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. By restricting the diameter of the orifice to 1.5mm (Normal is 2.0mm) Tomei has succeeded in securing enough lubrication to the camshaft and valve while maintaining the correct amount of oil in the oil pan which resolved these common problems:\n\u003cul\u003e\n \t\u003cli\u003eToo much blow-by gas,\u003c\/li\u003e\n \t\u003cli\u003e\u003cspan class=\"apple-style-span c1\"\u003eBlowing engine oil,\u003c\/span\u003e\u003c\/li\u003e\n \t\u003cli\u003e\u003cspan class=\"apple-style-span c1\"\u003eLeaking oil through the valve guides,\u003c\/span\u003e\u003c\/li\u003e\n \t\u003cli\u003e\u003cspan class=\"apple-style-span c1\"\u003eInsufficient oil delivery to the crank journal,\u003c\/span\u003e\u003c\/li\u003e\n \t\u003cli\u003e\u003cspan class=\"c1\"\u003e\u003cspan class=\"apple-style-span\"\u003eAllows air pockets into the system from when the oil pan is under horizontal G-Forces.\u003c\/span\u003e\u003cspan class=\"apple-converted-space\"\u003e  \u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstrong\u003eNotes\u003c\/strong\u003e\n\u003cul\u003e\n \t\u003cli\u003eCombine with STD   orifice to use\u003c\/li\u003e\n \t\u003cli\u003eFor RB25\/R20 with solid type engines only!\u003c\/li\u003e\n \t\u003cli\u003ePrice is for each oil gallery orifice\u003c\/li\u003e\n \t\u003cli style=\"list-style-type: none;\"\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":42453600632999,"sku":"TB2040-NS05A","price":7.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/products\/thumbnail_946851_Tomei_TB2040-NS05A_FG01-01-1.jpg?v=1653073963","url":"https:\/\/www.straightsiximports.com\/en-us\/products\/tomei-oil-gallery-orifice-rb26-rb25-rb20","provider":"Straight Six Imports","version":"1.0","type":"link"}
