Parts for your 2016 Holden Commodore-Exhaust gasket

2016 Holden Commodore exhaust-gasket

Based on Holden/GM technical literature, an exhaust-gasket is indeed used on the 2016 Holden Commodore (VF Series II). The GM Service Information (SI) procedures for VF exhaust manifold replacement specify manifold-to-cylinder head gaskets, and the front exhaust/collector joints use a sealing ring (often called a donut or flange gasket). GM/Holden Electronic Parts Catalogues list these gaskets for both the 3.6L V6 and 6.2L V8 variants, confirming the part is fitted and serviceable. These sources establish the exhaust-gasket is relevant on this model.

On a 2016 Holden Commodore, the exhaust-gasket’s job is simple but critical: keep hot gases sealed inside the exhaust stream from the cylinder head through to the front pipes. The manifold gaskets are typically multi-layer steel to cope with heat cycles, while the front-pipe uses a crush or ring-style gasket that allows a bit of flex without leaking. When these seals are healthy, there’s less noise, no exhaust odour in the cabin, and the oxygen sensors get clean readings so the engine management can do its thing properly.

As part of routine servicing, a quick check is smart. Look for sooty traces around the manifold-to-head area and front flanges, listen for a sharp ticking on cold start that softens as it warms up, and take note of any whiff of exhaust under the bonnet or near the firewall. A persistent leak can skew fuel trims, light the MIL, and in the worst case overheat nearby components.

Replacement rules of thumb are straightforward. If the manifold or front pipe is removed, new gaskets should go in—these are designed to crush once and aren’t worth reusing. Surfaces need to be clean and flat, no sealants are required on the MLS manifold gaskets. Follow the GM SI torque specs and sequence so the gasket beds in evenly. On the front joint, fit a new ring/donut and inspect the spring bolts and studs, replace any that are corroded or have lost tension. After the first heat cycle, a quick re-check for any noise or whiff is a good idea.

Leaving a leak to rattle on isn’t ideal. Besides the racket, exhaust gases under the bonnet are a safety risk, and prolonged leaks can lead to warped flanges or cooked plugs and wiring. Fresh gaskets are inexpensive insurance for a quiet, efficient Commodore.

• Common signs: ticking on cold start, exhaust smell, black soot at joints, MIL with lean or O2 sensor codes.
• Best practice: replace gaskets whenever disturbed, don’t add sealant, use correct torque and sequence from GM SI.

FAQs

Does a 2016 Holden Commodore have an exhaust-gasket and where is it?
Yes. There are manifold gaskets between the cylinder heads and exhaust manifolds, and a sealing ring/gasket at the front-pipe joint. Both the V6 and LS3 V8 use these seals as shown in Holden/GM service procedures and parts catalogues.

How often should the exhaust-gasket be replaced on a 2016 Commodore?
They’re not a scheduled replacement item, they’re replaced when disturbed or if there’s a leak. Any time the manifold or front pipe comes off, fit new gaskets. If there’s ticking, soot, or exhaust smell, plan a replacement sooner rather than later.

Is it safe to drive with a leaking exhaust-gasket on a VF Commodore?
Short trips might be possible, but it isn’t recommended. Leaks can let fumes into the cabin, trigger engine codes, and potentially damage nearby components. It’s best to repair promptly.
