Parts for your 2016 Subaru Xv-Manifold gasket

2016 Subaru XV manifold gasket — what it does and how to look after it

Technical sources confirm the 2016 Subaru XV is fitted with manifold gaskets. The Subaru FB20 Engine Service Manual for MY2016 XV/Crosstrek (STIS, Engine Mechanical: Intake Manifold and Exhaust Manifold sections) specifies gaskets between the intake manifold and cylinder heads, and multi‑layer steel gaskets between the exhaust manifold and the heads. The Subaru Genuine Parts Catalogue for MY2016 XV (Intake group 14, Exhaust group 44) also lists these gaskets as required parts during removal and installation. So yes, a manifold gasket is very much used on this model.

On the XV, the intake manifold gaskets keep unmetered air out, so the engine only breathes through the airflow meter as intended. That helps maintain smooth idle, proper fuel trims, and decent economy. The exhaust manifold gaskets seal hot gases as they leave the heads, preventing ticking noises, fumes under the bonnet, and protecting nearby components from heat and soot.

They’re not a routine replacement item by time or kilometres, but they’re considered single‑use whenever the manifold is removed. During servicing or any intake/exhaust work, a tech will inspect for telltale signs like carbon staining, hiss or tick noises (especially on cold start), a whiff of exhaust odour, rough idle, or lean codes. If the manifold’s coming off for other jobs—spark plugs, rocker cover work, or cat/downpipe repairs—fresh gaskets are installed as a matter of course.

Best practice on the 2016 XV includes:

• Use OEM or equivalent-quality gaskets for the FB20 engine.
• Clean mating surfaces carefully—no gouging the alloy heads.
• Follow the factory torque sequence and values from the FB20 Engine Mechanical manual.
• Replace corroded studs/nuts and check heat shields while you’re there.
• For intake work, consider a new throttle body gasket and inspect PCV hoses and manifold boots.

After replacement, a quick smoke test helps confirm the intake side is airtight, and a listen/visual check when cold will pick up any exhaust leaks. Look after these simple seals and the XV will idle cleaner, run quieter and keep the check engine light at bay.

Does the 2016 Subaru XV have both intake and exhaust manifold gaskets?

Yes. The FB20 Engine Service Manual (MY2016 XV/Crosstrek, STIS) outlines gaskets for the intake-to-head and exhaust-to-head joints, and the Subaru electronic parts catalogue lists them in the Intake (Grp 14) and Exhaust (Grp 44) sections.

How often should manifold gaskets be replaced on a 2016 XV?

There’s no fixed interval. They’re replaced if leaking or any time the intake or exhaust manifold is removed. Many last well past 150,000 km if undisturbed, but heat cycles and age can harden them over time.

Is it safe to drive with a leaking manifold gasket?

Not ideal. Intake leaks can cause lean running and misfires, exhaust leaks can allow fumes into the cabin, skew oxygen sensor readings, and risk catalyst damage. It’s best to get it checked and sealed properly.
