How To Get Water Out Of Engine Oil

Are you facing trouble starting your car? Try to reminisce about what did you do for the last time. If you left your car in idling condition for an extended period of time, there’s a good chance that the oil has become waterlogged.

If you notice water droplets coming out of your engine every time you turn the key, it’s time to get the water out. However, the problem of getting water out of engine oil has long been a challenge for mechanics.

So, you might be wondering how to get water out of engine oil. Don’t worry, we’re here for you. No matter how tough the situation is, we have gathered some of the best methods for getting water out of engine oil.

How does water get into motor oil?

Motor oil is the lifeblood of an engine. It lubricates the parts, prevents corrosion, and helps to keep the engine clean. So, when water gets into the engine oil, it interferes usual activities of the oil and creates several problems. But, do you know how does water get in your engine?

Well, there are several things responsible for getting water into engine oil. One way is through the air intake system. The air that an engine breathes in contains a lot of moisture, and some of it inevitably ends up in the oil.

Another source of water is condensation. When you put the oil cap on, moisture can condense out of the air and into the oil. And if you leave the cap off for any length of time, that moisture will begin to evaporate. This can also be a problem.

The third way that water can get in is by the oil itself. The oil lubricates the engine and carries away heat. As the oil heats, it expands, and this causes a pressure drop in the crankcase. The pressure drop causes water to enter the crankcase through tiny cracks in the oil.

What Happens If Water Gets into Engine Oil?

If water gets into the engine oil, it can cause a number of serious problems. First up, the water can dilute the oil, making it less effective at lubricating the engine.

The water can also cause corrosion and rusting on the internal parts of the engine. Finally, the presence of water in the oil can create a sludge that can clog up the engine’s filters and valves.

All of these problems can lead to decreased performance, increased wear and tear on the engine, and even complete failure of the engine. The problem with water in engine oil is that it has a very low boiling point.

As a result, it will quickly evaporate into steam and be lost as a part of the cooling system. If the problem persists for too long, its impact will not go away even after the water is gone.

Water in Engine Oil Symptoms

If you’re experiencing any of the following symptoms, it could mean that there is water in your engine oil:

How to Get Water Out of Engine Oil

The water content in the engine oil is not harmful in small amounts, but it can cause big problems if it accumulates. Water can lead to corrosion and wear on the engine, and it can also cause the oil to break down prematurely. So, if you have already realized your car’s engine oil has water and causing issues, it’s time to take proper steps. Here we go:
Mechanical Method

Step-1: Get the car up in the air

If you’re experiencing water in your engine oil, the first step is to get the car up in the air. This will enable you to access the drain plug and remove the oil. Make sure you have a container ready to catch the oil as it drains out.

Step-2: Jack up the car and remove the oil pan

When you’re noticing water in your engine oil, the first step is to identify the source. So, jack up the car and remove the oil pan to get a better look. If you see any cracks or holes in the pan, you’ll need to patch them up and replace the oil pan before continuing.

Step-3: Inspect the oil pan for damage and Clean it

In order to get water out of engine oil, it is necessary to inspect the oil pan for damage. If there is a hole or crack in the oil pan, the water will leak in and contaminate the engine oil. The only way to fix this problem is by replacing the oil pan. For this, You’ll need a pan wrench to remove it. If you don’t have one, try using a large screwdriver or a pry bar to loosen it without damaging anything.

Now remove the drain plug and drain out any water in the oil pan. Use a rag and some carburetor cleaner to clean the inside of the oil pan. Don’t use any solvents or other cleaners that may damage the gasket and metal parts of this pan. Put the oil pan back on. However, If the oil pan is very dirty, you may need to replace it with a new one.

Step-4: Replace the gasket

A gasket is a seal that sits between two surfaces and helps keep liquids and other materials from passing between them. When the oil gets hot, it can create problems.

In order to get the water out of your engine oil, you will need to replace the gasket. However, it’s important to identify which gasket needs to be replaced. This can be done by inspecting the seals around your engine.

Step-5: Clean and Lubricate the Oil Pumps

After you have replaced the gasket, clean out all of the old oil from the engine. You will also need to lubricate the oil pumps so that they run smoothly. This will help prevent further damage and extend the life of your engine.

Step-6: Refill with new oil

When you are experiencing water in your engine oil, it’s important to take the appropriate steps to fix the issue. One of the most important steps is refilling the engine with new oil.

This will help get the water out of the engine and keep your vehicle running smoothly. Be sure to consult your vehicle’s owner’s manual for the correct type of oil to use and how much to add.

Step-7: Start the engine and check for leaks

When you’re finished, it’s time to start the engine. Turn the key to the “on” position and listen for any strange noises. If everything sounds normal, let the engine run for a few minutes. While it’s running, check all of the fluids again to make sure they haven’t leaked out.

Chemical Method

  • Using Additive to remove water from engine oil

In order to keep your car running smoothly, it is important to keep the engine oil clean. One way to do this is by using an additive to help remove water from the oil. This additive comes in a liquid or powder form and can be added to the oil crankcase directly.

It helps remove water by breaking down the water molecules into hydrogen and oxygen gas. The hydrogen gas then escapes from the engine while the oxygen gas is burned off.

There are several types of water absorbent additives available, and each one has its own benefits and drawbacks. When choosing an additive, it is important to consider the type of engine oil you are using, as well as the amount of water that needs to be removed.

Thermal Method

  • Using Heat to Vaporize Water

In the thermal method of water removal from engine oil, heat is used to vaporize the water so that it can be removed from the oil. The heat may be provided by an external source such as a heater, or it may be generated by the engine itself.

The most common way to remove the water is to use a condenser to cool the vaporized water and then collect it in a container. Some systems use a vacuum pump to draw the water out of the oil, while others use gravity to drain it off.

How to Prevent Water Getting into Engine Oil in The First Place

Water is a common enemy of car engines. It can cause all sorts of damage, including getting into the engine oil and causing corrosion and wear. While it’s not possible to completely prevent water from getting into your engine, there are some things you can do to minimize the risk. Here are a few tips on how to prevent water from getting into your engine oil in the first place:

  • Keep the car clean- One of the best ways to prevent water from getting into your engine oil is to keep your car clean and free of debris. Make sure that your engine bay is clear of leaves, dirt, and other materials that could potentially trap water.
  • Tune the car properly- Make sure your car is properly tuned and that all of your fluid levels are correct. A car that isn’t running properly will be more likely to experience problems with water infiltration.
  • Monitor Temperature gauge- To prevent water from getting into the engine oil, you should keep an eye on your temperature gauge. If it starts to run high, pull over and check things out. High temperatures can be a sign that there’s too much water in the system.
  • Change your oil and filter regularly- This will help remove any contaminants including water from the system.
  • Lookup for leaks- You should also regularly check your car for leaks, and fix any leaks you find immediately.

If you do end up with water in your engine oil, don’t panic! Take the steps we have mentioned above to remove the water and minimize the damage.
