What This Gasket Does
The 30788492 is the OEM sealing gasket between the oil filter housing / bracket and the engine block on Volvo Penta D3-series marine diesel engines. 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.

Documented across D3 D-through-H generation engines. Confirm the exact engine model and serial number using the Volvo Penta oil-filter assembly diagram before ordering — D3 lubrication-system layouts can vary between engine revisions.
Serial Number Fitment Notice
Use your engine serial number to pull the correct Volvo Penta D3 oil-filter assembly diagram and verify that 30788492 is shown at position 7 before ordering. This is the most reliable confirmation across D3 engine generations.
When to Replace
- Engine oil leaking from the oil filter housing-to-block joint
- Oil filter housing removed for any reason
- Gasket is flattened, torn, brittle, or oil-soaked
- Oil-system or lubrication-system service disturbs the housing joint
A used, compressed gasket should not be reused after the housing has been removed.
Installation Notes
Thoroughly clean both mating surfaces and remove all traces of the old gasket without gouging the aluminum sealing faces. Inspect the oil filter housing, mounting fasteners, and nearby oil passages while the assembly is apart. Tighten the flange screws evenly and to the Volvo Penta service-manual torque specification for the D3 oil-filter housing to ensure a consistent, leak-free seal.
Technical FAQ
Q: Is 30788492 the same as the oil filter itself?
A: No. This is the housing gasket that seals the oil filter housing bracket to the engine block. The oil filter cartridge is a separate item — see the Volvo Penta D3 Oil Filter Kit 30788490 for the filter element.
Q: How many gaskets does one D3 engine require?
A: One gasket per engine (quantity 1 as shown in the D3 parts diagram).
Q: Can I reuse the old gasket after removing the housing?
A: No. Once compressed and disturbed, this gasket should be replaced to ensure a reliable oil-tight seal on reassembly.

Parts Desk Insights
This gasket comes up most often when customers are chasing an oil leak at the filter housing on D3 engines, or when the housing is already off for a service. 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.
