Parts for your 2013 Nissan Pathfinder-Manifold gasket

2013 Nissan Pathfinder manifold gasket — purpose and service tips

Based on Nissan technical sources, a manifold gasket is definitely used on the 2013 Nissan Pathfinder (R52). The Factory Service Manual for the R52 Pathfinder (Engine Mechanical and Exhaust sections) specifies intake manifold gaskets and exhaust manifold gaskets for the VQ35DE 3.5‑litre V6, and the Nissan parts catalogue lists genuine replacement gaskets for both locations. So, the manifold-gasket is relevant to this model and is a normal wear-and-seal component whenever the intake or exhaust manifolds are removed or when leaks are diagnosed.

On this Pathfinder, the intake manifold gasket seals the junction between the intake manifold and the cylinder heads, keeping unmetered air out so the engine management can control fuel trims properly. A tight seal helps cold starts, smooth idle, decent fuel economy and keeps the check-engine light at bay. The exhaust manifold gasket, on the other hand, keeps hot exhaust gases from escaping before they reach the catalytic converters and oxygen sensors. That protects nearby components, reduces noise, avoids exhaust odours under the bonnet or in the cabin, and keeps O2 readings accurate for correct fueling.

There’s no fixed kilometre-based replacement interval for these gaskets, they’re replaced when disturbed or when symptoms show up. Common signs include a ticking or puffing noise on cold start (exhaust), a hissing or whistling under light throttle (intake), rough idle, lean or rich fault codes, a drop in fuel economy, or an exhaust smell. Any time the intake is lifted—say for spark plug or plenum work—new intake manifold gaskets should go in. The exhaust side often uses crush-style gaskets that should be renewed once removed. After refitting, correct torque and sequence are essential to avoid warping or fresh leaks.

• Use quality OEM-spec gaskets, avoid generic sealants unless the service manual specifically calls for a small bead in certain joints.
• Clean mating surfaces carefully and check for flatness, replace any rusty or stretched manifold studs/nuts.
• After installation, run a quick smoke test (intake) or soapy water test (exhaust, cold) to confirm no leaks.
• Keeping the PCV system healthy and fixing misfires promptly helps extend gasket life by reducing crankcase pressure and exhaust heat spikes.

Popular questions about the 2013 Nissan Pathfinder manifold gasket

Does the 2013 Pathfinder have intake and exhaust manifold gaskets?
Yes. The R52 Pathfinder with the VQ35DE uses gaskets at the intake manifold-to-head interfaces and at the exhaust manifold-to-head joints. This is outlined in Nissan’s Factory Service Manual (Engine Mechanical and Exhaust sections) and reflected in the Nissan parts catalogue for this model.

What are the tell-tale signs a manifold gasket is failing?
Owners often notice a ticking or chuffing sound at the front of the engine on cold start (exhaust leak), or a hiss/whistle and a rough idle (intake leak). Other signs include a fuel economy drop, exhaust odour, visible soot near the manifold, or lean/rich and O2 sensor-related fault codes.

Should sealant be used when installing a new manifold gasket?
Generally, no. The OEM gasket is designed to seal dry. Only use sealant where the Nissan service manual specifically calls for it. Always follow the torque specs and sequence, refit new crush gaskets on the exhaust, and recheck for leaks after the first heat cycle.
