What does the oil look like? Pristine and clear, blackened, glittery with metal chips, or what?

Re: Engine Sounds like rocks in a metal pan

I almost want to say it sounds like your catalytic converter is toast. They can sound like that when they go belly up and can choke the exhaust, which could possibly be the cause of the stalling. Is the sound definitely coming from the engine or under the car?
