Parts for your 1997 Daihatsu Gran move-Manifold gasket

1997 Daihatsu Gran Move manifold gasket — what it does and when to replace it

Yes, a manifold gasket is fitted to the 1997 Daihatsu Gran Move. Both the intake manifold gasket and the exhaust manifold gasket are specified for the G300-series Gran Move/Pyzar models. This is confirmed by Daihatsu workshop literature for the HC/HD family engines (Engine Mechanical section) and the Daihatsu Electronic Parts Catalogue (EPC), which list separate gaskets between the cylinder head and each manifold. Major aftermarket catalogues for this model also carry dedicated intake and exhaust manifold gaskets for 1997 production.

On this Daihatsu, the manifold gaskets seal the joins where the intake manifold feeds air-fuel mix into the head, and where the exhaust manifold carries hot gases away. A healthy seal keeps unmetered air out of the intake (so the engine idles smoothly and trims stay in check) and prevents hot exhaust escaping under the bonnet (so there’s no ticking, fumes, or cooked nearby parts). They’re small, inexpensive pieces that pull a lot of weight in day-to-day reliability.

As part of routine servicing on a 1997 Gran Move, the gasket itself isn’t a scheduled replacement item, but it should be inspected whenever the manifolds are removed for other work — think timing belt jobs, head work, or exhaust repairs. If there’s any sign of blow-by, cracking, coolant or oil staining (on intake variants with coolant galleries), or the gasket is obviously flattened or brittle, replace it rather than refitting. New gaskets are cheap insurance, and reusing old ones is a false economy.

• Common symptoms of a failing intake gasket: rough cold idle, lean codes, high fuel trims, whistling under light throttle.
• Common symptoms of a failing exhaust gasket: ticking on cold start that quietens warm, exhaust smell in the cabin, visible soot near the flange.
• Good practice: torque the manifold fasteners in the workshop manual sequence and to spec, re-check after the first proper heat cycle, and avoid overusing sealant — only apply where the manual explicitly calls for it.

If the car’s done a couple of hundred thousand kilometres, or the manifold’s been off before, budget to replace the gasket set when you’re in there. A fresh gasket, clean mating faces, and properly torqued studs and nuts will keep the little Daihatsu humming along happily across Aussie and Kiwi roads.

Popular questions about 1997 Daihatsu Gran Move manifold gaskets

How can someone tell if the exhaust manifold gasket is leaking on a 1997 Gran Move?
Listen for a sharp ticking or puffing on cold start that softens as it warms. Check for sooty marks around the manifold-to-head join and a slight exhaust smell near the firewall. If the noise changes with engine load and there’s no crack in the manifold itself, the gasket is the usual culprit.

Should the intake manifold gasket be replaced proactively?
Not strictly — it’s generally done on condition. However, if the manifold is off for other work, fitting a new gasket is smart. Age-hardened gaskets can cause vacuum leaks that lead to rough idle and lean codes, so preventative replacement saves diagnostic hassle later.

Is it safe to keep driving with a blown exhaust manifold gasket?
Short trips to the workshop are usually fine, but it’s not ideal. Hot gases can damage nearby wiring and plastic, oxygen sensor readings can skew, and fumes can enter the cabin. It’s best to book a repair sooner rather than later.
