Parts for your 2016 Toyota Land cruiser-Sump plug washers

2016 Toyota LandCruiser sumpplugwashers: what they do and when to replace them

Yes, the 2016 Toyota LandCruiser uses a sump plug washer. Toyota’s 200 Series (J200) Repair Manual instructs replacing the oil drain plug gasket whenever the plug is removed, and the Toyota Electronic Parts Catalogue lists a separate drain-plug gasket for this model. For Australia and New Zealand variants, the common engines are the 1VD-FTV 4.5L V8 diesel and, in some markets, the 3UR-FE 5.7L petrol. Toyota parts data shows crush-washer gaskets are required: typically 14 mm aluminium for the 1VD-FTV (commonly referenced as 90430‑14008) and 12 mm aluminium for the 3UR-FE (commonly referenced as 90430‑12031). The workshop procedure also specifies correct torque and “replace gasket” at each service.

On the 2016 LandCruiser, the sumpplugwasher is a small, soft-metal gasket that sits between the sump (oil pan) and the drain plug. Its job is to provide a reliable, leak-free seal when the plug is torqued down. Because it’s a crush type, it deforms slightly to fill microscopic gaps, which is why Toyota advises replacing it every time the plug is removed. Reusing a crushed washer risks weeping leaks, drips on the driveway, and the temptation to overtighten the plug—which can strip threads in the sump. No one wants that headache under the bonnet.

As part of routine servicing, treat the sumpplugwasher as a consumable. A fresh washer costs next to nothing but protects an expensive engine. The LandCruiser’s service information typically calls for tightening the drain plug to around 39–43 N·m (varies by engine, always follow the spec in the exact manual for the VIN). With a new washer in place and correct torque, the seal is bang-on.

• Purpose: seals the drain plug to prevent oil leaks.
• Material: usually aluminium (soft enough to crush and seal).
• When to replace: every oil change or whenever the plug is removed.
• Tell-tales of trouble: oil mist around the plug, fresh drips, or needing extra torque to stop seepage.

For the 2016 Toyota LandCruiser, it pays to keep a couple of genuine-quality sumpplugwashers in the service kit. When dropping the oil, clean the sealing face on the sump, fit a new washer to the plug, install by hand to avoid cross-threading, then torque to spec. After the first drive, have a quick squiz for any signs of a weep—especially handy on models with bash plates where a tiny leak can pool before showing up on the ground. The right washer, fitted once, saves doing the job twice.

Note: some driveline plugs (transmission and diffs) also use crush gaskets, but sizes differ. This page focuses on the engine oil sumpplugwasher for the 2016 LandCruiser 200 Series.

What size sumpplugwasher does a 2016 Toyota LandCruiser use?

Most Australian and New Zealand 2016 LandCruiser 200 Series with the 1VD‑FTV V8 diesel use a 14 mm aluminium crush washer, while petrol 3UR‑FE variants commonly use a 12 mm aluminium washer. Because models and markets vary, it’s best to confirm by VIN in the Toyota EPC or match the old washer before fitting.

If in doubt, measure the plug’s shank diameter and the washer’s inner diameter, and use a genuine or OEM-quality part. A correct fit ensures the washer crushes properly and seals first go.

How often should the sumpplugwasher be replaced on a 2016 LandCruiser?

Replace the sumpplugwasher at every engine oil change. Toyota’s workshop procedure for the 200 Series specifies “replace gasket” whenever the drain plug is removed, because the washer is designed to crush once. Reusing it can cause seepage or lead to over-tightening.

If the plug has been out for inspection or any other reason between services, fit a fresh washer again. They’re inexpensive insurance for a leak-free seal.

Can the sumpplugwasher be reused if it looks fine?

Reusing a crush washer isn’t recommended. Even if it looks tidy, it’s already deformed and won’t crush uniformly a second time. That’s when weeps start, especially with hot, thin oil on long runs. A new washer lets the correct torque create the correct seal.

If a previous service reused the washer, keep an eye out for light oil mist around the plug and a faint drip on the bash plate. Swap in a new washer at the next chance.
