However the stock oil-gallery orifice has a hole that is too large which allows too much oil to be delivered to the cylinder head which will cause the problems as listed below. \u003cbr\u003e  (1) Too much blow-by Gas\u003cbr\u003e (2) Blowing engine oil\u003cbr\u003e (3) Leaking oil through the valve guides\u003cbr\u003e (4) Insufficient oil delivery to the crank journal\u003cbr\u003e (5) Allows air pockets into the system from when the oil pan is under horizontal G-Forces. \u003cbr\u003e  The TOMEI oil gallery orifice was designed from the experience and data we had obtained from the development of our N1 endurance and drag racing engines. By restricting the diameter of the orifice to φ1.5mm (Normal is φ2.0mm) we succeeded in securing enough lubrication to the camshaft and valve while maintaining the correct amount of oil in the oil pan which resolved the common problems. (For added Blow by prevention we recommend using the TOMEI 3D Profile pistons.)\u003cbr\u003e APPLICATION:BNR32\/BCNR33\/BNR34\u003cbr\u003e ENGINE:RB26DETT\u003c\/div\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"width: 35%;\"\u003eRemarks\u003c\/td\u003e \u003ctd style=\"width: 65%;\"\u003e\u003cdiv align=\"left\"\u003eφ1.5\u003cbr\u003e Combine with STD orifice to use \u003cbr\u003e For RB25 and 20 solid type engines ONLY (not to be used on lash type RB20 and RB25 engines)\u003c\/div\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"width: 35%;\"\u003eNotes\u003c\/td\u003e \u003ctd style=\"width: 65%;\"\u003e\u003cdiv align=\"left\"\u003eImages are for illustration purpose only.
