i just bought a 94 mustang v6. It is currently not running. the problem is that when turning over the engine, water starts to come out of the exhaust. also when i checked the oil level, the oil was like brown mud and was past the full mark by 3 inches. I drained the oil and it seems that there was more than double the normal level of oil there should be. It was very thick and brown. would that because of water getting into the oil? There was also no thermostat in the engine, would that cause the problem? any ideas on what the problem could be would be very helpful
