Parts for your 2006 Toyota Blade-Sump plug washers

2006 Toyota Blade sump plug washers

Yes — a sump plug washer is relevant and used on the 2006 Toyota Blade. Toyota’s E150-series service literature for the Auris/Blade platform specifies fitting a new crush-type gasket to the engine oil drain plug at refit, and the Toyota Electronic Parts Catalogue lists an “oil drain plug gasket” for both Blade engines released in 2006. Common Toyota part numbers seen for this model range are 90430-12031 (aluminium, M12) for the 2.4-litre 2AZ-FE and 90430-14022 (aluminium, M14) for the 3.5-litre 2GR-FE. Always confirm by VIN or measuring the drain plug thread before ordering.

The sump plug washer’s job is simple but crucial: it seals the drain plug to the alloy sump, so the engine oil stays where it should. It’s a soft, crushable ring (usually aluminium or copper) that deforms slightly when the plug is tightened, filling microscopic gaps and stopping weeps. Without it, even a correctly torqued plug can seep oil, leaving spots on the driveway and slowly dropping the oil level — not ideal for the Blade’s smooth four or grunty V6.

Because it’s designed to crush once, Toyota treats the washer as a consumable. If the plug comes out, fit a new washer. It’s a low-cost part that helps protect an expensive engine.

• When to replace: every oil change, or any time the drain plug is removed.
• What to use: a quality aluminium or copper crush washer that matches the plug size (M12 or M14 depending on engine).
• Fitting tips: clean the mating face on the sump, place the new washer against the sump (not stacked on old ones), then torque the plug to the spec in the Toyota repair manual for your engine. Don’t over-tighten — let the washer do the sealing.
• What to watch for: dampness around the plug, oil mist on the undertray, or fresh spots under the car after a service. If seen, replace the washer and re-torque.

Owners who service their 2006 Toyota Blade at home often keep a small pack of the correct washers in the toolbox. Genuine items are inexpensive, and quality aftermarket equivalents are fine as long as the size and material match. Reusing an old, flattened washer might seem harmless, but it’s a common cause of slow leaks that only show up after a few hundred kilometres.

Does the 2006 Toyota Blade need a new sump plug washer at every oil change?

Yes. Toyota’s service guidance calls for a new crush washer whenever the drain plug is refitted. It’s cheap insurance against leaks and helps ensure the plug reaches the correct clamp load without over-tightening.

Which washer size fits my 2006 Toyota Blade?

It depends on the engine. The 2.4-litre 2AZ-FE commonly uses an M12 aluminium washer (e.g., Toyota 90430-12031), while the 3.5-litre 2GR-FE typically uses an M14 aluminium washer (e.g., Toyota 90430-14022). Confirm by VIN, checking the EPC, or measuring the plug thread.

Can the old washer be reused if it’s not leaking?

It’ll sometimes “get by,” but it’s not recommended. A crush washer deforms once, reusing it increases the chance of a slow weep later. If you must reuse in a pinch, monitor for drips and replace with the correct new washer as soon as practical.
