That happened to me too. My engine had been rebuilt and then I drove for about a month and then I checked the oil level and there was no reading. I later found out that the oil control ring was not resting on the cylinder wall and was letting oil go inside the crankcase. The end result: oil burning and coming out the tailpipe as blue exhaust. You should have a leak down and block test performed on the engine to see if your internal parts are worn.
