TLG Cylinder Head Oil Drain Fitting to suit Nissan RB20/RB25/RB26/RB30
This is a fitting designed to help reduce excessive oil buildup in the cylinder head of Nissan RB twin cam series engines by returning excess oil to the sump. This is a common problem experienced on the drag strip, drift track and occasionally on the street.
CNC machined low-profile fitting to provide maximum clearance between the rear of the engine and firewall
Locally produced, not mass produced Chinese garbage!
The fitting is supplied with:
1x Aluminium Fitting
2x Cap Screws
1x AN10 Sump Weld-on
2x Proflow Full-flow AN10 90deg fittings
1x Metre of Proflow AN10 hose
The thread in the drain fitting is now 3/8" NPT to allow plenty of clearance to the gearbox bellhousing
The head drain fittings are available in Black only
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.
Suitable for all Nissan RB20DE, RB20DET, RB25DE, RB25DET, RB26DETT, and RB30 engines, including RB25 Neo engines
