## ⚙️ Key Features

-   Crankcase breather pipe for use with the oil separator on TAD1140-42VE industrial engines
-   0.231 kg
-   Listed for 4 applications in the TAD family
-   Carries both crankcase vapour and separated oil in the closed-ventilation system

## 🔌 Function

Routes crankcase vapour into the oil separator and the separated oil back out of it, so the engine breathes at a controlled rate and the oil it carries is returned rather than lost.

## ⚠️ Common Signs of Failure

-   Oil mist or vapour escaping around the pipe under load
-   Oil sweating down the block from a joint
-   Filler cap or dipstick lifting from crankcase pressure
-   Bore furred with sludge and partly blocked on strip-down
-   Pipe hardened, cracked or split at a bend

## 🛠️ Service Notes

-   Clean or service the separator at the same time - a blocked breather pipe and a loaded separator usually go together
-   If crankcase pressure is still high after fitting, the engine's blow-by is the fault to chase
