Parts for your 2009 Ford Falcon-Exhaust gasket

2009 Ford Falcon exhaust gasket — what it is and how to look after it

Yes, the 2009 Ford Falcon (FG series) uses exhaust gaskets. This is confirmed by the Ford FG Falcon Workshop Manual procedures for removing/refitting the exhaust manifold and front pipe (which specify discarding and replacing the manifold and flange gaskets), the Ford Australia Electronic Parts Catalogue (EPC) listings for FG exhaust manifold and flange/donut gaskets for the 4.0L I6 and applicable V8 variants, and local gasket catalogues from brands like Permaseal and ACL that list manifold and flange gaskets for FG models. So it’s absolutely a relevant service item on this Falcon.

The exhaust gasket’s job is to seal the high‑temperature joint between the exhaust manifold and the cylinder head, and at various flanges further down the system. That tight seal keeps hot gases inside the pipes, stops that annoying ticking on cold start, prevents exhaust fumes creeping into the cabin, and helps the oxygen sensors read cleanly so the engine management doesn’t go rich and chew through fuel. On turbo XR6 models, proper sealing also protects spool and keeps boost control tidy.

There’s no fixed replacement interval, but gaskets should be replaced any time the manifold, turbo, cat or front pipe is removed, or if there are signs of a leak. During regular servicing, a quick listen and look around the manifold and front flange is smart practice. If the Falcon lives a hard life towing, copping lots of heat cycles, or has been tuned, inspections matter even more.

Signs it’s time for attention can include:

• A sharp ticking or puffing noise on cold start that softens as it warms
• Soot marks around the manifold or flange joints
• Exhaust smell under the bonnet or near the firewall
• Sluggish response, odd fuel trims, or O2 sensor fault codes

When replacing, clean the mating faces properly, use quality new gaskets (manifold-to-head is typically a multi-layer steel gasket
