    Oil light works when pressure is very low....would have to be virtualy no oil in pan for it to come on.

    Some vehicles do have a low oil level warning light on the dash but I do not think yours is one of them. If the engine emits bluish smoke from the exhaust on cold start, the most likely cause would be either worn exhaust valve guides or dried up valve stem seals in the cylinder head. When an engine is shut off, oil that is pumped to the valve train can remain in the top of the head for a short time before draining to the pan. This is when some of the oil can leak down past the seal, between the valve and guide and into the cylinder. When you start the engine, the oil that leaked into the cylinder will burn with the fuel and cause the smoking.
