After years of racing experience and hours of R & D Hi Octane Racing has produced these cylinder head oil drain fittings.

One major problem with the RB series engine's is oil pooling in the cylinder head. At high RPM all the oil is pumped up into the cylinder head and the engine doesn't have adequate return galleries. This will cause the sump to be drained and eventually the engine will suffer oil surge which can cause damage to engine bearings and result in engine failure.

Hi Octane Racing designed the Head Drain to help fix this problem, it was designed with an off set thread to allow as much oil as possible to be drained.

For GT-R owners we strongly recommend the use of the Hi Octane Racing Cam Cover Baffles along with the Hi Octane Racing Sump Extension which has a provision to run this drain and return the oil directly back to the sump.

Note: Engine will need to be removed to install this item and welsh plug in the back of the head removed, dill and tap 2 small holes.all that is needed then is lines and fittings.
