2012 Nissan Pulsar oil cap — what it does and how to look after it

Based on Nissan technical publications — including the 2012–2013 Nissan Pulsar (C12 hatch/B17 sedan) Owner’s Manual, Nissan service manuals for the MR18DE/HR16DE/MR16DDT engines, and Nissan’s electronic parts catalogue — the 2012 Nissan Pulsar is fitted with a screw-on oil filler cap on the top of the cam/rocker cover. That makes the oil-cap fully relevant and required on this model.

On a 2012 Nissan Pulsar, the oil cap is the simple but crucial bit that seals the engine’s oil filling point. It keeps dust and moisture out, helps maintain correct crankcase ventilation, and stops oil mist from escaping. It’s also the point where fresh oil is poured in during a service. Because the Pulsar’s MR-series petrol engines rely on a tight crankcase seal to keep things clean and efficient, a healthy oil cap (and its rubber seal) really matters.

During regular servicing — typically every 10,000 km or 12 months in Australia and New Zealand, or as per the schedule that matches local conditions — the oil cap deserves a quick once-over. The tech will wipe the threads and seating face, check the rubber gasket for hardening or cracks, and make sure the cap spins on smoothly and seats firmly by hand. There’s no need for tools
