Parts for your 2002 Daihatsu Yrv-Manifold gasket

2002 Daihatsu YRV manifold gasket — fitment, purpose and service tips

Based on the Daihatsu YRV M200-series Workshop Manual (Engine Mechanical section) and the Daihatsu Electronic Parts Catalogue, the 2002 YRV (K3-VE 1.3 and K3-VET 1.3 turbo) uses both an intake manifold gasket and an exhaust manifold gasket between the cylinder head and the respective manifolds. Major gasket manufacturers’ catalogues (e.g., Victor Reinz, Elring, Ajusa) also list these parts specifically for the YRV, confirming they’re standard fitment on this model.

The manifold gasket’s job is straightforward but critical. On the intake side it seals the path between the head and intake manifold, keeping unmetered air out so the engine maintains the right air–fuel mix, smooth idle, and decent fuel economy. On the exhaust side it keeps hot gases heading into the turbo (on K3-VET) or straight to the cat, preventing leaks, ticking noises, fumes under the bonnet, and oxygen-sensor confusion. Materials vary from fibre/composite and graphite to multi-layer steel (MLS), all designed to handle heat cycles, vibration, and slight surface imperfections.

As part of routine servicing on a 2002 Daihatsu YRV, it’s worth a quick check for tell-tale signs of gasket trouble:

• Exhaust tick on cold start, soot marks at the manifold flange, or whiffs of exhaust in the cabin/engine bay.
• Rough idle, lean codes, or a whooshing hiss around the intake side.
• Higher fuel use, sluggish performance, or boost loss on the turbo K3-VET.

If replacement’s on the cards, a bit of care goes a long way. Let it cool fully, soak fasteners with penetrant, and avoid snapping studs. Clean the mating faces gently (no gouging) and check the manifold with a straightedge for warpage or cracks—common on hard-worked turbo setups. Always fit new gaskets
