Parts for your 2014 Toyota Bb-Oil pump

2014 Toyota bB oil pump — what it does and when to service it

Based on the Toyota Electronic Parts Catalogue for the QNC20/21/25 series, the Toyota bB Repair Manual (Engine – Lubrication System), and the Daihatsu 3SZ‑VE / K3‑VE engine workshop manuals used in the 2014 bB, this model is fitted with a crankshaft‑driven, internal trochoid oil pump. So yes, an oil pump is absolutely relevant to the 2014 Toyota bB.

In the bB’s 1.3 K3‑VE or 1.5 3SZ‑VE engines, the oil pump sits in the front cover and is driven off the crank. Its job is to pull oil from the sump, push it through the filter and galleries, and keep every moving bit—bearings, cams, chain and lifters—properly lubricated and cooled. Without stable oil pressure, wear skyrockets and the engine won’t last the distance.

While the pump itself isn’t a regular replacement item, the best way to look after it is simple: keep the oil clean and the level right. Use a quality oil and filter meeting the owner’s manual spec (in Aus/NZ conditions, quality 5W‑30 meeting API SN or better is common
