Parts for your 2006 Honda Elysion-Sump plug washers

2006 Honda Elysion sump plug washers — what they do and when to replace

Technical sources confirm that the 2006 Honda Elysion uses a crush-type sump plug washer. Honda workshop literature for the Elysion (RR1–RR5) in the Engine Lubrication section specifies replacing the drain bolt washer at every oil change and tightening the drain bolt to approximately 39 N·m (about 29 lbf·ft). Honda genuine parts catalogues list an aluminium “Washer, Drain (14 mm)” commonly supplied as P/N 94109-14000 for these models and their K24A/J30A engine families. These sources collectively indicate the vehicle is designed to run a single-use aluminium crush washer on the sump plug.

The sump-plug-washers on a 2006 Honda Elysion do a deceptively important job. They’re soft aluminium crush washers that deform once to create a tight seal between the sump (oil pan) and the drain bolt. That controlled “crush” stops sneaky oil weeps and protects the sump face from scoring. On this Honda, the washer is a 14 mm aluminium type matched to the drain bolt and should be treated as a single-use service item.

As part of regular servicing, the advice is simple: replace the washer at every oil change or any time the drain bolt is removed. Reusing an old, flattened washer can lead to slow leaks, messy undertrays, and the risk of under-torquing or over-torquing the bolt to chase a seal. When fitting the new washer, clean the sump sealing face, thread the bolt by hand first, then tighten to about 39 N·m with a torque wrench. That’s plenty for an Elysion—no need to swing on a breaker bar.

There’s no fancy maintenance for sump-plug-washers, just sensible replacement. A genuine Honda washer (often noted as 94109-14000) or a quality equivalent is ideal. Avoid stacking washers, avoid sealants on the threads, and if the sump face is nicked from past overtightening, it’s worth lightly dressing it flat or replacing the bolt if its flange is damaged. For DIYers under the bonnet at home, keep a small stash of new washers with your oil and filter so one’s always on hand.

Signs it’s time to pay attention include a drip on the driveway, oil mist around the plug, or a washer that’s visibly deformed or grooved. Swapping the washer is cheap insurance, keeps the Elysion tidy, and helps ensure the correct torque is enough to seal without stressing the alloy sump. It’s a small part, but it makes servicing your 2006-honda-elysion sump-plug-washers straightforward and drama-free.

• Washer type: 14 mm aluminium crush washer

Popular questions about 2006 Honda Elysion sump plug washers

What size sump plug washer does a 2006 Honda Elysion use?
It uses a 14 mm aluminium crush washer that matches the drain bolt. This is the common Honda washer supplied across many models and is designed to be replaced each time the bolt is removed.

How tight should the sump plug be on an Elysion?
Torque the drain bolt to about 39 N·m (around 29 lbf·ft). Using a torque wrench helps avoid stripping threads in the alloy sump and ensures the new washer crushes correctly to seal.

Can the sump plug washer be reused?
Best practice is no—don’t reuse it. The aluminium washer deforms once to create a reliable seal. Reusing can cause weeping oil and encourages overtightening, which risks damage to the sump.
