What does it mean when you have oil in your coolant?
The most common cause of oil in the coolant reservoir is due to a blown head gasket or a cracked oil/coolant heat exchanger. It can also be caused by a faulty transmission cooler. In rare cases, it happens because of cracks in the engine.
Why is there oil in my coolant but no coolant in 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.
How do I get rid of oil in my coolant system?

Will a car start with a cracked head?
Yes, the vehicle will start with a blown head gasket, but its health conditions are at risk. As pointed earlier, the work of the head gasket is to provide a seal between the cylinder head and block of the engine. The seal is enhanced by preventing internal combustion gases from mixing with the oil.
How long will a car last with a blown head gasket?
