Parts for your 2014 Subaru Xv-Exhaust gasket

2014 Subaru XV exhaust gasket – what it is, where it lives, and when to sort it

Based on the Subaru Factory Service Manual for the 2014 XV (GP chassis, FB20 engine) and the Subaru OEM parts catalogue (FAST/EPC for GP/GJ platform), the 2014 Subaru XV absolutely uses exhaust gaskets. These sources specify multiple sealing points in the XV’s exhaust system that rely on dedicated gaskets, including the cylinder head–to–exhaust manifold gaskets, a spring-bolt “donut” gasket at the front pipe joint, and flat/flange gaskets further rear. So, exhaust gaskets are very much relevant and fitted on this model.

The exhaust gaskets on a 2014 XV do the quiet, dirty work: they seal super-hot exhaust gases so there’s no hissing, ticking, or fumes sneaking out at the joins. Good sealing keeps the oxygen sensors reading accurately, helps the catalytic converter do its job, keeps the cabin free of exhaust whiffs, and stops that annoying drone or rasp under load.

• Cylinder head to exhaust manifold: typically a multi-layer steel gasket on each bank to lock in the seal at the heads.
• Front pipe to manifold/header: a compressible “donut” gasket with spring-loaded bolts to maintain tension through heat cycles.
• Mid-pipe and muffler flanges: flat ring gaskets to prevent leaks at the rear sections.

There’s no strict service interval for exhaust gaskets, but they’re commonly replaced any time a joint is disturbed. During regular servicing (every 12 months/15,000 km is a handy cadence), a quick visual and audible check on the hoist is wise. Leaks tend to show up as soot marks around flanges, a sharp ticking on cold start, a sulphur/exhaust smell near the rear, or a louder note under acceleration. A visible leak can also trip a WOF/regulatory inspection.

• Replace gaskets whenever a joint is undone—don’t reuse squashed or heat-cycled gaskets.
• Use new spring bolts and nuts at the donut joint if they’re corroded
