Excessive oil build up is a common problem experienced on the drag strip, drift track and occasionally on the street.

This kit 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 fitting features a compact and lightweight design. An 8AN O-Ring port is used to enable compact plumbing, and slotted holes allow multiple mounting options to suit all engines the Head Drain Fitting is 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. The supplied 10AN weld-on fitting is required to be welded to the sump.

Suitable for all Nissan RB20DE, RB20DET, RB25DE, RB25DET, RB26DETT, and RB30DET engines, including Neo engines.
