I have a very well maintained/looked after Ford Escort 1.6L.
I've noticed that going from around 30 to 60 MPH there is a humming

seems fairly intermittent. It's not particularly loud. It's as loud as
the engine but a different tone, so you can hear it together with the
Any ideas what this might be. The Cars done 36'000 and was recently
serviced (Oil, fuel filter, plugs, oil filter) Belts were done 2 years
ago due to the age of it.
