Is it leaving a puddle on the ground after sitting overnight? If so you could have a major leak, it could be anything from a stripped oil drain bolt and a bad oil pan gasket ect. You will most likely have to try to track the leak down yourself, you may also need to degrease the motor to find the leak.

no its draining back into the oil pan so when i crank the car up it sounds like its dry and no oil pressure or compresion then after a couple of cranks it will start and run fine the rest of the day . the motor was rebuilt two months ago.im pull my hair out. lol...
