Parts for your 1998 Ford Falcon-Exhaust gasket

1998 Ford Falcon Exhaust Gasket

Based on Ford’s AU Series workshop literature and common repair manuals used in Australia and New Zealand (e.g., Gregory’s/Max Ellery), plus parts catalogues from Ford’s EPC and major gasket makers (Permaseal, ACL, Fel-Pro), the 1998 Ford Falcon (EL late and AU Series I) uses exhaust gaskets. These include a manifold-to-cylinder-head gasket and flange or “donut” gaskets at key pipe joins. So the exhaust gasket is absolutely relevant and fitted on this model.

On a 1998 Ford Falcon, the exhaust gasket’s job is straightforward: keep hot gases sealed as they exit the engine and move through the exhaust. At the manifold-to-head face it prevents leaks that can cause that tell-tale ticking on cold start, fumes under the bonnet, and skewed oxygen sensor readings. Downstream, flange or donut gaskets help keep the system quiet and stop soot streaks, pinging noises, and whiffs of exhaust making their way into the cabin.

As part of regular servicing, it’s smart to give the exhaust a once-over. A technician will look for black soot marks around the manifold and flanges, listen for chuffs or ticks, and check for any loosened fasteners or warped heat shields. If the manifold’s been off before, or if the system has had a hard life towing or doing heaps of hot/cold cycles, the gasket can go brittle or crush down and lose clamping force. Replacement is the fix—these gaskets are not a permanent, lifetime item.

When replacing, the Falcon responds best to proper prep. Surfaces should be clean and flat—no old material left behind—and studs/nuts inspected. Many techs fit new copper-coated or prevailing-torque nuts and use a dab of high-temp anti-seize on the studs. The manifold fasteners should be tightened evenly from the centre out to the workshop manual spec
