The Nissan Stagea C34 260RS Cylinder Head Oil Jet (Front) for the RB26DETT engine is a precision-engineered steel component designed to deliver pressurized oil from the cylinder block into the cylinder head. Measuring approximately 5mm long by 5mm in diameter, this jet is installed in a machined port on the upper deck of the block beneath the head gasket, typically in the forward oil feed positions. Its function is to provide consistent lubrication to the cylinder head and valvetrain, even under high-RPM and boosted conditions.
Featuring a calibrated central orifice of about 1mm, the oil jet meters precise amounts of oil into the cylinder head galleries, ensuring proper lubrication for camshaft bearings, hydraulic lash adjusters, and other valvetrain components. This targeted oil flow reduces friction, dissipates heat, and prevents premature wear or failure in the RB26DETT engine. Unlike the solid rear oil plug that seals unused passages, this front jet actively directs oil where it is needed, maintaining reliability and efficiency for the Nissan Stagea C34 260RS.
The oil jet is commonly replaced during cylinder head removal, gasket replacement, or full engine rebuilds to prevent restrictions caused by debris or damage. Terra Firma Automotive provides genuine Nissan components to ensure your RB26DETT engine maintains optimal lubrication, peak performance, and long-term durability, supporting the high-performance demands of the Nissan Stagea C34 260RS.
