Why would car make a load banging noise loose oil pressure stall and leak out milky oil?
The milky oil is because there is coolant mixed in with it. This happens because a gasket inside the engine failed. That being said, oil is an awesome lubricant. Oil mixed with coolant is not. The engine effectively chewed itself to pieces because it was not properly lubricated. The loud banging you’re hearing is because the lack of lubrication caused a spun bearing ( a VERY bad thing), and the loss of oil pressure is either because the oil pump died, or because all the oil is now gushing out where that bearing used to be and not lubricating anything else. What i’m trying to tell you is that you need a new engine, yours probably cannot be saved.
