Parts for your 2011 Toyota Camry-Sump plug washers

2011 Toyota Camry sump plug washer — what it does and how to look after it

Yes, a sump plug washer (also called an oil drain plug gasket) is used on the 2011 Toyota Camry. Technical documentation backs this: Toyota’s Repair Manual (TIS) for the applicable engines (2AZ‑FE 2.4L and, in some markets, 2AR‑FE 2.5L) instructs to “replace the gasket” whenever the drain plug is refitted and specifies tightening the plug to about 39 N·m (29 ft‑lb). Toyota’s genuine parts catalogue lists a dedicated gasket for the drain plug, commonly Gasket, Oil Drain Plug 90430‑12031 for these models. Aftermarket manuals (e.g., Haynes Toyota Camry 2007–2011) echo the same replace‑each‑service guidance.

On a 2011 Camry, the sump plug washer is a small, crush‑style gasket that sits between the drain plug head and the sump. When the plug is torqued, the soft aluminium (or copper) washer deforms slightly to create a reliable seal. That controlled “crush” prevents weeping and drips, even as the alloy sump and steel plug expand and contract with heat. It’s a tiny, low‑cost part that protects the engine from slow oil loss and the driveway from spots under the car.

For servicing, it pays to treat the washer as a single‑use item. Toyota’s procedure is to fit a new washer at every oil change, clean the mating surface on the sump, then tighten the plug to around 39 N·m. Over‑tightening to “make it stop leaking” is a trap, it can distort the washer, still leak, and risks damaging the sump threads. If a new washer isn’t on hand, reusing the old one in a pinch is possible, but it’s second‑best and should be checked soon after for any sign of seepage.

Correct sizing matters. The Camry’s drain plug uses a 12 mm gasket, genuine Toyota 90430‑12031 or a quality equivalent will do the job. Keeping a small pack of washers in the garage makes DIY services simple and helps avoid late‑night parts runs. During the oil change, always wipe away old oil from the area and inspect the plug for nicks or burrs—replace the plug if the flange is damaged, as even a new washer can’t seal against gouges.

• Tell‑tales of a tired or reused washer: dampness around the plug, a faint oil smell after a drive, or fresh drops under the engine.
• If any of these appear, fit a new washer and re‑torque the plug to spec.
• Stick to fresh engine oil and a new filter at each service—and a new washer every time.

What size sump plug washer does a 2011 Toyota Camry use?

It uses a 12 mm crush washer. The commonly specified genuine part is Toyota 90430‑12031. When refitting the drain plug, tighten to about 39 N·m (29 ft‑lb) on a clean, dry sealing surface to ensure a proper seal.

Should the sump plug washer be replaced at every oil change?

Yes. Toyota’s service procedure calls for a new washer each time the plug is removed. The washer is designed to deform once, reusing it can lead to weeps or drips. Given the low cost, it’s smart insurance at every service.

What are the symptoms of a bad or reused sump plug washer on a 2011 Camry?

Look for light oil dampness around the plug, the odd drop of oil on the driveway, or a faint hot‑oil smell after drives. If seen, swap in a new 12 mm washer and torque the plug correctly, if it still leaks, inspect the plug and sump sealing face for damage.
