I have oil coming into my coolant bottle for a while. got a new engine and the same thing is happening. what might be the cause of this?
I have replaced the radiator. I have to get it flushed out every 2-3 weeks depending on
how much I drive it.
leaky head gaskets or cracked engine block
My best guess would be something relating to the head gasket.
the answer to that change your oil cooler boss its the cause
a cooler unit under the radiator which cools transmission oil
