Parts for your 2017 Nissan Serena-Manifold gasket

2017 Nissan Serena manifold gasket: what it does and when to sort it

Yes, the 2017 Nissan Serena (C27 series) uses manifold gaskets. Both the intake manifold and the exhaust manifold are sealed to the cylinder head with dedicated gaskets on the MR20DD 2.0-litre S-HYBRID, and on the e-POWER variant’s petrol engine as well. This is documented in the Nissan Serena C27 Service Manual (Engine Mechanical section) for removal/installation procedures, and in the Nissan Electronic Parts Catalog (FAST) for C27/HC27/GC27, which lists the intake and exhaust manifold gaskets as service parts. Genuine parts catalogues widely used by workshops also show these gaskets for the C27 platform.

A manifold gasket is a simple but critical seal. On the intake side, it prevents unmetered air sneaking into the engine, which would otherwise throw out fuel trims, cause rough idle, hesitation, or a lean code. On the exhaust side, it keeps hot gases in the manifold so the O₂ sensors read correctly and the cabin doesn’t cop fumes or that tell-tale ticking on cold start. Materials vary (multi-layer steel, graphite, composite), but all live a hard life with heat cycles, vibration, and the odd splash of oil or coolant that can shorten their days.

There’s no set replacement interval, but they should be inspected any time the manifold is off (for example, carbon clean, injector or EGR work). If a Serena’s showing these signs, a gasket check is well worth it:

• Sharp ticking from the engine bay on cold start (often eases warm), whiff of exhaust under the bonnet, or black soot at the flange
• Hunting/rough idle, lean codes, or a hiss that changes when spraying around the intake joint

Good practice when replacing: use new gaskets (don’t reuse crushed ones), clean mating faces, and follow the factory torque and sequence. The Serena’s manifolds use specific tightening orders to avoid warping, this is laid out in the C27 service manual. Check studs and nuts for corrosion, ensure heat shields are refitted, and only use sealant where Nissan specifies it. For the e-POWER engine, even though it runs mostly as a generator, the exhaust gasket still sees repeated heat cycles, so the same care applies.

As part of routine servicing on a 2017 Serena, a quick visual for soot tracks, a listen for ticks or hisses, and a scan for fuel-trim anomalies can catch gasket issues early. If a manifold’s coming off for any reason, budget in fresh gaskets—it’s cheap insurance against do-overs and annoying leaks.

Does the 2017 Serena have separate intake and exhaust manifold gaskets?
It does. The C27 platform uses an intake manifold gasket between the intake runner assembly and the head, and an exhaust manifold gasket between the exhaust manifold and the head. Both are standard service items listed in Nissan’s C27 service literature and parts catalogues.

What are common symptoms of a blown manifold gasket on a C27 Serena?
Exhaust side: a ticking noise on cold start, exhaust odour around the engine bay, soot at the manifold flange, or skewed O₂ sensor readings. Intake side: rough or high idle, lean fault codes, hesitation, or a noticeable hiss that changes when sprayed with brake cleaner around the joint.

Should the manifold gasket be replaced proactively during other work?
If a manifold is removed, yes—fit new gaskets. They’re designed to crush once and may not reseal properly when reused. Follow the Nissan torque specs and tightening sequence, and inspect studs, nuts, and shield hardware while you’re there.
