SPOOL

RB Cylinder Head Oil Drain Kit

Here is a kit designed to help reduce excessive oil buildup in the cylinder head of Nissan RB series engines. This is a common problem experienced on the drag strip and occassionally 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 kit contains the OIL DRAIN that fits in the back of the cylinder head ( where the OEM welsch plug resides ) , geniune dash 10 SPEEDFLOW FITTINGS , 1 meter of HOSE and a WELD ON FITTING for the sump return. (Available in either alumiminium or steel - depending on sump used.)

Complete kit $250 - see pic 2

Oil drain $110 - see pic 4

For comparison purposes, the picture below shows that the SPOOL oil drain only protrudes 27mm out of the rear of the cylinder head, where as a dash 10 speed flow fitting ( which is often used ) is 49mm.
