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. \u003c\/p\u003e\n\u003cp\u003e(1) Too much blow-by Gas\u003c\/p\u003e\n\u003cp\u003e(2) Blowing engine oil\u003c\/p\u003e\n\u003cp\u003e(3) Leaking oil through the valve guides\u003c\/p\u003e\n\u003cp\u003e(4) Insufficient oil delivery to the crank journal\u003c\/p\u003e\n\u003cp\u003e(5) Allows air pockets into the system from when the oil pan is under horizontal G-Forces.\u003c\/p\u003e\n\u003cp\u003eThe 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 Æ1.5mm (Normal is Æ2.0mm) 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.)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable class=\"table table-striped mb-0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eengine\u003c\/th\u003e\n\u003ctd\u003eNISSAN RB26DETT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003emodel\u003c\/th\u003e\n\u003ctd\u003eNISSAN 32 GT-R, NISSAN 33 GT-R, NISSAN 34 GT-R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003emain category\u003c\/th\u003e\n\u003ctd\u003eOIL LUBRICATION\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003esub category\u003c\/th\u003e\n\u003ctd\u003eOIL GALLERY ORIFICE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eshipping size\u003c\/th\u003e\n\u003ctd\u003e10 x 8 x 1 inch \/ 23 x 18 x 3 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eshipping weight\u003c\/th\u003e\n\u003ctd\u003e1 lbs \/ 0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\" ø1.5\u003c\/p\u003e\n\u003cp\u003e\" Combine with STD orifice to use\u003c\/p\u003e\n\u003cp\u003e\" For RB25\u0026amp;20, solid type engines only (not to be used on lash type RB20 \u0026amp; RB25 engines)\u003c\/p\u003e\n\u003c!--\/ Vehicle Applications --\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eVehicle Fitments:\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth width=\"100\" align=\"left\"\u003eYear\u003c\/th\u003e\n\u003cth width=\"125\" align=\"left\"\u003eMake\u003c\/th\u003e\n\u003cth width=\"150\" align=\"left\"\u003eModel\u003c\/th\u003e\n\u003cth width=\"80\" align=\"left\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1991 - 1998\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e240SX\u003c\/td\u003e\n\u003ctd\u003eLE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1989 - 1998\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e240SX\u003c\/td\u003e\n\u003ctd\u003eSE, Base\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1989 - 1990\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e240SX\u003c\/td\u003e\n\u003ctd\u003eXE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c!-- Vehicle Applications \/--\u003e","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":45481521479737,"sku":"0LLXY","price":6.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/8632\/8889\/files\/Tomeixx-6.jpg?v=1772798610","url":"https:\/\/shop.throttletherapynation.com\/products\/tomei-oil-gallery-orifice-rb26dett","provider":"Throttle Therapy Nation ","version":"1.0","type":"link"}
