Parts for your 2007 Honda Elysion-Sump plug washers

2007 Honda Elysion sump plug washers — small part, big job

Yes, the 2007 Honda Elysion does use a sump plug washer. Technical references to the Honda Electronic Parts Catalog for the RR1/RR2 Elysion and the Honda Workshop Manual for the K24A and J30A engines specify an aluminium crush washer on the engine oil drain plug. The listed part is the 14 mm drain plug washer (Honda p/n 94109-14000), and the service instructions call for replacing the washer at each oil change and tightening the plug to the specified torque (typically around 39 N·m). That combination stops seepage and protects the alloy sump threads.

On this Elysion, the sump plug washer is a soft, single‑use seal that deforms slightly when the drain plug is tightened. That tiny crush is what creates a reliable, leak‑free seal between the plug and the sump. Without it, the plug can bottom out on metal, weep oil, or tempt heavier hand‑tightening that risks stripping threads. Honda’s service documentation is pretty clear: fit a new washer whenever the oil is changed.

For owners and workshops across Australia and New Zealand, it’s a simple and inexpensive bit of maintenance that pays off. A fresh 14 mm Honda‑spec washer helps keep the Elysion’s K24A 2.4 or J30A 3.0 V6 tidy underneath, makes correct torque achievable, and prevents those annoying spots on the driveway. If a washer gets reused too many times, it can harden or dish, leading to slow weeps that only show up days later.

Good practice when servicing a 2007 Honda Elysion:

• Use a new 14 mm aluminium crush washer (Honda 94109-14000 or quality equivalent) at every oil change.
• Clean the sump plug and seating face on the pan, remove old washer remnants.
• Tighten the plug to the factory torque spec (around 39 N·m for most Honda petrol engines) — avoid over‑tightening.
• After first heat cycle, have a quick look for any sign of weep and nip to spec only if needed.

These points line up with Honda’s workshop guidance and parts listings for the Elysion platform. Keep a handful of genuine or equivalent 14 mm washers on the shelf and the job stays quick, clean and by‑the‑book.

Popular questions

Does the 2007 Honda Elysion always need a new sump plug washer at oil changes?
Honda’s service information recommends replacing the crush washer at every oil change. It’s designed to deform once to seal properly. Reusing can lead to seepage or require extra torque, which isn’t great for the sump threads.

What size and type of washer suits the Elysion’s sump plug?
The Elysion uses a 14 mm aluminium crush washer commonly listed by Honda as p/n 94109-14000. Aluminium is preferred for consistent crush and compatibility with the alloy sump, copper equivalents can work if they match dimensions and quality.

What torque should the sump plug be tightened to?
Honda petrol engines of this era typically specify about 39 N·m for the drain plug. Always confirm for your exact engine (K24A or J30A) in trusted service data. Correct torque with a fresh washer gives the best seal without stressing threads.
