Oil in Antifreeze
courtesy of Bob, The Auto Answer Man
The radiator in my auto has what appears to be oil in it. after twice flushing it came for the most part clean. there still appears to be a sludge forming. the logical conclusion would be oil. but having kept a watchful eye on the oil it has not moved. what should I check and/or watch for?
Oil in the antifreeze can only mean one thing, bad head gasket. There are several things that can happen when a head gasket goes bad, one is oil leakage into the antifreeze. Other than a crack in the block, there really is no way to get engine oil in your coolant. Well, no, there is another way, but would depend on whether or not you have an oil cooler built into your radiator. Are you sure it is engine oil? or is it just an oily substance? But in most cases, this is a sign of a bad head gasket.
