NITTO's oil drain for the Nissan RB20/25/26 head helps alleviate the all too 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.

Whether you look at this product as an oil drain or crankcase pressure relief system, there is no doubt that it is a highly beneficial product on any built RB DOHC engine.

Precision CNC machined from billet 6000 series 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.
