Parts for your 2016 Nissan Pathfinder-Manifold gasket

2016 Nissan Pathfinder manifold-gasket — purpose, service tips, and when to replace

Per Nissan’s own technical publications for the R52-series Pathfinder (2016 model year) — notably the Electronic Service Manual (ESM) sections covering Engine Mechanical (intake manifold) and Exhaust (manifolds), along with the Nissan Electronic Parts Catalogue (EPC/FAST) — this vehicle is fitted with both intake manifold gaskets and exhaust manifold gaskets. So a manifold-gasket is absolutely relevant to the 2016 Nissan Pathfinder (VQ35DE petrol V6, and applicable hybrid variants).

On a 2016 Pathfinder, manifold gaskets seal two critical junctions. Up top, the intake manifold gaskets (moulded rubber or composite seals) keep unmetered air out, so the engine breathes exactly what the ECU expects. Downstream, multi-layer steel exhaust manifold gaskets seal hot gases as they leave the cylinder heads and head into the manifold/catalyst assemblies. The Nissan ESM details correct removal/installation sequences and torque values for these joints, and the EPC lists the corresponding gasket part numbers, reinforcing that they’re designed as serviceable items.

They’re not a routine “replace by kilometres” consumable, but they are replaced any time the manifold comes off, or if there are symptoms of a leak. Typical intake leak signs include a whistling or hissing noise, rough idle, lean codes (like P0171/P0174), and a slight drop in fuel economy. Exhaust leaks often show as a ticking sound on cold start, sooty marks near the flange, faint exhaust smell in the engine bay, or O2 sensor fuel trim oddities.

Best practice is to use quality OEM-equivalent gaskets, clean both mating surfaces properly, and follow the ESM torque specs and tightening sequence — especially important on the VQ35DE’s composite intake collector and the hot, expanding exhaust joints. Reusing crushed exhaust gaskets is a false economy
