Nissan Skyline R32 Cylinder Head Oil Drain Fitting

Nissan Skyline R32 Cylinder Head Oil Drain Fitting

This head drain is designed to help reduce excessive oil buildup and pressure in the cylinder head of Nissan RB twin cam series engines. A common problem experienced on the drag strip, drift track and occasionally on the street. This drain helps drain the oil back to the sump instead of building up in the head where it often ends up being forced out of cam cover, breather systems and catch cans. In addition this drain equalises crankcase and cylinder head pressures.

The drain is a CNC machined fitting offering a low-profile to provide maximum clearance between the rear of the engine and firewall.

The fitting is supplied with: -10AN Fitting Aluminum Fitting 2x Cap Screws O-Ring

Extra fittings are not included in this auction, please check my other auctions for complete kits.

The thread in the drain fitting is 3/8" NPT. which means they are thinner than others on the market and allows for additional clearance (fitting also available at an additional cost)

To fit the oil drain 2x M6 holes need to be tapped into the rear of the head.
