It replaces both factory rigid oil line assemblies with a flexible -4AN PTFE braided oil feed line and high-temperature silicone oil return hose system.\u003c\/p\u003e\n\u003cp\u003eA common problem with the original oil lines is rotation leak failure at the joined section between the rigid pipe and its end fitting. This can affect both the oil feed line banjo fitting and the oil return line flange or end fitting. Once the fitting begins to rotate independently from the pipe, oil can seep directly from the joint.\u003c\/p\u003e\n\u003cp\u003eReplacing only the copper washers or return line O-ring will not repair the problem when oil is leaking from the rotating pipe-to-fitting connection. This kit removes both original rigid line assemblies and replaces them with flexible hose systems that reduce stress on the sealing points and simplify future turbocharger service.\u003c\/p\u003e\n\u003cp\u003eThe oil feed side uses a -4AN PTFE braided stainless steel hose with a 1.8mm restricted turbo-side banjo bolt to help control oil flow and reduce the risk of turbo over-oiling. The return side uses a high-temperature silicone hose, billet aluminum drain fitting, Viton O-ring, and protective heat sleeve.\u003c\/p\u003e\n\u003cp\u003eThis kit includes both the\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNM-11657534454-BRAIDED- \u003cspan\u003eBMW Turbo Oil Feed Line Kit MINI R55-R61 Cooper S\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNM-11658617069 \u003cspan\u003eBMW Turbo Oil Drain Hose Kit\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cem\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eReplaces both factory turbo oil feed and return line assemblies\u003c\/li\u003e\n\u003cli\u003eDesigned to repair rotation leaks on both oil feed and oil return sides\u003c\/li\u003e\n\u003cli\u003e1.8mm restricted turbo-side fitting helps control turbo oil flow\u003c\/li\u003e\n\u003cli\u003eFlexible PTFE feed line and high-temperature silicone return hose\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Minisport.com.au","offers":[{"title":"Default Title","offer_id":67652759191862,"sku":"11657534454-KIT","price":199.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/files\/20261008_120936-Photoroom.jpg?v=1791423842","url":"https:\/\/minisport.com.au\/products\/mini-cooper-s-jcw-n14-n18-turbo-oil-feed-return-line-kit-r55-r61-11657534454-kit","provider":"Minisport","version":"1.0","type":"link"}
