2016 Subaru XV exhaust gasket — purpose, service tips and FAQs

Technical references confirm the 2016 Subaru XV uses exhaust gaskets. The Subaru Service Manual for the GP/GP7 XV (Exhaust section) specifies replacing exhaust gaskets whenever joints are separated, and the Subaru Global EPC/FAST parts catalogue lists multiple gaskets for this model, including the “Gasket–Exhaust” donut ring (commonly referenced as 44022AA170) at pipe joints and multi‑layer steel manifold gaskets at the cylinder heads. Major aftermarket catalogues also carry these specific gaskets for the XV, making the exhaust gasket absolutely relevant on this vehicle.

On the 2016 Subaru XV, exhaust gaskets do the quiet, critical work of sealing hot gases where metal parts meet — at the manifold-to-head, and at the spring‑bolt donut and flat‑flange joints along the system. They keep the boxer’s note tidy, prevent fumes sneaking into the cabin, and help the oxygen sensors read cleanly so the engine management can keep fuel economy on point.

As part of regular servicing, exhaust joints deserve a quick look, especially on cars that see coastal air, unsealed roads or short‑trip city use. A healthy gasket shows no sooty marks, no fresh streaks, and no ticking on cold start. If the system has been apart for a clutch, gearbox or exhaust repair, new gaskets should be fitted — Subaru’s manual is clear that compressed gaskets aren’t to be reused. When replacing, support the exhaust properly, crack spring bolts evenly, and fit new hardware if corroded. Surfaces should be clean and flat, never use sealants or paste on the sealing faces, and keep oxygen sensors free of contamination. After reassembly, run the engine to temperature and check for any seep or chirp, then recheck fasteners once cooled after a heat cycle.

Typical signs a gasket’s on the way out include a sharp ticking or rasp on cold start that softens warm, a whiff of exhaust near the front of the car, soot around a joint, slight loss of torque low down, or a new drone under load. Left alone, a leak can skew O2 readings and bump fuel use. Many XVs go years without drama, but once a joint is disturbed or corrosion sets in, fresh gaskets are cheap insurance for quiet motoring and a happy WOF.

• Listen: ticking/rasp at start-up, droning under load
• Look: black soot at joints, rusted springs/bolts
• Smell: exhaust fumes near the engine bay or cabin

Popular questions about 2016 Subaru XV exhaust gaskets

What are the common symptoms of a leaking exhaust gasket on a 2016 Subaru XV?
A cold-start tick, soot around a flange, or a sharper exhaust note are the big giveaways. Some owners also notice a faint exhaust smell near the firewall or a slight drop in low‑rpm pull. If the leak is ahead of the oxygen sensor, fuel economy can slip as the ECU chases skewed readings.

How often should exhaust gaskets be replaced?
There’s no set kilometre interval. They’re replaced whenever a joint is separated or when inspection shows leaking, noise or damage. In Aussie and NZ conditions, cars near the coast or doing gravel work may need them sooner due to corrosion, garage‑kept city cars often run the originals for many years.

Is it safe to drive with a suspected exhaust gasket leak?
It’s best not to. Small leaks can allow fumes into the cabin and can upset sensor readings, which may lead to higher fuel use and catalyst stress. Short trips to a workshop are usually fine with windows cracked, but prompt repair is the smart move.
