Thanks for asking your question. I will try and help you out.
Most often oil in the radiator is caused by a failed oil cooler. However when it's not. There are two other things that can cause this.The first is a cracked head. It's rare but I see it from time to time.Second is a hole in the liner. This is very rare and when it does happen, only a small amount of oil enters the cooling system. To verify, I like to drop the oil pan and pressurize the cooling system. If a liner has a hole. Coolant will enter the cylinder.Please reply back if you need more help or have more questions. I am happy to assist.
