Parts for your 2016 Holden Commodore-Manifold gasket

2016 Holden Commodore manifold-gasket

Based on Holden/GM Service Information for VF Series II (MY16) and the related parts catalogues, a manifold-gasket is absolutely used on the 2016 Holden Commodore. Both the 3.6‑litre SIDI V6 and the 6.2‑litre LS3 V8 specify intake manifold-to-cylinder head gaskets and exhaust manifold gaskets in their engine mechanical sections, with removal/installation procedures that call for inspection and replacement of these gaskets. Genuine Holden/ACDelco listings also show manifold gasket sets for these engines, confirming the part is relevant and fitted from factory.

On the 2016 Holden Commodore, the manifold-gasket’s job is straightforward but critical. At the intake side, moulded rubber or O‑ring style gaskets seal the intake manifold to the heads so the engine only ingests metered air. That keeps idle stable, trims in check, and fuel economy where it should be. At the exhaust side, multi‑layer steel (MLS) gaskets seal hot gases as they leave the head, which keeps the note crisp, prevents fumes in the cabin, and protects nearby components from heat and soot. Across Aussie and Kiwi climates—stop‑start city hops, long motorway runs, and big temperature swings—these gaskets cop a lot of heat cycling, so a tight seal matters.

As part of servicing of your 2016-holden-commodore manifold-gasket, there’s no fixed kilometre interval to replace them, they’re changed when disturbed or when symptoms show up. Fresh gaskets are fitted any time the manifold comes off for other work. Day to day, the best “maintenance” is simple: keep an ear out and do a quick look‑over when the bonnet’s up.

• Common intake leak signs: a light hiss, rough or high idle, lean codes (like P0171/P0174), or a stumble on cold start.
• Common exhaust leak signs: a ticking sound on cold start that quietens warm, sooty traces near the flange, or an exhaust odour under load.

If symptoms pop up, a smoke test for the intake and a visual/soapy-water check (cold) for exhaust joints help pinpoint leaks. Replacement is straight‑forward for a trained tech: clean the mating faces, fit new gaskets, follow the factory torque sequence and specs, and don’t smear sealant unless the manual specifically calls for it. Bolts and studs should be inspected, replace anything pitted or stretched. After refit, a short road test and a scan of fuel trims will confirm the seal is mint.

For most owners, this is a workshop job. Expect labour to vary with engine and bank—intake jobs are typically quicker than exhaust manifold work tucked near the firewall. Done properly, quality gaskets will last years with no dramas.

Popular questions about the 2016 Holden Commodore manifold-gasket

Does a 2016 Holden Commodore have both intake and exhaust manifold-gaskets?
Yes. The VF Series II service procedures for the 3.6L V6 and 6.2L V8 list intake manifold-to-head gaskets and exhaust manifold gaskets. Both types are service items that are replaced if disturbed or leaking.

What are the tell‑tale signs a manifold-gasket is failing on this model?
Intake side: hissing, rough idle, lean fault codes, or a slight surge on light throttle. Exhaust side: a ticking noise on cold start, black soot marks at the joint, or an exhaust odour creeping into the cabin. If in doubt, a smoke test (intake) or careful cold inspection (exhaust) is the go.

Should the manifold-gasket be replaced as routine maintenance?
There’s no set interval. They’re replaced when the manifold is removed for other work or when leak symptoms appear. Using new quality gaskets and correct torque/sequence during refit is the key to long, leak‑free service.
