I have a 1967 Mustang with a 200 ci six with auto trans. I have owned it for 4 years and when checking this year I notices a white film on top of anti-freeze in the radiator. Changed hoses and flushed system. After driving around for a few miles, checked and white film present again. I believe I have oil getting into the coolant. What is the most common cause. Hoping it's just a head gasket.
Thanks,
Bud
