This symptom is too often mis-diagnosed as a bad head gasket with unneeded repairs performed. There are many other things that can also cause this and it is rarely a headgasket.

Why does my car oil look milky?
If you do see milky, tan-colored oil collecting on the dipstick, in the oil cap or elsewhere in the engine, bring it to our service center. The most common cause of this is a coolant leak somewhere in the engine causing coolant to mix with the oil.
Why is my oil tan under my oil cap?
We have a lot of rain and plenty of humidity here in the Seattle area. Sometimes, like if you have a short commute, condensation that collects in the engine while the car sits overnight won't completely burn off. As the water vapor remaining in the system rises , it'll collect under the oil cap and mix with that oil. If that's the case, it's a good idea to take your vehicle on a longer drive once in a while, so it gets all the way up to operating temperature. The bad news? If it's not condensation, then it's coolant intruding on the engine oil. That indicates a major leak, such as a blown head gasket, which should be addressed right away for safe operation of the engine. Trust the pros at Carter Subaru Ballard to diagnose and fix this issue correctly!
Does condensation burn off oil?
Sometimes, like if you have a short commute, condensation that collects in the engine while the car sits overnight won't completely burn off. As the water vapor remaining in the system rises, it'll collect under the oil cap and mix with that oil.
Why does oil turn milky white?
Oil turning milky white generally means that water is entering the reservoir. This water can come from rainfall or if the hydraulic unit is washed down by personnel. Failure of a water-cooled heat exchanger can also introduce water.
What temperature does hydraulic oil freeze?
With Gear oil and Hydraulic oil it's freezing temperature is set for –10°F. And, same as motor oil, it becomes less viscous the colder it gets. However there are certain oils that do work below freezing temperature and those are generally the thicker kind of Motor Oil's like 15W30, which freezes at -55°F.
What causes hydraulic failure?
Fluid Contamination. Fluid contamination is often the primary cause of hydraulic failures, as it speeds up the rate of wear and tear on the pump.
Is water heavier than hydraulic oil?
Similarly, is water heavier than hydraulic oil? Gravity separation Zoller said that because water generally has a higher specific gravity than hydraulic fluid (exceptions do exist e. g. HFD-R), it tends to settle at the bottom of the reservoir when given sufficient resident time in a still environment.
Is hydraulic oil a fire hazard?
09 April 2013 Hydraulic oils are not generally considered a serious fire hazard, because they have high ignition temperatures. On factory premises, such a conflagration will unavoidably reach cables or other combustible material, which will catch fire and be rapidly destroyed.
Is hydraulic oil the same as hydraulic fluid?
Hydraulic oil and hydraulic fluid are terms that are sometimes used interchangeably, but they are not necessarily the same. While hydraulic oil is a fluid, hydraulic fluid can also consist of other fluids, including plain water, water-oil emulsions and salt solutions.

Why does my car have milky sludge?
At our auto repair shop, we typically see this due to condensation in the engine. This happens more often during weather changes and we also see it in cars where clients don't drive it a lot. Driving short trips doesn't allow the engine enough time to burn off the water vapours. Over time, this milky sludge builds up and accumulates. Your technician may suggest running a chemical through the engine to clean out this sludge, and you can help by driving the car for a longer duration.
Why does milky oil hurt?
You might have a very tight hamstring in your leg that torques on your pelvis and causes pain in between your shoulder blades from the compensation.
Why does my oil pump make milky?
A stuck or missing thermostat will cause condensation to occur inside your cylinder walls due to the constant extremes of heat from the engine and cold water from the water pump. The condensed water will work its way passed the piston rings and into your oil which will make it milky.
Why do cylinders get cold?
You’ve got hot cylinders internally, and a very cold environment around them causing the cylinder walls to become cold despite the combustion internally. The extreme difference in temperature causes condensation from any moisture in the air to form on the inside of the cylinder walls like you would find if you brought a cold can of beer out of the fridge on a 90-degree day.
Why does my outboard have milky oil?
An outboard will have milky oil most commonly due to the thermostat being stuck open or being missing altogether. After the thermostat is ruled out, the cylinder walls might be scored, the piston rings damaged, or the head gasket is blown. That’s the quick and easy answer for you.
Why does the thermostat in my engine only exit the hole?
It is supposed to only exit that hole at first because the thermostat in your engine is actually trapping the majority of the water and the pump is simply keeping the pressure. The water is kept trapped in the galleries and water jackets around your cylinders until they get up to running temperatures.
How does trapped water heat up?
The trapped water is supposed to heat up by cooling the engine as it warms up. When the temperature gets to a predetermined temp on the thermostat, the thermostat will open and allow hot water to flow out through your exhaust and allow new water in to help cool the engine and keep it at the ideal temperature for combustion.
What happens when a piston drives up?
Conversely, when the piston drives up, it will expel exhaust through the hole in the gasket and into the cooling water jackets. This sudden influx of hot gas into the cooling water will cause the water coming out of your indicator to start to stream erratically as air is being blown back through the line.
