# 21475226 Separator | Genuine Volvo Penta Part

## 🔧 Product Description

A complete crankcase ventilation separator that removes oil mist from blow-by gases before the gases are returned to the engine intake or discharged through the ventilation system.

## ⚙️ Key Features

-   Genuine Volvo Penta separator assembly
-   Reduces oil carry-over from crankcase gases
-   Heavy-duty housing for industrial engine service
-   Protects intake and turbocharger components from oil contamination
-   Service or replacement is controlled by the engine ventilation arrangement
-   Engine type: Heavy-duty turbocharged diesel

## 🔌 Function

Separates lubricating-oil droplets from crankcase blow-by gas and returns the oil to the engine.

## ⚠️ Common Signs of Failure

-   Oil mist around the breather
-   Oil consumption increases
-   Oil contamination in the intake system
-   Breather restriction or external oil leakage

## 🛠️ Service Notes

-   At 2.395 kg this is one of the heavier separators in the catalogue — support the housing itself when removing or refitting it rather than letting its weight hang on the drain or vent connections
-   Check the drain line back to the sump is clear before condemning the separator, since a blocked drain floods a sound unit and produces the same symptoms as a failed one
-   A rise in crankcase pressure can be blow-by from worn rings rather than a failed separator — measure it before renewing the unit
