Hello,

It sounds like you have a blown head gasket. The milky substance is a sign of coolant mixed with oil due to a failed head gasket.

In order to replace the head gasket, the cylinder head needs to be removed. Also, it is recommended to check the cylinder head and the block for any warpage while it is apart.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
