Maybe thats why it is taking so long to clear it out. I had drained the system prior to removing the heat exchanger and was shocked at how much oilcoolant was still left in the engine.
This Is What Happens If You Put Oil In Car Antifreeze
Oil in radiator overflow. It will result in them becoming diluted which will prevent them from performing their function in the engine. Excess coolant is captured in the overflow tank so it wont leak. I do not remeber the cost of the part exactly. Sometimes a gasket or a crack could occur inside the oil cooler and it will cause the oil and coolant to mix up. If its not the cooler then it could be passages in the head which are allowing oil to tget in the coolant or head gasket concerns or damage in the block. While running oil pressure should exceed radiator pressure but when cooling down i am not so sure.
If oil got into the coolant because of an oil cooler leak there is a possibility that coolant got into the oil as well. This part is often much easier to replace and cheaper than a head gasket. Radiator if the cap thermostat and water pump are all fine the reservoir is overflowing most likely because of a radiator problem. On a lot of modern cars there is an oil cooler fitted on your car which is cooled by the coolant. Show full signature. Oil in coolant reservoir could be a minor leakage result or serious problem which could be checked in time if you take immediate action.
In older automobiles the radiator was made of copper and aluminum. Its also a very common problem so i recommend checking the oil cooler if you have one fitted to your vehicle. Have the service department do a full oil and filter change after they have put the new radiator in. It means there is something wrong. In more modern automobiles the radiator contains a lot of plastic. If you observe oil in the radiator reservoir tank its an abnormal case and you should check it out.
Since oil is lighter than water most of the oil in your cooling system will float to the top of your radiator or coolant overflow tank. These two fluids should never mix. If you see an oil slick floating on your coolant its important to clean out your cooling system to make sure your engine doesnt overheat. Draining the radiator just allows the oil in the overflow to drain down into it. Coolant and oil both are very much important for the engine. They should not be mixed.
This is often causing the coolant to pour into the oil pan instead of oil in the coolant system. Im beginning to think that if i just keep flushing it will eventually clear. Once it cools down and contracts the coolant is returned to the engine. Since it can become a more serious issue in the future we highly recommend you to have proper leak tests for the engine performed by a professional mechanic so that the car could avoid severe damages and extend its life.
