The glow plugs stay hot for about 20 seconds after the car is started, it could just be the combustion- is it a mechanical knocking or just a louder engine knock sound?

it sounds more like a clunking rather than a knocking noise. the oil light seems to stay on a bit longer after all other lights on dashboard have gone out,
