I have oil in the coolant but not coolant in the oil. There are no leaking oils and I have been driving the car for 20,000 km with this problem. The car does not overheat. Although I have to drain the coolant every 4,000 km or so as the oil will be bad. Please help.

Hello, I am Danny.

It sounds like you are having an issue with the oil cooler inlet or outlet leaking into the housing(s) through a gasket/leak/or possible crack. I have attached pictures of where they are located (circled in red)on the engine. Hope this helps and feel free to ask any further questions if needed. Thanks for using 2CarPros.

Good morning.

The most common issue for this condition is the oil cooler. It leaks internally and ends up in the coolant.
