my Ford Focus is from 1999 and was well kept and regularly serviced. That is until I got my hands on it! For the last 4 or 5 years it hasn't had much in the way of servicing just the odd oil check, and mot service etc... and I expect I'm going to have to go to a garage and spend lots sorting things out. But before I go I'd like to at least have some idea of what the problem(s) might be.
Over the last year or so the engine has started making a whirring noise. The noise is more pronounced when the engine is cold and although it isn't as bad when it heats up it never goes away. If my foot is on the clutch the noise goes away a bit.
The noise is pretty loud and I've heard other cars sounding like this.
The oil was very low and I've only recently filled it up. Although I guess the oil might have something to do with the problem, filling up didn't help much.
What is the likely problem? Thanks in advance for suggestions
