Head Oil Drain Fitting for Nissan RB011-001
A Head Oil Drain fitting is a part designed by Franklin Performance to help reduce excessive oil buildup in the cylinder head of Nissan RB twin cam series engines.
Excessive oil build up is a common problem experienced on the drag strip, drift track and occasionally on the street.
This fitting helps drain the oil back to the sump instead of building up in the head where it often ends up being forced out of tappet cover breathers and catch cans.
The head drain fittings feature a compact and light weight design. An 8AN O-Ring port is used to enable compact plumbing, and slotted holes allow multiple mounting options. For RB30 engines the fitting is positioned vertical as there is ample gearbox clearance. For RB20, RB25 and RB25 engines the fitting can be positioned at an angle to achieve the required clearance around the gearbox.
To fit the oil drain the frost-plug at the rear of the head is removed and two M6 holes are required to be tapped into the rear of the head.
Complete Head Oil Drain kits with high quality hose and fittings are available in our other listings.
Suitable for all Nissan RB20DE, RB20DET, RB25DE, RB25DET, RB26DETT, and RB30DET engines, including Neo engines.
