Parts for your 2017 Subaru Exiga-Oil pump

2017 Subaru Exiga oil pump — what it does, why it matters, and when to sort it

Yes, the 2017 Subaru Exiga (sold in Japan as the Exiga Crossover 7, typically with the FB25 2.5‑litre boxer) is fitted with an engine oil pump. This isn’t optional kit — it’s a crankshaft‑driven, internal gerotor/trochoid pump housed in the front cover. That’s confirmed in Subaru’s FB‑series Workshop/Service Manual lubrication section and in Subaru FAST/parts catalogues for the Exiga Crossover 7, which list the complete oil pump assembly and related seals for the FB engine family.

The oil pump’s job is simple but critical: push engine oil under pressure through the crank and rod bearings, camshafts, timing chains, AVCS/VVT components and galleries, keeping friction down and temperatures in check. Without good pressure, the boxer will complain quickly — think rattles, warning lamps, and expensive wear.

For the 2017 Exiga, the oil pump isn’t a routine replacement item
