What does oil in your intake mean?
What does oil in your intake mean?
If it’s more than 2-3 ounces (1-2 shot glasses) then you most likely have either a failed PCV hose or a vacuum leak that causes oil to be sucked into the intake. It might also come from some combination of too much oil, extended high RPMs or aggressive cornering pushing oil into the intake.
Where does the air go in a supercharger?
A hot topic for debate recently has been Supercharger designs and the impact of Inlet Air Temperatures (IATs) delivered to the engine. On the topic of supercharger layout, there are two common types. One where the air exits the supercharger downwards, and the other upwards.
What happens when there is oil in the intake manifold?
Here comes the intake or inlet manifold. It is a series of tubes that evenly distribute the air into the cylinders. It is bad news when there is oil in intake manifold. Why does this happen and what problem it can lead to? The inlet manifold passes the air to the cylinders through some valves.
How much boost does a supercharger have?
The run start point has about 11 PSI of boost and the end point just over 21 PSI. Whilst the supercharger outlet temperature almost doubles the IAT is well under control and increases by less than 30%.
What are the intercoolers on a Harrop supercharger?
Below are cross-sections of two Harrop Supercharger manifolds, on the left a downwards outlet and on the right an upwards outlet. Green highlighted surfaces are the in-manifold intercoolers. Red arrows indicate the general, schematic airflow path.

When to worry about oil in air intake?
It is the first component to look into when the problem occurs although you should not be worried if there is a small amount of oil in air intake. It is not rare to have blocked PCV valves on cars with less than 100,000 mileage. You have to examine the entire PCV system.

How does oil get into the air filter?
The PCV valve is similar to an engine oil filter in that it eventually becomes clogged with excessive debris (in this case — engine oil) and should be replaced as recommended by your vehicle’s manufacturer. If the PCV valve is not replaced as recommended, excessive oil will blow through the PCV valve and enter the air intake system.
