What leads to the presence of engine oil within the coolant?

A malfunctioning head gasket can permit oil to escape into the cooling passages.

Ultimately making its way into the coolant system.

This outcome is responsible for the formation of the brown sludge visible at the radiator’s surface and within the coolant reservoir.

Conversely, coolant might also find its way into the combustion chamber.

What occurs if coolant infiltrates the engine?

Experiencing a blown head gasket can result in specific effects such as the emergence of white smoke and the appearance of milky oil, as previously mentioned.

Additionally, it has the potential to create pale deposits that will obstruct the spark plugs, potentially leading to further instances of engine power loss.

These indicators serve as valuable early warnings for identifying issues related to the head gasket.

How can you determine the presence of water in your engine oil?

While a significant portion of the water is typically expelled through the tailpipe, during periods of engine cool-down, a considerable amount might condense within the crankcase.

An uncomplicated method to identify water within used motor oil involves placing a drop of oil taken from the dipstick onto a heated exhaust manifold.

The presence of a crackling sound, reminiscent of sizzling bacon, serves as an indication of water contamination.

What prompts the mingling of water with oil within an engine?

The occurrence of a fractured or damaged head gasket can lead to the mixing of oil and coolant.

Additionally, if the engine experiences overheating, it can cause either the deterioration of the gasket or the formation of cracks in the cylinder head.

Thus resulting in the amalgamation of oil and coolant.

What color is oil if water gets in it?

However, should it become cloudy and acquire a texture akin to that of a chocolate milkshake, it’s advisable to have a skilled Subaru specialist examine your engine.

The presence of water contamination causes motor oil to adopt a milky brown appearance.

What is the safe duration for driving with milky oil?

Nevertheless, if the car has remained immobile for a prolonged time , the milky oil might be a result of engine condensation.

If you suspect this scenario, it’s recommended to embark on a highway drive lasting around 30 to 60 minutes.

This action will facilitate the evaporation of the accumulated moisture.
