Why is there oil in my coolant but no coolant in my oil?
The reason no coolant is in the oil is because it is a high pressure leak, oil pressure is always higher than coolant pressure when running, so if the leak only happens at 20-25psi or above, coolant will never get into the oil. Other than that it could be a head gasket as suggested but is rare.
How to tell if there is oil in coolant?

Why does my oil heat exchanger mix up?
Sometimes a gasket or a crack could occur inside the oil heat exchanger and it will cause the oil and coolant to mix up. This part is often much easier to replace and cheaper than a head gasket. It’s also a very common problem, so I recommend checking the oil heat exchanger if you have one fitted to your vehicle.
Why does the head gasket blow up?
The gasket ensures that the combustion’s air pressure doesn’t light-up, and the oil that’s in the engine doesn’t leak out. If an engine overheats and stays heated up for prolonged periods without cooling, the head gasket blows up, causing the oil to leak into the coolant system. This is why some oil may be getting into the coolant reservoir.
How to check for leaks in engine oil?

Signs And Symptoms Of Coolant In Oil
Engine oil mixing with coolant signifies a blown head gasket or an engine breakdown. It affects your oil’s lubricating and viscosity properties, leading to a decrease of lubrication and engine power, and can lead to engine damage. Below are a few signs to determine the presence of coolant in your oil.
How To Fix
According to the nature of the problem, you may either DIY it or get an expert’s assistance. The culprit might be an overheated engine, a leaking head gasket, or a clogged oil cooler. The most frequent cause is a leaking head gasket.
Cost
Numerous variables can influence the overall cost of this issue. For instance, if you need to repair the transmission cooler, you will need to change the radiator and conduct a transmission servicing. This task alone can cost from $350.00 up to $450.00.
