Parts for your 2006 Toyota Blade-Sump plug washers

2006 Toyota Blade sump plug washers: are they used, and what should owners know?

Yes, the 2006 Toyota Blade uses a sump plug washer (also called a drain plug gasket). Toyota’s engine repair manuals for the 2AZ-FE four-cylinder and 2GR-FE V6 specify refitting the engine oil drain plug with a new gasket at each oil change and torquing the plug correctly. Toyota parts catalogues for Blade models (AZE154H, GRE156H) list a crush-type drain plug gasket, commonly Toyota p/n 90430-12031 for the 12 mm plug used on many Toyota engines. These directions appear consistently in Toyota service documentation and EPC listings, which call the part a “gasket, drain plug” and note replacement on reassembly.

On the 2006 Toyota Blade, the sump plug washer is there to seal the drain plug to the alloy sump without needing excessive torque. It’s a small, soft aluminium crush washer that deforms slightly as the plug is tightened, creating a reliable oil-tight seal. Without it, the plug can seep, the sump threads can cop a hard time if over-tightened, and owners may end up chasing annoying drips on the driveway.

For routine servicing, Toyota workshop procedures advise replacing the washer every time the oil is changed. It’s cheap insurance: a fresh washer helps the plug reach the correct clamp load at the specified torque (typically around 40 N·m / 30 ft·lb for many Toyota petrol engines—always check the exact spec for the engine variant). Most 2006 Blades with the 2AZ-FE use the aluminium crush washer 90430-12031, many 2GR-FE applications use the same spec in various markets, though the catalogues should be checked by VIN to be sure.

Good workshop practice for Blade owners and techs looks like this:

• Have a new genuine-equivalent crush washer ready for each oil change.
• Clean the sump mating face and the plug head, don’t reuse damaged or hard washers.
• Install the plug with the new washer and torque it to spec—no need to “gorilla” it.
• After the first heat cycle, have a quick look underneath for any weeping.

Signs a washer’s due or wasn’t replaced include a light oil halo around the plug, drips after parking, or needing to overtighten the plug to stop a leak. If the plug’s been reused many times, consider a new plug as well. Keeping on top of this tiny part keeps the Blade’s engine tidy, avoids contamination on undertrays, and saves owners from oil-loss dramas between services.

Popular questions

What size sump plug washer does a 2006 Toyota Blade use?

Most 2006 Toyota Blade models use an aluminium crush washer to suit a 12 mm drain plug, commonly Toyota part number 90430-12031. Because the Blade was sold with different engines, it’s smart to confirm by VIN against the Toyota parts catalogue, especially for the V6.

How often should the sump plug washer be replaced?

Replace it at every oil change. Toyota’s service literature for the 2AZ-FE and 2GR-FE specifies installing the drain plug with a new gasket each time. It’s a low-cost part that prevents leaks and protects the sump threads by avoiding over-tightening.

What torque should be used on the drain plug?

Many Toyota petrol engines of this era specify about 40 N·m (30 ft·lb) on the drain plug when used with a new crush washer. Always follow the torque value for the specific engine code in the Blade to avoid damaging the sump or under-tightening the plug.
