Proflow’s head oil drain fitting kit is designed to reduce excessive oil build up on the drag strip, drift track and on the street. The cylinder head fitting in 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 valve cover breathers and into catch cans. It seals with an o-ring in the head and features a compact -08AN O-Ring port and slotted holes to allow you to change the angle and position of the fitting depending on clearances around the gearbox on different RB engines. To fit the oil drain fitting, 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 (drawing below). Black anodised for a long lasting finish .
