what is the cause and problem of unusual sound in the motor?
i have this car Ford Titanium model 2008. i heard this unusual sound every time i start the engine. and if i press the clutch it disappears and as i go and shift to 1st gear and 2nd gear the unusual sound becomes louder. it sounds like a piece of bolt in a pot while you are shaking it. i just want to know what is the cause of it and how big is the problem. thank you.
