LupoLooney88

Hey People! Im a newbie here so just wondering if any1 has some advice! Just bought my first lupo yesterday...pretty bog standrd 1l E. When we were out for a drive last night there was like a running or trickling water noise when accelerating. It seemed to stop when the clutch was down or foot off the gas pedal?? Spoke to a friend who said he'd only ever heard that noise in a Saxo after the head gasket had gone!! Oh no!! Hope someone can help! Thankx Jaye xXx
