The oil light may be on due to low oil pressure not oil level. Could also be the cause for the noise at start up. If there is excessive bearing clearance. Also oil pressure is at its lowest at idle which would explain the light staying on at a stop.

So is that major your talking about ??


It could be yes....it could also be something as simple as a sensor that is bad and the noise isn't even related for all I know without hearing the noise. If it is oil pressure it means that the engine is failing and wont probably last long. That would honestly be my best guess by your explanation I'm sorry to say.
