2022 Toyota Land Cruiser (LC300) Oil Filler Cap

Technical sources confirm the 2022 Toyota Land Cruiser uses an oil filler cap. The Toyota Land Cruiser 300 Series Owner’s Manual (2022) shows the “ENGINE OIL” filler cap in the engine compartment overview and the do‑it‑yourself maintenance section. Toyota’s Repair Manual (LC300) and the Electronic Parts Catalogue list a “Cap Sub‑Assembly, Oil Filler” for both the 3.5L twin‑turbo petrol V6 (V35A‑FTS) and the 3.3L twin‑turbo diesel V6 (F33A‑FTV). So yes, an oil cap is fitted and it’s absolutely relevant.

On the 2022 Land Cruiser, the oil cap does more than just plug a hole. It seals the top of the engine’s oil fill neck, keeping dust, water and grit out—vital when the vehicle spends time off‑road—and helping maintain correct crankcase conditions. A good cap prevents oil mist from escaping and stops a messy film building up over the engine bay. It’s a simple part, but if it’s loose, missing or its seal is perished, expect leaks, odours, and potential contamination that can accelerate wear.

As part of regular servicing (typically every 10,000 km or 6 months in AU/NZ, depending on use), the oil cap deserves a quick once‑over. After topping up oil to the grade specified in the owner’s manual, fit the cap squarely and do it up hand‑tight—just a firm nip, don’t over‑tighten. Wipe away any residue so you can spot fresh leaks easily.

• Inspect the cap’s rubber seal/O‑ring for flattening, hardening or cracks, replace if it’s not supple.
• Check the threads on the cap and filler neck for cross‑threading or debris, clean with a lint‑free rag.
• Make sure the “ENGINE OIL” marking is upright and the cap seats evenly—no wobble.
• If the cap was lost or ran without one, change the oil and filter, contaminants may have entered.
• Use a genuine or high‑quality equivalent cap matched to the LC300 engine, poor fits can weep or back off.
• After deep‑water crossings or dusty tracks, re‑inspect the cap and seal at the next stop.

Replacement is straightforward: if the seal’s tired, the cap’s cracked, or it won’t hold snugly, swap it. It’s inexpensive insurance for the Land Cruiser’s high‑output V6s. Keep a clean spare in the kit if touring remote—small part, big peace of mind.

Popular questions about the 2022 Toyota Land Cruiser oil cap

Where is the oil filler cap on a 2022 Land Cruiser?
It’s under the bonnet on top of the engine, clearly marked “ENGINE OIL”. On most LC300s it sits on the cam cover, easily reachable without removing engine covers. If unsure, the engine bay overview in the owner’s manual points directly to it.

What are the signs the oil cap or seal needs replacing?
Look for fresh oil mist around the filler neck, a burnt‑oil smell after driving, or a cap that doesn’t tighten smoothly. A hardened or cracked O‑ring is another giveaway. Any of these are reasons to replace the cap or seal.

Can driving without an oil cap damage the engine?
Yes. Unsealed, the engine can fling oil out and suck dust or water in, especially off‑road. If the cap has been missing, avoid driving, refit a correct cap, and consider an immediate oil and filter change to protect the engine.
