High pitch noise

Shamza · 10-09-2016, 10:02 AM

Can anyone identify this noise? It's very high frequency, very apparent at 700rpm.

It's not a pulley or belt. Could it be timing chain related?

Vaccum pump maybe?

Isn't that in the wheel arch?

I might be going deaf, but I couldn't hear high pitched noise. Sounds perfectly normal to me.
