A friend tested my radiator pressure with a pump, and now my oil looks like chocolate milk. What made this happen? And how can this be repaired? Is the engine shot, or can I change the oil?

it sounds like you had an overheating issue and you blew a head gasket.

The oil would turn chocolate or milky if coolant is mixed with it. This is a fault of a bad head gasket.
