⚙️ 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
