Maintain proper crankcase ventilation and engine performance with this Genuine Nissan Rear Breather Hose to Intake Manifold, designed to suit Nissan Patrol GU Y61 models fitted with the TB45 4.5L petrol engine. This OEM breather hose connects the PCV (Positive Crankcase Ventilation) valve at the rear of the rocker cover to the intake manifold, allowing crankcase gases to be safely recirculated through the engine's intake system for efficient combustion and emissions control.

Over time, the original rubber hose can become hard, brittle, crack, or split due to constant exposure to engine heat and oil vapours. A damaged breather hose can create a significant vacuum leak, leading to rough idle, poor engine performance, increased fuel consumption, and lean running conditions. Replacing a worn hose restores the integrity of the PCV system and helps maintain smooth engine operation.

Manufactured to Genuine Nissan specifications, this rear breather hose is built for precise fitment, long-lasting durability, and dependable performance. It is the ideal replacement for routine maintenance, engine repairs, or restoring your Nissan Patrol to factory operating condition.
