Parts for your 2016 Nissan Pathfinder-Exhaust gasket

2016 Nissan Pathfinder exhaust-gasket

Based on the Nissan R52 Pathfinder Service Manual (2016) — Sections EX (Exhaust System) and EM (Engine Mechanical) — and the Nissan Electronic Parts Catalogue for the VQ35DE model, the 2016 Nissan Pathfinder is fitted with multiple exhaust-gaskets. These include the multi-layer steel exhaust manifold gaskets (cylinder head to manifold) and crush-type “donut”/ring gaskets at the front exhaust tube and other flanged joints. The factory guidance designates these gaskets as replace-after-removal items to ensure a gas-tight seal.

On this model, the exhaust-gasket’s job is to seal each joint in the exhaust stream so hot gases flow through the pipes and the catalytic converters — not out into the engine bay or underbody. A proper seal keeps the Pathfinder quiet, protects occupants from fumes, and maintains correct oxygen sensor readings for good fuel economy and emissions. At the manifold, a multi-layer steel gasket copes with extreme heat and expansion, further downstream, crush-type gaskets conform to minor flange irregularities and clamp up tightly.

There’s no fixed replacement interval for exhaust-gaskets on the 2016 Pathfinder. Instead, they’re renewed whenever the joint is disturbed (for example, when removing the manifold, catalytic converter, or front pipe), or if there’s evidence of a leak. Best practice is to use quality OEM-spec gaskets, clean both sealing faces, avoid sealants on metal or crush-type gaskets unless the service manual explicitly allows it, and tighten fasteners in the specified sequence and torque. Corroded studs and nuts should be replaced, and heat shields refitted. After any exhaust work, it’s smart to do a quick cold-start check and a short road test to confirm the seal.

Common signs of a tired or blown exhaust-gasket on a 2016 Pathfinder include:

• A sharp ticking or pff-pff sound on cold start that softens as it warms up
• Sooty marks around a flange or manifold area, or a whiff of exhaust under the bonnet
• Harsher exhaust note, slight loss of low-down torque, or fuel trims/O2 codes from false air

For owners in Australia and New Zealand, fixing leaks quickly helps avoid noise defects, keeps the vehicle tidy for WOF/RWC checks, and prevents heat damage to nearby components.

Popular questions

Does a 2016 Nissan Pathfinder use an exhaust-gasket?
Yes. The R52 Pathfinder with the VQ35DE engine uses exhaust manifold gaskets at the cylinder heads and crush/“donut” gaskets at the front exhaust tube and other flange joints. Nissan service documentation specifies replacing these gaskets whenever the joint is undone to maintain a proper seal.

How long do the exhaust-gaskets last on a 2016 Pathfinder?
They can last many years if the joint isn’t disturbed. Heat cycling, corrosion (especially near the coast), or a bumped exhaust can shorten their life. If components are removed, plan on new gaskets during reassembly. At regular services, a quick listen on cold start and a visual check for soot trails is worthwhile.

Is it okay to drive with a leaking exhaust-gasket?
It’s not recommended. A leak can allow fumes into the cabin, increase noise, and skew oxygen sensor readings, which can affect fuel economy and emissions. It may also lead to failed WOF/RWC inspections. Have the leak diagnosed and the correct gasket fitted promptly.
