Parts for your 2014 Holden Commodore-Exhaust gasket

2014 Holden Commodore exhaust-gasket — what it does and when to sort it

Yes, an exhaust-gasket is absolutely used on the 2014 Holden Commodore. Factory documentation backs this: the GM Holden VF Service Manual (Engine Exhaust section) specifies gaskets at the exhaust manifold-to-cylinder head and at various flanged joints, and the Holden/GM parts catalogue lists dedicated exhaust manifold gaskets and pipe flange/donut gaskets for the VF V6 and V8. Reputable parts catalogues (ACDelco, Permaseal, Mahle, Fel‑Pro) also list direct-fit exhaust-gaskets for 2014 Commodore engines (LFW/LFX V6 and L77 V8), confirming their relevance on this model.

The exhaust-gasket’s main job is simple but vital: keep hot exhaust gases sealed inside the system from the head, through the manifolds and cats, and down to the rear mufflers. A healthy gasket prevents that annoying ticking on cold start, stops fumes sneaking into the cabin, protects nearby components from heat, and keeps O2 sensor readings stable so fuel trims don’t go haywire. On the VF, the manifold gaskets are typically multi‑layer steel for durability, while intermediate joints use flat or ring/donut gaskets depending on the flange design.

When servicing a 2014 Commodore, it’s smart to replace exhaust-gaskets any time a joint is disturbed. While GM often allows re-use of undamaged multi-layer steel manifold gaskets (especially on the L77 V8), most techs prefer fresh gaskets to avoid comebacks. Always follow the service manual torque values and sequence for the manifold bolts, check manifold and head surfaces for warping, and use new hardware where specified. For flange or donut gaskets, replacement on refit is best practice. No sealants unless the manual explicitly calls for it.

• Common signs a gasket’s on the way out:
  • Ticking/rasping on start-up that softens as it warms
  • Sooty marks around a flange or manifold face
  • Exhaust smell near the engine bay or underfloor
  • Slight loss of low-end torque, worse fuel use, or odd O2 trim behaviour

Handy workshop tips: soak fasteners with penetrating oil beforehand, support the exhaust so you’re not loading the studs, clean mating faces to bare metal with a Scotch-Brite pad, and recheck for leaks after the first heat cycle. Done right, a quality exhaust-gasket will go the distance on Aussie and Kiwi roads alike.

Popular questions about 2014 Holden Commodore exhaust-gasket

Does a 2014 Holden Commodore actually have an exhaust-gasket?
Yes. The VF Service Manual specifies manifold and flange gaskets, the Holden/GM EPC lists them by part, and major gasket brands catalogue direct-fit options for the VF’s V6 and L77 V8. They’re part of the standard exhaust sealing setup from factory.

How much does an exhaust-gasket job cost on a VF?
Parts are usually affordable: flange/donut gaskets from roughly $20–$60 each and manifold gaskets often $40–$120 per bank, depending on brand. Labour ranges widely: 0.5–1.0 hr for a simple flange gasket, up to 2–3 hrs per side on a V8 manifold if studs are stubborn. Pricing varies by workshop and condition of hardware.

Can the existing manifold gaskets be reused?
Sometimes. The VF’s multi-layer steel manifold gaskets can be reused if they’re undamaged and seal surfaces are mint. That said, many techs fit new ones as cheap insurance, and flange/donut gaskets should be replaced whenever the joint is opened to prevent leaks.
