(mk1 Ford Focus 1.6 manual petrol)
When I'm reversing (only when pressing the 'gas') I can hear a metallic 'rolling/bearings'? sound of noise. Lift off, no noise. Press the pedal and its there again.
Cold start- from turnover for the first 5secs? The sound is also present- just briefly though.
I've also noticed recently that selecting 1st and reverse at standstill can occasionally be difficult. Clutch/clutch release bearing are recently replaced.
What could it be?
