The pressure from the combustion events pushes these fluids past the seal, resulting in the emulsification observed on the dipstick and the leakage that forms puddles under the car. You might notice the engine running roughly or misfiring due to combustion pressure leaking into the cooling system, which disrupts the flow and creates pressure bubbles.
White, sweet-smelling smoke may also emit from the exhaust as coolant burns in the combustion chamber. This specific symptom is not merely an inconvenience; it is a critical diagnostic clue pointing to a breach that allows coolant to mix with the lubrication system.
