How To Clean Oil Out Of Intake Manifold

Have you ever put oil in the intake manifold, or are you still having trouble getting it all out? Here are a few helpful tips to help you clean and clear out the intake manifold.

What is the Intake Manifold?

The intake manifold is the portion of an engine that supplies the air/fuel mixture to the cylinders. In most modern cars, the intake manifold is integrated into the cylinder head. The primary function of the intake manifold is to evenly distribute the air/fuel mixture to each cylinder.

The air/fuel mixture enters the intake manifold through the throttle body. The throttle body is controlled by the accelerator pedal and regulates the amount of air that enters the engine. The air then passes through the intake valves and into the cylinders.

The intake manifold can become dirty over time due to oil leaks or other deposits. This can cause a loss of power and decreased fuel economy. A dirty intake manifold can be cleaned by removing it from the engine and soaking it in a cleaning solution.

Symptoms of an Oil Leak

If you think you have an oil leak, check your engine oil level first. If it’s low, you may just need to add more oil. If the oil level is normal, look for these other signs of an oil leak:

-A burning oil smell coming from the engine
-Smoke coming from the engine (white smoke if it’s burning coolant)
-A puddle of oil beneath your parked car
-Exhaust fumes in the cabin of your car
-Low oil pressure warning light on your dash

Diagnosing and Fixing an Oil Leak Into the Intake Manifold

When you have an oil leak into the intake manifold, it is important to diagnose and fix the problem as soon as possible. An oil leak can cause a number of problems, including engine damage, so it is not something that should be ignored.

There are a few different ways that oil can leak into the intake manifold. The most common way is through a leaking gasket or seal. If you have a leaking gasket or seal, you will need to replace it. Another way that oil can leak into the intake manifold is through a cracked intake manifold. If you have a cracked intake manifold, you will need to replace it.

Once you have diagnosed the problem, you can begin to fix it. If you have a leaking gasket or seal, you will need to replace it with a new one. If you have a cracked intake manifold, you will need to weld it back together or replace it. Once you have fixed the problem, you can then clean up any oil that has leaked into the intake manifold.

How To Clean Out Oil From Your Intake Manifold

If your car’s intake manifold is dirty, it can cause a decrease in performance and fuel economy. A clean intake manifold is essential to the proper functioning of your car.

To clean your intake manifold, you will need:

-A can of carburetor cleaner

-A stiff brush

-A vacuum cleaner with the hose attachment

-Rags or paper towels


Step 1: Remove the air filter. This will give you better access to the carburetor and intake manifold.

Step 2: Spray carburetor cleaner into the carburetor throat and into the intake manifold. Use a stiff brush to scrub away any deposits or build-up.

Step 3: Use the vacuum cleaner to suction any dirt or debris from the intake manifold. Be sure to get all of the nooks and crannies.

Step 4: Wipe down the inside of the intake manifold with a rag or paper towel to remove any residual cleaner or build-up. Be sure to wear gloves while doing this.

Step 5: Reinstall the air filter and start your engine. Let it run for a few minutes to make sure everything is working properly.


To conclude, cleaning an oiled intake manifold is a straightforward process that anyone can do with the right tools and guidance. First, remove the plenum chamber and any debris that may have accumulated on it. Next, use a stiff wire brush to remove all the oil and gunk from the walls of the plenum chamber. Finally, flush the chamber out with a strong solvent like brake cleaner to remove any lingering traces of oil.
