NITTO's oil drain to suit fit the Nissan Skyline & GTR Engine RB20/25/26 to help the head release oil being forced to the back of the head under load. With out a head return fitted the oil cant get out quick enough and the only place it has to go is out the cam cover breathers making a terrible mess! This problem is especially evident when the engine has a high volume oil pump installed.

CNC machined from billet 6000 series aluminium and finished with hard anodizing, this 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 (# NIT-OIL-RBD10) 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.
