How do I know if my 6.0 oil cooler is bad?

Trouble is, oil cooler failure is very hard to detect unless you're viewing the engine's oil temp and coolant temp in real-time as you drive. A temperature difference of 15 degrees or more between the two parameters usually means the oil cooler is in the early to moderate phase of plugging.

What does brown sludge in coolant mean?

Corrosion – this is the most common cause of sludge build-up in a radiator. Radiators, like most parts in your engine, are made of metal. Over time, antifreeze can degrade. As it degrades, coolant loses its protective qualities, PH levels change, and corrosion sets in.

The reason no coolant is in the oil is because it is a high pressure leak, oil pressure is always higher than coolant pressure when running, so if the leak only happens at 20-25psi or above, coolant will never get into the oil. Other than that it could be a head gasket as suggested but is rare.
