Parts for your 2022 Toyota Land cruiser-Sump plug washers

2022 Toyota Land Cruiser sump plug washers — what they do and when to replace them

Short answer: yes, the 2022 Toyota Land Cruiser (J300 series) uses a sump plug washer on the engine oil drain plug. Toyota refers to it as a drain plug gasket and specifies replacement at each oil change in the Repair Manual and Owner’s Manual maintenance procedures. In the Toyota Electronic Parts Catalogue (EPC), common listings for the J300 include 90430-12031 (12 mm aluminium) and, on some variants/markets, 90430-14028 (14 mm aluminium). Typical drain plug torque is shown around 39–40 N·m in the repair procedures. Sources: Toyota Repair Manual for Land Cruiser 300 Series (Engine Oil — Replacement), Toyota Owner’s Manual (Maintenance), and Toyota EPC (Gasket, Drain Plug).

On the 2022 Land Cruiser, the sump plug washer is a soft, crush-type gasket that deforms slightly as the drain plug is torqued, creating a reliable seal between the plug and the alloy or steel sump. That little ring does the heavy lifting to stop weeps and drips after an oil change, and it helps distribute load so the sump threads don’t get flogged by over-tightening.

Toyota’s service information flags the washer as a single-use part. Once crushed, it won’t spring back the same way next time, reusing it risks seepage, which can make a mess, attract dust and mud off-road, and in the worst case lead to gradual oil loss. For the J300’s twin‑turbo V6 engines—petrol V35A‑FTS or diesel F33A‑FTV—keeping oil sealed and clean is vital, so fitting a fresh washer at each service is cheap insurance.

Best practice during a service looks like this:

• Confirm the correct washer size by VIN or measuring the drain plug thread (many J300 use 90430‑12031, M12, some markets/variants use 90430‑14028, M14).
• Clean the sump sealing face and the plug head.
• Fit a new crush washer and torque the plug to spec (around 39–40 N·m unless stated otherwise for your engine code).
• Warm the engine, check for any weeping, and recheck after the first drive.

Owners who tour on corrugations or hit the beach regularly should keep a couple of spare washers in the kit. If a washer must be reused in a pinch, inspect it closely and plan to replace it at the next opportunity. Over‑tightening to “stop a drip” is a trap—use a torque wrench, protect those sump threads, and the Land Cruiser will stay tidy underneath.

These details align with Toyota Repair Manual procedures (Land Cruiser 300, Engine Oil — Replacement), Owner’s Manual maintenance notes, and EPC part listings for “Gasket, Drain Plug”.

Popular questions

What size sump plug washer does a 2022 Land Cruiser use?

Most J300 models use Toyota 90430‑12031, a 12 mm aluminium crush washer with an M12 drain plug. Some variants/markets use 90430‑14028 (M14). The sure-fire way is to check by VIN in the Toyota EPC or measure the plug’s thread (M12 vs M14) before service.

Do you really need to replace the washer every oil change?

Yes—Toyota service literature treats the drain plug washer as single‑use. Reusing can lead to weeps, and over‑tightening to “make it seal” risks damaging the sump. A new washer each service is inexpensive and keeps the Cruiser leak‑free.

What’s the correct torque for the drain plug?

Repair Manual procedures for the J300 list the drain plug torque around 39–40 N·m. Use a torque wrench and avoid cranking it tighter, the crush washer does the sealing, not brute force. Always confirm the spec for your exact engine code.
