, etc?
