The Nissan Skyline R32, R33, and R34 Engine Block to Oil Pump Locating Dowel Pin for RB26, RB25, and RB20 engines is a precision component designed to ensure perfect alignment between the cylinder block and oil pump assembly. Positioned in a machined hole on the front of the block, within the oil pump mounting flange, this steel pin engages with the corresponding hole in the oil pump housing, guaranteeing the inlet and outlet passages align perfectly with the engine’s main oil gallery. Misalignment can compromise oil flow, reduce pressure, or cause leaks, risking lubrication failure to critical components such as the crankshaft, camshafts, and turbochargers.
Manufactured to meet OEM specifications, this small dowel pin, approximately 7mm long and 4mm in diameter, is essential for maintaining the integrity and performance of RB-series engines, particularly under high-stress, high-revving conditions. It is commonly inspected or replaced during oil pump servicing, timing belt replacement, or complete engine rebuilds to ensure precise fitment and reliable operation.
Terra Firma Automotive supplies only genuine Nissan parts, ensuring your Skyline engine maintains optimal oil flow and component longevity. Installing the correct Engine Block to Oil Pump Locating Dowel Pin safeguards the lubrication system, prevents premature wear, and supports the high-performance demands of the R32, R33, and R34 Skylines. Trust Terra Firma Automotive for authentic Nissan components engineered for precision and durability.
