White, Sweet-Smelling Exhaust Smoke: Combust pressure leaking into the cooling system can be burned in the cylinders, resulting in thick white smoke from the tailpipe that smells of antifreeze. The water contaminant strip the oil of its essential lubricity, allowing metal components to grind against one another.
Assessing Water and Oil Mixing Severity and Its Impact
When these barriers fail, the high pressure created by combustion forces its way into the cooling jacket or the oil galleries. How Water and Oil Mix: The Primary Culprits The integrity of the barriers separating coolant and oil is the only thing preventing these two fluids from mixing.
The crankshaft and connecting rod bearings are often the first to fail. This specific failure mode indicates a serious breach between the cooling system and the lubrication system, often pointing to a cracked cylinder head, a failed head gasket, or a compromised engine block.
Assessing Water and Oil Mixing Severity and Its Impact
Its role is to contain combustion pressure and seal the internal waterways and oil passages. Simultaneously, the water in the oil promotes rust and corrosion on cylinder walls and other critical surfaces.
