The Nissan Skyline R32 and R33 GTR Engine Block Oil Gallery Plug for the RB26DETT is a precision-engineered blind plug designed to seal an unused oil passage in the main oil gallery system. Located on the side of the cylinder block in the flange area where the oil filter housing mounts, this solid steel plug maintains proper oil pressure and prevents leaks, ensuring reliable lubrication of the crankshaft, bearings, and other critical engine components. Its correct installation is essential during engine rebuilds, cleaning, or oil system maintenance, as a missing or damaged plug can compromise oil circulation and overall engine integrity.
Manufactured to exact Nissan specifications, this blind oil gallery plug is typically M12x8 in size and is required in one location per cylinder block. Its robust design withstands high-pressure conditions within the RB26DETT lubrication system, supporting long-term durability and performance. Unlike later RB26DETT variants in the R34 Skyline GT-R, this plug is specific to R32 and R33 models, reflecting minor oiling system revisions in the NEO-spec and BNR34 blocks.
Terra Firma Automotive supplies only genuine Nissan components, guaranteeing precision fitment and optimal reliability. Using the correct RB26DETT engine block oil gallery plug ensures that your R32 or R33 GTR maintains proper oil system integrity, protects critical internal components, and supports the high-performance demands these legendary engines are known for.
