2020 Toyota LandCruiser Oil Cap — What It Does and How to Look After It

Technical sources confirm the 2020 Toyota LandCruiser is fitted with an engine oil filler cap. The 2020 LandCruiser Owner’s Manual identifies the oil cap under the bonnet as part of the engine compartment layout. Toyota Repair Manual illustrations for both the petrol V8 and the 4.5‑litre diesel show the cap mounted on the rocker/valve cover. Toyota’s Electronic Parts Catalogue also lists the oil filler cap and its seal for 200 Series LandCruiser models current in 2020. So yes, an oil cap is present and relevant on this vehicle.

On the 2020 LandCruiser, the oil cap does much more than just give a place to pour oil. It seals the filler neck so the crankcase stays closed, helping the PCV system manage blow‑by gases, keeping oil where it belongs, and stopping dust and moisture from getting in. The cap usually carries the recommended oil viscosity as a handy reminder, and a healthy rubber seal on the underside keeps things airtight.

As part of routine servicing, this is a simple item worth a look. With the engine off, spin the cap off, check the O‑ring or gasket for hardening, cracks, or flattening, and make sure the mating surface on the cover is clean. A quick wipe of the threads and a tiny smear of fresh engine oil on the seal helps it seat smoothly. Refit hand‑tight only, no tools needed. If the cap won’t click or snug down properly, replace it.

Driving without the cap is a bad idea. Oil can mist out, dust can get in, the engine may idle poorly from unmetered air, and you could end up with warning lights and a big mess under the bonnet. If the cap is lost or damaged, park up and fit a correct replacement before heading off again.

• Replace the oil cap if there’s visible cracking, a missing or brittle seal, persistent oil weeping around the filler, a fuel/oil smell after driving, or if it no longer tightens positively.
• Always match the oil grade shown on the cap and in the Owner’s Manual for your exact engine and climate in Australia or New Zealand.
• At every service interval, include the oil cap inspection alongside your oil and filter change.

FAQs

Where is the oil cap on a 2020 Toyota LandCruiser?

It sits on top of the engine’s rocker/valve cover under the bonnet and is labelled “Engine Oil”. Location varies slightly by engine, on V8 models it’s easy to spot near the front of the cover. The Owner’s Manual diagram points right to it.

What oil grade should be on the cap, and does it have to be followed?

The cap shows the viscosity Toyota specifies for that engine and market. Stick with the grade and specification in the manual and on the cap to protect the engine in Aussie and Kiwi conditions. If in doubt, a dealer can confirm by VIN.

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

No. Without a proper seal, oil can spray out, contaminants can get in, and the engine may run rough. Stop, switch off, and fit a correct replacement cap before driving any further.
