The repair strategy depends entirely on the source of the leak. Decoding the Emulsion: The Science Behind the Milk The transformation of oil into a milky substance is fundamentally an emulsion, where liquid coolant—composed of water and ethylene glycol—disperses within the oil.

However, when metal components fail, this process is disrupted. Alternatively, a cracked cylinder head or engine block can create the same hazardous mixture.
The most common physical cause is a blown head gasket, which creates a direct pathway for pressurized coolant to leak into the oil galleries rather than the combustion chamber. Surfaces must be machined flat to ensure a proper seal upon reinstallation.

If a head gasket is the issue, the technician will remove the cylinder head(s) to inspect for warping or cracking. Visual inspection of the oil filler cap often reveals a thick, brownish sludge known as "mayonnaise," which forms when steam condenses on the cooler metal surface.
