Parts for your 2008 Nissan Primera-Oil pump

2008 Nissan Primera oil-pump — what it does and when to sort it

Yes, the 2008 Nissan Primera uses an engine oil‑pump. Technical sources including the Nissan Primera P12 Workshop Manual (Section LU — Lubrication System), the QR20DE Engine Mechanical manual, and the diesel engine manuals for the Renault‑sourced F9Q 1.9 dCi and Nissan YD22DDTi note a positive‑displacement, crankshaft‑driven trochoid/gerotor pump integrated with the front cover. That oil‑pump is essential to engine longevity on all these P12‑series variants.

The oil‑pump’s job is simple but vital: push the right amount of oil, at the right pressure, through galleries to bearings, camshafts, and the timing gear so everything is cushioned by a film of oil. It also helps cool internal parts and feeds the chain tensioner on many Primera engines. If pressure drops, metal starts touching metal — and that’s where expensive damage kicks off.

There’s no routine replacement interval for the oil‑pump
