This kit includes two seals and two o-rings for each Vanos piston and a new o-ring for each plastic piston cap. These o-rings and seals feature an upgraded material (Viton) over the factory seals that tend to weaken and break down over time. The loss of oil pressure due to worn seals affects Vanos operation, reducing torque especially in the low and mid-RPM range.\u003c\/p\u003e\n\u003cp\u003eReplacing the M52TU\/M54 Vanos seals is done with the Vanos unit removed from the engine. It's a standalone repair - not really shared with any other work except a valve cover gasket or top-end valvetrain overhaul. We strongly suggest purchasing a top-end gasket kit that will include all of the other gaskets and seals needed when opening up the cylinder head of the engine.\u003c\/p\u003e\n\u003cp\u003eWith the Vanos disassembled, this is also the only time to replace the rings that cause “marble in a can” Vanos rattles. The Beisan anti-rattle rings are produced with a tighter size tolerance to reduce play and gaps and eliminate Vanos rattle.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"allcategories\"\u003e\n\u003cdiv class=\"allcategories_subsection_first\"\u003e\n\u003cbr\u003e\u003cb\u003eBMW Fitments:\u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003e3 Series\u003c\/b\u003e\u003cbr\u003eE46 (99-05) \u0026gt; 323Ci\u003cbr\u003eE46 (99-05) \u0026gt; 323i\u003cbr\u003eE46 (99-05) \u0026gt; 325Ci\u003cbr\u003eE46 (99-05) \u0026gt; 325i\u003cbr\u003eE46 (99-05) \u0026gt; 325xi\u003cbr\u003eE46 (99-05) \u0026gt; 328Ci\u003cbr\u003eE46 (99-05) \u0026gt; 328i\u003cbr\u003eE46 (99-05) \u0026gt; 330Ci\u003cbr\u003eE46 (99-05) \u0026gt; 330i\u003cbr\u003eE46 (99-05) \u0026gt; 330xi\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003e5 Series\u003c\/b\u003e\u003cbr\u003eE39 (97-03) \u0026gt; 525i\u003cbr\u003eE39 (97-03) \u0026gt; 528i 99-00\u003cbr\u003eE39 (97-03) \u0026gt; 530i\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003e5 Series\u003c\/b\u003e\u003cbr\u003eE60 \/ E61 (04-10) \u0026gt; 525i M54 (2004-2005)\u003cbr\u003eE60 \/ E61 (04-10) \u0026gt; 530i M54 (2004-2005)\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eX3 Series\u003c\/b\u003e\u003cbr\u003eE83 X3 (04-10) \u0026gt; X3 2.5i M54 (2004-2005)\u003cbr\u003eE83 X3 (04-10) \u0026gt; X3 3.0i M54 (2004-2006)\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eX5 Series\u003c\/b\u003e\u003cbr\u003eE53 X5 (00-06) \u0026gt; X5 3.0i M54\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eZ Series\u003c\/b\u003e\u003cbr\u003eE36\/7 \/ E36\/8 Z3 (96-02) \u0026gt; Z3 2.3\u003cbr\u003eE36\/7 \/ E36\/8 Z3 (96-02) \u0026gt; Z3 2.5\u003cbr\u003eE36\/7 \/ E36\/8 Z3 (96-02) \u0026gt; Z3 2.8 99-00\u003cbr\u003eE36\/7 \/ E36\/8 Z3 (96-02) \u0026gt; Z3 3.0\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eZ Series\u003c\/b\u003e\u003cbr\u003eE85 \/ E86 Z4 (03-08) \u0026gt; Z4 2.5i M54\u003cbr\u003eE85 \/ E86 Z4 (03-08) \u0026gt; Z4 3.0i M54\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Beisan Systems","offers":[{"title":"Default Title","offer_id":44025771360369,"sku":"BS001","price":144.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1088\/6742\/files\/VANOS-Seals-Repair-Kit-E46-E39-M52TU-M54-layout.jpg?v=1786645639","url":"https:\/\/www.parkautomotorsports.ca\/products\/vanos-seals-repair-kit-beisan-e46-323i-325i-328i-330i-e39-525i-528i-530i-e60-525i-530i-e83-x3-e53-x5-z3-e85-z4","provider":"Park Auto Motorsports","version":"1.0","type":"link"}
