Parts for your 2008 Nissan Primera-Sump plug washers

2008 Nissan Primera sump plug washers

Yes — the 2008 Nissan Primera (P12-platform vehicles commonly registered through 2008 in some markets) uses a crush-type sump plug washer on the engine oil drain plug. Nissan’s own technical literature for the P12 (Engine Lubrication section of the Electronic Service Manual) specifies replacing the drain plug gasket at each oil change, and Nissan parts catalogues list an M14 oil drain plug gasket for the QR-series petrol and YD-series diesel engines (commonly referenced genuine part numbers include 11026-4N200 and 11026-01M02, depending on supersession). These sources confirm the sump plug washer is a standard, service-replaceable item on this model.

On the 2008 Nissan Primera, the sump plug washer does a deceptively important job. It’s a single-use, crushable gasket that sits under the sump drain bolt, flattening slightly as the bolt is torqued so it seals the oil pan. That crush action compensates for tiny surface imperfections and thermal expansion, keeping engine oil where it belongs — in the sump — even through hot Kiwi summers and crisp Aussie mornings.

Because it’s designed to deform once, reusing an old washer is asking for weeps, drips, or the temptation to overtighten the plug, which can stress threads in the alloy pan. Nissan’s service guidance is simple: fit a fresh washer at every oil change. Most Primeras of this era use an M14 copper or aluminium washer, stick with a quality part (genuine or reputable aftermarket) and the correct size for a proper seal.

Good workshop practice on a Primera service looks like this:

• Remove the old washer from the drain plug and clean the mating faces on the sump and plug.
• Fit a new crush washer, then tighten the plug to the factory spec — firm, not gorilla tight. A torque wrench is ideal.
• After refill, run the engine briefly, then check for any misting or drips around the plug.

Signs it’s time to pay attention? A faint oil halo on the plug, a single drip on the driveway after an oil change, or a washer that looks scored or work-hardened. If in doubt, replace it — they’re inexpensive insurance against oil loss and messy undertrays.

For owners clocking typical AU/NZ intervals, replacing the sump plug washer every service (roughly every 10,000–15,000 km or 12 months, per your schedule and driving conditions) keeps the Primera leak-free and the sump threads happy for the long haul.

Popular questions

What size sump plug washer does a 2008 Nissan Primera use?
Most 2008-registered Primeras (P12) use an M14 crush washer in copper or aluminium. Engine variants like the QR petrol and YD diesel families share this size. To be safe, match by VIN or grab the genuine-spec washer commonly referenced under Nissan p/ns 11026-4N200 or 11026-01M02 (subject to supersessions).

How often should the sump plug washer be replaced?
Every oil change. It’s a single-use crush gasket, and Nissan’s service documentation calls for replacement each time the plug is removed. Many Aussie and Kiwi workshops tie this to 10,000–15,000 km or 12 months, depending on your maintenance schedule and driving conditions.

Can the sump plug washer be reused?
Best not. Reusing an old washer risks small leaks or encourages overtightening, which can damage the sump threads. A fresh, correct-size washer is cheap and keeps the Primera tidy and sealed.
