Parts for your 2020 Honda Cr-v-Oil cap

2020 Honda CR‑V oil cap — what it does and how to look after it

Technical sources confirm the 2020 Honda CR‑V is fitted with an oil filler cap. The 2020 CR‑V Owner’s Manual shows the oil cap on the engine’s rocker cover in the Engine Oil section, the Honda Factory Service Manual instructs removing the oil filler cap during oil changes, and Honda’s genuine parts catalogue lists a specific “Cap, Oil Filler” for 2020 CR‑V engines. So the oil cap is absolutely relevant and used on this model.

On the 2020 CR‑V, the oil cap seals the top of the engine’s oil filler neck. It keeps dust and moisture out, prevents oil splashing out under the bonnet, and helps the crankcase ventilation system maintain proper pressure. That means fewer leaks, less oily vapour, tidier emissions, and a healthier engine over the long haul.

As part of regular servicing, the oil cap deserves a quick once‑over. A cap that’s cracked, warped, or missing its rubber seal can allow oil mist to escape and contaminants to sneak in. Owners might notice an oily film on the cam cover, a whiff of burnt oil after a drive, or even a rougher idle if the PCV system is upset by a poor seal. In some cases, a check engine light related to air leaks can pop up.

• At each service or oil change, remove the cap and wipe it clean. Check the rubber O‑ring/gasket for flattening, nicks, or hardening.
• Ensure the cap threads engage smoothly and that it seats fully. It should be snug by hand—no tools needed.
• If the cap is stubborn to turn, the threads may be contaminated, clean gently and avoid cross‑threading.
• Replace the O‑ring if it’s perished, it’s inexpensive and restores the seal.
• If the cap is cracked, warped, or won’t seal, replace it with a quality OEM‑spec cap.

Driving without an oil cap isn’t recommended. Oil can spray out, making a mess and potentially contacting hot components—messy at best, risky at worst. If the cap goes missing, it’s best to source a replacement before putting many kilometres on the vehicle.

For the 2020 CR‑V’s 1.5‑litre turbo engine common in Australia and New Zealand, the oil cap sits up top on the engine cover and typically notes the recommended oil grade. A quick visual check during routine servicing—every 10,000 km or 12 months, as per local schedules—keeps this simple but important part doing its job properly.

Where is the oil cap on a 2020 Honda CR‑V?

It’s located on top of the engine, towards the front, and marked for engine oil (often showing the recommended viscosity). Lift the bonnet, remove the decorative engine cover if fitted, and the cap is on the rocker cover/filler neck.

What are the signs the oil cap needs replacing?

Look for a cracked cap, a hardened or flattened rubber seal, oil mist around the filler area, or a cap that won’t seat or tighten by hand. A faint oil odour after a drive or light oil residue on nearby components can also point to a poor seal.

Is it safe to drive if the oil cap is missing?

Best avoided. Without the cap, oil can splash out and contaminants can enter the engine. If the cap’s lost, limit driving and replace it as soon as possible with an OEM‑spec unit to restore a proper seal and ventilation balance.
