It prevents engine oil from leaking at the housing-to-block mounting joint. This is a specific D3 lubrication-system gasket — not a general-purpose seal — and it should be replaced any time the oil filter housing is removed or disturbed.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D3-110I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-140A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-140I-E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-150I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-170A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-170I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-200A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-200I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-220A-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D3-220I-D \/ E \/ F \/ G \/ H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDocumented across D3 D-through-H generation engines.

It’s an inexpensive part relative to the labor of opening the oil-filter assembly — always replace it rather than reuse the original. If the housing itself shows corrosion or damage at the sealing face, address that before installing the new gasket or the leak will return.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43766245457956,"sku":"30788492","price":50.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/727d18f4-71bd-4a9a-ad80-f4a08a73b442.png?v=1788842701","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-oil-filter-housing-gasket-30788492","provider":"Marisol Marine Company","version":"1.0","type":"link"}
