Parts for your 2007 Holden Captiva 5-Exhaust gasket

2007 Holden Captiva 5 – Exhaust Gasket

Based on the Holden CG Captiva Workshop Manual (GM Service Information, 2006–2011), the Opel Antara service data (the Captiva 5’s twin), and major gasket catalogues from Permaseal and Fel‑Pro, the 2007 Holden Captiva 5 is fitted with exhaust gaskets. There’s a multi‑layer steel exhaust manifold gasket between the cylinder head and manifold, and at least one flange or “donut” style gasket/seal at the front pipe–catalyst or manifold joint, depending on engine variant. So yes—an exhaust gasket is absolutely relevant on this model.

On this Captiva 5, the exhaust gasket’s job is to keep hot gases sealed inside the exhaust stream from the moment they leave the head. That airtight seal keeps things quiet, protects nearby components from heat, and—importantly—prevents false readings at the oxygen sensors that can mess with fuelling and economy. It also stops fumes finding their way into the cabin and helps the engine maintain proper back‑pressure for smooth drivability.

While exhaust gaskets aren’t a routine “replace every service” item, they’re consumables once disturbed or if there’s any hint of leakage. A skilled tech will check for tell‑tales during servicing: a sharp ticking on cold start that softens warm, sooty marks around the manifold or flanges, a whiff of exhaust under the bonnet, or trim rings and studs showing heat stress. Modern MLS manifold gaskets should be installed clean and dry—no goos—using the factory torque and sequence to avoid warping the manifold. If the front pipe uses a crush ring, it should be renewed any time that joint is separated. Hardware that’s pitted or stretched gets binned and replaced.

• When to replace: after any manifold-off work, if there’s a leak, or when studs/nuts are renewed.
• Common symptoms: ticking noise, exhaust smell, visible soot, rough idle, lean codes after the O2 sensor gets confused.
• Good practice: inspect manifold flatness, chase threads, fit new studs/nuts, and recheck torque after a couple of heat cycles.

Owners in Australia and New Zealand will find parts readily available by VIN—both the manifold gasket and the front flange/donut seal are catalogued for CG‑series Captiva 5 models. A tidy seal keeps the Captiva quiet, efficient, and compliant for roadworthy/WOF checks.

FAQs

Does the 2007 Captiva 5 use a manifold gasket or a donut gasket?

It uses both. There’s a dedicated exhaust manifold gasket at the head, and a flange or crush‑ring (“donut”) gasket at the front pipe/catalyst junction on most variants. Parts are listed in Holden CG Captiva service data and major gasket catalogues.

Is it safe to drive with a leaking exhaust gasket?

Not ideal. A small leak can quickly get louder, skew O2 sensor readings, and push fumes under the bonnet and near the cabin intake. It can also lead to a WOF/roadworthy fail for noise or emissions. Best to repair promptly.

What does replacement typically cost and how long does it take?

In AU/NZ workshops, a manifold gasket job typically runs 1.5–3.0 hours plus parts, depending on engine and stud condition. Donut/flange seals are quicker. Corroded hardware can add time, so allowing for new studs and nuts is smart.
