Parts for your 2014 Nissan Pathfinder-Manifold gasket

2014 Nissan Pathfinder manifold-gasket: what it does, when it fails, and how to look after it

Yes, the 2014 Nissan Pathfinder is fitted with manifold-gaskets. This applies to both the V6 (VQ35DE) and the Hybrid (QR25DER) models. Technical references include the Nissan Pathfinder (R52) Factory Service Manual—EM: Engine Mechanical (Intake Manifold) and EXH: Exhaust System—plus Nissan’s Electronic Parts Catalog (FAST) and dealer parts catalogues, all of which list intake manifold gaskets and exhaust manifold gaskets for this model. Major aftermarket catalogues (e.g., Fel‑Pro) also catalogue both intake and exhaust manifold-gaskets for the 2014 Pathfinder, confirming their use.

The manifold-gasket is a sealing hero that stops air or exhaust leaks where the manifold bolts to the engine. On the intake side, it keeps unmetered air out so the engine runs smoothly and the fuel trims stay happy. On the exhaust side, it keeps hot gases inside the manifold on their way to the catalytic converters, reducing noise, fumes, and protecting nearby components from heat.

For servicing a 2014 Pathfinder, manifold-gaskets aren’t a routine replacement item, they’re replaced when the manifold comes off or when there’s a leak. Still, a quick check during a scheduled service pays off. A tech can do a visual once‑over and a quick listen under the bonnet—especially on cold start.

• Common intake leak clues: rough idle, a hissing sound, higher long‑term fuel trims, lean fault codes, or a flat spot off idle.
• Common exhaust leak clues: ticking on cold start that softens as it warms, sooty marks at the flange, exhaust odour in the cabin, or increased noise.

When replacing a manifold-gasket, use quality OEM or reputable aftermarket parts and follow the Nissan torque sequence and specs. Clean the mating faces carefully, avoid gouging aluminium surfaces, and never double‑up old gaskets. On the intake, replace related O‑rings and the throttle body gasket if disturbed, and consider an Idle Air Volume Learn if the throttle body has been off. On the exhaust side, heat and corrosion can seize studs—so budget time for careful removal and new hardware. Refit heat shields and check nearby looms and hoses for heat damage.

Whether it’s the V6 or the Hybrid, a fresh, correctly installed manifold-gasket keeps the Pathfinder quiet, efficient, and compliant—no dramas, no fumes, and better fuel economy on those long Kiwi and Aussie kilometres.

Popular questions about 2014 Nissan Pathfinder manifold-gasket

Do all 2014 Pathfinders have manifold-gaskets?
They do. Both the V6 and the Hybrid variants use intake and exhaust manifold-gaskets, as confirmed by the Nissan R52 Factory Service Manual and Nissan’s parts catalogue listings.

What are the tell‑tale signs of a leaking manifold-gasket?
Intake leaks often show up as a rough or high idle, a hissing noise, or lean codes. Exhaust leaks usually sound like a ticking on cold start, may leave sooty traces near the flange, and can bring exhaust odour into the cabin.

Should RTV sealant be used on a manifold-gasket?
Generally, no. Follow Nissan’s procedures: the gaskets are designed to seal without extra sealant. Only use sealant where the service manual explicitly specifies, and never on surfaces that could shed material into the engine or exhaust.
