2013 Honda Elysion Oil Cap

Technical references including the Honda Elysion owner’s manual (2012–2013 JDM/China editions, Engine Oil section), the Honda service manuals for K24A/J-series engines, and Honda’s Electronic Parts Catalogue all specify an engine oil filler cap on the valve/rocker cover. So yes—the 2013 Honda Elysion is fitted with an oil cap, and it’s a relevant, serviceable part.

The oil cap on a 2013 Honda Elysion seals the top of the engine where oil is added, keeping dust and moisture out and crankcase vapours and oil mist in. On K-series 2.4-litre engines it sits prominently on the cam cover, on J-series V6 models it’s on the front bank’s rocker cover under the bonnet. A healthy cap and seal help maintain correct crankcase pressure and prevent oil weep, smells in the cabin, and messy engine bays.

As part of routine servicing, the oil cap deserves a quick once-over each time the oil’s changed. Honda’s factory guidance for these engines expects owners or technicians to refit the cap by hand until it seats firmly—no tools needed. If the cap cross-threads, won’t tighten, or its rubber seal has gone hard, cracked, or flattened, it’s time to replace it. The Honda EPC lists a dedicated cap assembly for both K24 and J-series applications, and genuine or quality OEM-equivalent parts are recommended so the seal material and thread profile match the original.

Common signs an Elysion’s oil cap needs attention include:

• Oil misting or wetness around the filler neck after driving
• A perished, swollen, or missing rubber seal/gasket
• Cap that feels loose, doesn’t seat squarely, or has damaged tabs
• Burnt-oil odour under the bonnet

Left unfixed, a poor seal can let unfiltered air and moisture in and allow oil vapour out—bad for emissions, tidy engine bays, and potentially for long-term engine health. During each service (typically every 10,000 km or 12 months in AU/NZ conditions, or per the owner’s manual), they should:

1. Wipe the filler neck and cap clean to keep grit away from the engine
2. Inspect the rubber seal and replace the cap if the seal is tired
3. Refit the cap hand-tight until snug, don’t overtighten

If the cap is lost or broken, avoid driving. Oil can splash out and unmetered air can upset engine running. Fit a correct replacement promptly to keep the Elysion happy and leak-free.

Popular questions about 2013 Honda Elysion oil caps

Where is the oil cap on a 2013 Honda Elysion?
On 2.4-litre K-series models it’s on top of the cam cover, easy to spot when the bonnet’s up. On V6 J-series variants it’s on the front bank’s rocker cover toward the radiator side. It’s a black cap marked for engine oil.

Can the Elysion be driven without the oil cap?
Best not. Without the cap, oil can splash out and contaminants can get in. It can also draw unmetered air, affecting idle and emissions. If the cap’s missing, switch off and fit a proper replacement before driving.

How tight should the oil cap be?
Hand-tight only. Seat it squarely and turn until it’s snug. No tools. If it won’t seat or keeps working loose, the cap or its seal likely needs replacing.
