Protect your engine from oil leaks and maintain proper lubrication return with this Genuine Nissan Oil Drain Back of Cylinder Head Gasket, designed to suit Nissan Patrol GU Y61 ZD30 engines. This OEM gasket seals the oil drain passage at the rear of the cylinder head, ensuring correct oil return flow back to the sump and preventing external oil leaks.

Over time, this gasket can become brittle, flattened, or cracked due to constant heat cycling and engine pressure. When it fails, it can allow oil to leak from the rear of the cylinder head, which may lead to oil loss, contamination of surrounding components, and long-term engine reliability issues if left unaddressed.

Manufactured to genuine Nissan specifications, this factory replacement gasket provides precise fitment, reliable sealing performance, and long-lasting durability to help maintain your Patrol’s engine integrity in harsh Australian driving conditions.
