NITTO’s oil drain for the Nissan RB20 RB25 and RB26 head helps alleviate the common issue of excessive oil build up in the head area. This problem is especially evident when the engine has a high volume oil pump installed. This RB oil drain also doubles as crankcase pressure relief so it’s great for multiple purposes on the RB series of engines.
Precision CNC machined from billet 6061-T6 aluminium alloy and finished with hard anodizing, this product will impress the most fastidious of buyers. There is no need for purchasing expensive aftermarket fittings as the NITTO RB Head Drain is supplied with o-ringed fittings that run a receiver groove and grub screw locking system.
These fittings can be installed on either side of the drain allowing hose routing to whatever side of the engine your installation calls for. For those that would prefer to utilise AN style fittings, an optional -10AN push in fitting is also available.
The head drain is supplied with 304 Stainless Steel mounting bolts and step by step instructions making it an easy to install, well priced, must have product.
Profiled to allow factory boost and water lines to run across back of cylinder head
