I just bought a 2013 X5 with 17k miles. The motor sounds like a pulley or belt is whining when cold. The dealer told me the sound was normal and was from the valvetrain.

Is the sound normal for the 4.4L engines?

I did research recalls by VIN prior to purchase and no engine issues listed.

Although I did see issues onlibe prior to buying they were mostly pre-2013. At least the ones I found.

I have the N63B44O1 440hp and can't seem to find many issues online for this motor. I am just concerned with the noise the dealer claims is valvetrain noise and is normal. Only does it cold.

This is what the engine looks like ...

It's one of those moving parts external to the engine:



If it is an internal part, you can use this picture:
