I am losing coolant after I drive and park the car when it cools and the engine oil looks like coolant getting in it, but there is no oil in my coolant. I have to keep adding coolant like maybe 10oz a day. I changed my hoses and it is still the same.

Hello,

Any time you have coolant mixing with the engine oil, this is usually a sign of a blown head gasket. In rarer cases it can also be a cracked water jacket introducing coolant into the engine oil that way, but 9 times out of 10 it's a blown head gasket. There are a couple of different ways to confirm that your head gasket is blown and I have included links to both of them below.

Please go through these guides and get back to us with what you find out. We can go from there.

Thanks,
