Parts for your 2016 Toyota Camry-Sump plug washers

2016 Toyota Camry sump plug washers: what they do and when to replace them

According to Toyota’s 2015–2017 Camry Repair Manual (Engine/Hybrid System – Lubrication) and the Toyota Genuine Parts catalogue listing the oil drain plug gasket (commonly p/n 90430-12031) for this model, the 2016 Toyota Camry does use a sump plug washer. The manual explicitly instructs refitting the drain plug with a new gasket and torquing to spec, which confirms the washer’s relevance and use on 2.5L, 3.5L and Hybrid variants.

On the 2016 Camry, the sump plug washer is a small aluminium “crush” gasket that sits between the oil pan (sump) and the drain plug head. Its job is simple but critical: it deforms slightly when tightened to create a reliable seal, preventing those annoying weeps and driveway spots. Because it crushes to seal, it’s designed as a single‑use item.

For regular servicing, swapping the washer at each oil change is the tidy, trouble‑free approach. It costs little, saves mucking about with drips, and keeps the sump threads from being over‑tightened in a bid to stop a seep. If re‑used, the washer may not crush evenly a second time, and the Camry can develop a light oil mist or a slow weep around the plug after a few hundred kilometres.

Good practice on a 2016 Camry service looks like this:

• Remove the old washer from the plug and check it hasn’t stuck to the sump face.
• Wipe the mating surface clean, no sealants or thread tape should be used.
• Fit a new Toyota‑style 12 mm aluminium crush washer (e.g., 90430‑12031).
• Tighten the drain plug to about 39–40 N·m (around 29–30 ft·lbf) unless the vehicle‑specific spec says otherwise.

This applies across the Camry range for 2016, including the Hybrid: even though the Hybrid has additional seals on its filter housing, the sump still relies on a crush washer at the drain plug. If the plug’s been overtightened in the past, check the threads and the sealing land on the sump—any gouges can compromise sealing and may need attention before the next fill.

Signs the washer needs replacing outside of schedule include fresh oil around the plug, a damp sump face, or evidence of past over‑tightening (flattened, split, or heavily grooved washer). Keeping a handful of genuine or quality aftermarket 12 mm aluminium washers on hand makes each service quicker, cleaner, and drama‑free.

Popular questions about 2016 Toyota Camry sump plug washers

What size and part number washer does a 2016 Camry use?

The 2016 Camry typically uses a 12 mm aluminium crush washer for the engine oil drain plug, commonly referenced as Toyota p/n 90430‑12031. That’s a standard Toyota fitment across many models and suits the Camry’s M12 drain plug. Stick with quality aluminium crush types for a proper seal.

How often should the sump plug washer be replaced?

Replace it at every oil change. The washer is designed to crush once to form a seal, re‑using it can lead to weeps. Whether servicing at 10,000 or 15,000 kilometres, popping in a fresh washer each time is cheap insurance against leaks and over‑tightening.

What torque should be used on the 2016 Camry sump plug?

Toyota’s repair information specifies around 39–40 N·m for the engine oil drain plug on 2016 Camry engines. Always tighten to spec on a clean, dry surface with a new washer—no sealant or tape required. If unsure, check the exact spec for the specific engine variant.
