It mounts over the cylinder head and valve-train assembly, sealing the upper engine and providing the correct interface for the valve-cover gasket and oil-filler components. This is the latest revision in a supersession chain that replaces earlier D3 valve covers 31286262, 31330239, and 31338169 — making it the correct replacement for all earlier D3 valve-cover numbers.

Always replace the valve-cover gasket (\u003ca href=\"\/products\/volvo-penta-gasket-31430317\"\u003e31430317\u003c\/a\u003e) when installing a new cover.

If oil leakage persists after a gasket replacement, inspect the cover sealing flange for distortion. A warped cover will not seal correctly regardless of gasket condition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I confirm this is the right cover for my engine?\u003c\/strong\u003e\u003cbr\u003eA: Match your engine model and serial number to the Volvo Penta D3 cylinder-head diagram. If your engine currently has an earlier valve-cover number (31286262, 31330239, or 31338169), 31430316 is the current OEM replacement.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe supersession chain on this part is worth knowing — customers with older D3 engines often search by their existing part number (31286262, 31330239, or 31338169) and aren’t sure if 31430316 is the right replacement. It is. The updated cover is the current OEM part for all D3 applications that previously used any of those earlier numbers. The most common oversight during valve cover replacement is not replacing the gasket at the same time — always pair 31430316 with \u003ca href=\"\/products\/volvo-penta-gasket-31430317\"\u003egasket 31430317\u003c\/a\u003e.
