Maintain correct crankcase ventilation and reliable engine performance with this Genuine Nissan Rocker Cover Breather Hose, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30Di diesel engine. This OEM breather hose connects the rocker cover to the air intake pipe, allowing blow-by gases to be recirculated through the engine's crankcase ventilation system while helping maintain proper engine operation.

Over time, breather hoses can become hard, brittle, cracked, or split due to constant exposure to engine heat, oil vapours, and vibration. A damaged breather hose can create vacuum leaks, allow oil vapour to escape into the engine bay, reduce engine performance, and permit unfiltered air to enter the intake system. Replacing a worn or damaged hose helps restore correct crankcase ventilation and protects your engine from unnecessary wear.

Manufactured to Genuine Nissan specifications, this rocker cover breather hose provides precise fitment, durable oil-resistant rubber construction, and reliable long-term performance. It is the ideal replacement component for engine servicing, preventative maintenance, or restoring your Nissan Patrol GU Y61 ZD30Di to its original factory condition.
