Perhaps the most insidious effect is the emulsification caused by the mixing process. The block test is a simple chemical procedure where a special dye is added to the coolant reservoir.
Coolant Mixed Oil Water Pump Inspection and Diagnosis
If combustion gases are present, the dye changes color, providing clear evidence of a head gasket failure. Internally, the galleries for coolant and oil are designed to run adjacent to each other, relying on the integrity of the casting and the gaskets to remain isolated.
When this gasket blows between a coolant passage and a cylinder, high combustion pressure forces coolant directly into the oil galleries. An overheated engine is also a common symptom, as the coolant is lost and the engine temperature rises uncontrollably.

Symptoms and Diagnosis Recognizing the symptoms early can prevent total engine destruction. The pump's shaft seal or its mounting gasket can degrade and leak, allowing coolant to seep directly onto the block surface where it can mingle with oil residue.
