Parts for your 2017 Nissan Pathfinder-Exhaust gasket

2017 Nissan Pathfinder exhaust gasket

Technical sources confirm the 2017 Nissan Pathfinder does use exhaust gaskets. The Nissan Pathfinder R52 (2017) Factory Service Manual (sections EXH – Exhaust System and EM – Engine Mechanical) shows gaskets at the exhaust manifold-to-cylinder head and at pipe/flange joints, including crush “donut” gaskets on the front tube connections. Nissan parts catalogues for the R52/VQ35DE also list exhaust manifold gaskets and front/rear pipe flange gaskets. So an exhaust gasket is fitted and is absolutely relevant to this model.

On the 2017 Pathfinder, the exhaust gasket’s job is simple but critical: it seals the joins where hot gases leave the engine and move through the exhaust. That tight seal keeps fumes out of the cabin, stops the tell‑tale ticking of leaks, and helps the oxygen sensors and catalytic converters do their thing properly for smooth running and good fuel economy.

This model uses multi‑layer steel manifold gaskets at the cylinder heads and crush-type (donut) and flat flange gaskets further down the system. Over time, heat cycles, road grime, and a bit of coastal life can harden or crush these gaskets. When they leak, you might notice a sharp ticking on cold start, a whiff of exhaust around the engine bay, sooty marks near a joint, or even a check engine light from wonky sensor readings.

Replacement is straightforward workshop fare and best done any time the manifold or front pipes are removed. Always fit new gaskets—reusing old ones usually ends in another leak. Clean the mating faces, check flanges for warping, and replace tired studs, springs and nuts where used. Follow the Factory Service Manual for torque values and tightening sequence, especially on the manifold, uneven clamping can warp parts and shorten gasket life.

• Symptoms to watch: ticking at start-up, exhaust smell, visible soot at joints, rattly spring bolts, and poor fuel economy.
• Good practice: inspect during scheduled services, especially after off‑road work, towing, or a scrape underneath, use quality OEM‑spec gaskets, avoid generic sealants unless rated for exhaust temperatures and specified by the manual.
• Safety first: if fumes are noticeable, park it and sort the leak—carbon monoxide isn’t something to muck around with.

Look after the gaskets and hardware, and the Pathfinder’s V6 will stay quiet, efficient, and ready for the next long haul.

Popular questions about 2017 Nissan Pathfinder exhaust gaskets

Does the 2017 Pathfinder use both manifold and donut gaskets?

Yes. It uses manifold-to-cylinder head gaskets at each bank and crush (donut) gaskets on spring‑bolted front tube joints, plus flat flange gaskets further back. This layout is detailed in the Factory Service Manual’s EXH section and parts listings for the R52.

How often should exhaust gaskets be replaced on a 2017 Pathfinder?

There’s no fixed interval—they’re replaced when removed or when leaking. Have them inspected at regular services, after any underbody knock, or if there’s a ticking noise or exhaust smell. Any time the manifold or front pipe is off, fit new gaskets as a matter of course.

Is it safe to drive with a leaking exhaust gasket?

Not ideal. Aside from fumes, leaks can skew oxygen sensor readings and stress the catalytic converters. Short trips to a workshop are usually fine, but it’s best to get it sealed promptly.
