Parts diagrams place 3886951 directly beside oil dipstick tube 3593955 and the dipstick assembly, where it forms part of the oil-level tube arrangement in the lubrication system. This is not a generic threaded nipple — its position is specific to the D4\/D6 dipstick tube arrangement, and it should not be confused with other nipples in the same lubrication system (such as 423067 or 3583695) that occupy different diagram positions. Confirm engine model, suffix, and serial number against the lubricating-system diagram before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eD4 F-Series:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D4-180I-F\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D4-225A-F \/ D4-225I-F\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D4-260A-F \/ D4-260D-F \/ D4-260I-F\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D4-300A-F \/ D4-300D-F \/ D4-300I-F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eD6:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D6-280A \/ D6-280I\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-310A \/ D6-310D \/ D6-310I\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-330A \/ D6-330D \/ D6-330I\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-350A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-370A \/ D6-370D \/ D6-370I\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-400A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-435D \/ D6-435I\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eD4 and D6 engines underwent production changes that can affect surrounding dipstick tubes, brackets, guides, and hardware.

The most common issue is assuming any similar-looking nipple will work — the D4\/D6 lubrication system uses several different nipples at different positions, and matching by engine serial number and diagram position is the only reliable method. If the dipstick tube is being replaced, inspect 3886951 at the same service visit and replace it if there is any sign of corrosion or damage.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564037177380,"sku":"3886951","price":38.7,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_89cd94d2-ab15-473a-96e5-0b1ad89607d7.png?v=1788650048","url":"https:\/\/marisolmarine.com\/products\/volvo-888","provider":"Marisol Marine Company","version":"1.0","type":"link"}
