Parts for your 2012 Toyota Land cruiser-Sump plug washers

2012 Toyota Land Cruiser sump plug washers

Based on technical references, the 2012 Toyota Land Cruiser (200 Series) does use a sump plug washer (also called an oil drain plug gasket). Toyota’s 200 Series Repair Manual for both the 1VD‑FTV diesel and 3UR‑FE petrol engines specifies refitting the drain plug with a new gasket and tightening to the specified torque. The 2012 Owner’s Manual maintenance guidance echoes this “new gasket on installation” note, and Toyota’s Electronic Parts Catalogue lists a “Gasket, drain plug” for this model, commonly 90430‑12031 (12 mm) and, on some variants, 90430‑14008 (14 mm). So yes—this part is relevant and fitted on the 2012 Land Cruiser.

The sump plug washer on a 2012 Land Cruiser is a small aluminium crush ring that seals the drain plug to the alloy sump. When the plug is torqued down, the washer deforms slightly to fill microscopic gaps, stopping oil weeping out under heat and vibration. It’s cheap insurance against drips on the driveway and keeps the engine oiling system tidy and spot‑on.

Good practice is to replace the washer at every oil change. In Aussie and Kiwi conditions, that’s typically every 10,000 kilometres or 6 months, depending on usage. Reusing an old, flattened washer can lead to slow seepage, which tempts overtightening—never ideal on an alloy sump. Toyota’s spec calls for installing a new gasket and tightening the drain plug to around 39 N·m (check your exact engine variant). Stick to that with a torque wrench and you’re laughing.

There are a couple of sizes across the 200 Series range. Many petrol and some diesel models take a 12 mm gasket (Toyota P/N 90430‑12031), while other diesels use a 14 mm gasket (P/N 90430‑14008). The easiest way to be sure is to check by VIN with a parts counter or measure the plug’s shank/seat. Keep a few spares in the glovebox or with your filters—most reputable filter kits for the 200 include one.

Handy tips when servicing:

• Clean the sump face and plug head before refitting, grit can cause micro‑leaks.
• Never double‑stack washers, and don’t mix crush and bonded (Dowty) styles without confirming fit.
• If you’ve fitted an aftermarket magnetic plug, use the correct thickness washer so thread engagement remains proper.
• After refill, run the engine, shut it down, and check for any weep around the plug.

This tiny washer does a big job—fresh oil, fresh filter, fresh washer, and the Land Cruiser will keep touring without leaving little reminders on the garage floor.

What size sump plug washer does a 2012 Land Cruiser use?

Most use a 12 mm aluminium crush washer (Toyota 90430‑12031), though some diesel variants use a 14 mm washer (90430‑14008). Confirm by VIN or measuring the plug’s diameter at the sealing face to avoid guesswork.

How often should the sump plug washer be replaced?

Swap it at every oil change—about every 10,000 km or 6 months for typical AU/NZ service intervals. Replace sooner if there’s any sign of seepage after a service.

Can the washer be reused?

It’s a single‑use crush washer. Reusing increases the chance of weeping or overtightening the plug. If you must reuse once in a pinch, inspect for nicks and deformation, but plan to replace it at the next opportunity.
