Okay, I have a Mazda CX-9 2010 I have replaced the thermostat and the crankshaft sensor. It's blown out white smoke and it's got creamy tan oil now, like water or something's getting in with the oil but it's not the head gasket yet. That's been shaped but they're saying it could be something's getting in my oil making it mess up and I can't drive it. It's not getting enough gas or something but it's messing up my engine and I cannot afford $4,000 and I called today and that's what's going to cost me. And I need my vehicle for school and work. Please help please.
