Parts for your 2016 Nissan Pulsar-Exhaust gasket

2016 Nissan Pulsar exhaust gasket: what it does and when to replace it

Yes, the 2016 Nissan Pulsar uses exhaust gaskets. Nissan’s 2016 Electronic Service Manual (ESM) for the B17/C12 Pulsar platform (EX – Exhaust System) lists an exhaust manifold gasket at the cylinder head and flange/donut gaskets at the front pipe and muffler joints. The Nissan FAST/Global parts catalogue also shows these sealing rings and flanged gaskets across the 2016 Pulsar range. Equivalent documentation for the near-identical 2016 Sentra (B17) confirms the same gasket locations and service approach.

On a 2016 Pulsar, the exhaust gaskets keep the system sealed from the engine to the tailpipe. The manifold gasket (usually a multi-layer steel style) seals the join between the cylinder head and manifold, stopping hot gases from escaping under the bonnet and keeping oxygen sensor readings on the money. Further back, a crush-style “donut” ring and flat flange gaskets seal the front pipe, cat and muffler sections, cutting noise, fumes and soot while helping the engine breathe properly.

There’s no set replacement interval in the factory schedule, but it’s smart to inspect gaskets at service time, especially if the car has copped a knock, done heaps of kilometres, or any exhaust bits have been removed. Typical clues a gasket’s on the way out include a ticking noise on cold start that softens as it warms up, a whiff of exhaust in the cabin, black soot around a joint, or a check-engine light from skewed O2 readings.

If a joint is disturbed, fit a new gasket—reusing the old one is false economy. Clean the mating faces, check studs and springs, and use fresh hardware where needed. Don’t smear sealant on exhaust gaskets
