Overview
The Volvo Penta 31430316 is the current genuine OEM valve cover for Volvo Penta D3 marine diesel engines. 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. It pairs with matching gasket 31430317, which should always be replaced at the same time.
Compatible Applications
- Volvo Penta D3-110I (generations D–H and earlier)
- Volvo Penta D3-140A / D3-140I (generations D–H and earlier)
- Volvo Penta D3-150I (generations D–H and earlier)
- Volvo Penta D3-170A / D3-170I (generations D–H and earlier)
- Volvo Penta D3-200A / D3-200I (generations D–H and earlier)
- Volvo Penta D3-220A / D3-220I (generations D–H and earlier)
Volvo Penta revised the D3 valve cover several times during production. Confirm your engine model and serial number against the applicable Volvo Penta cylinder-head diagram before ordering. If your engine currently carries an earlier valve-cover number (31286262, 31330239, or 31338169), 31430316 is the current replacement.
Serial Number Requirements
Always confirm your engine model and serial number using the Volvo Penta D3 cylinder-head parts diagram. The valve cover has been revised multiple times across D3 production — matching by serial number ensures you receive the correct current revision for your engine.

Installation Notes

Technical FAQ
Q: What earlier part numbers does 31430316 replace?
A: 31430316 is the current revision in a supersession chain: 31286262 → 31330239 → 31338169 → 31430316. If your engine carries any of these earlier numbers, 31430316 is the correct current replacement.
Q: Do I need a new gasket when replacing the valve cover?
A: Yes. Always replace the valve-cover gasket (31430317) when installing a new cover. Reusing an old gasket risks oil leakage after reassembly.
Q: Can a warped valve cover cause oil leaks even with a new gasket?
A: Yes. 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.
Q: How do I confirm this is the right cover for my engine?
A: 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.
Parts Desk Insights
The 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 gasket 31430317. It’s also worth inspecting the oil-filler pipe and pressure sensor O-ring while the cover is off, since access is easy at that point.
