Parts for your 2016 Subaru Exiga-Oil cap

2016 Subaru Exiga oil cap — what it does, where it is, and when to replace it

Technical sources confirm the 2016 Subaru Exiga is fitted with an engine oil filler cap. Subaru’s Crossover 7/Exiga Owner’s Manual (2015–2017, “Engine compartment” diagram) labels the engine oil filler cap clearly, and the Subaru FB25 engine service information and electronic parts catalogue list the cap and its seal as serviceable items. So yes — it’s absolutely relevant on this model.

On the 2016 Exiga (often badged Crossover 7), the oil cap lives up top under the bonnet on the right-hand cam cover, marked with the oil can symbol. Its job is simple but critical: seal the filler neck so dust and moisture stay out, keep oil from splashing out, and help the crankcase ventilation system maintain the right pressure. The cap uses a moulded seal/O-ring to do that sealing work.

As part of regular servicing in Australia or New Zealand, it’s smart to give the oil cap a quick once-over every 10,000–15,000 kilometres (or whenever the oil’s changed). Wipe it clean, check that the O-ring isn’t flattened, hard, cracked or swollen, and make sure the threads or bayonet tabs are tidy. A tired seal can lead to a light oil film around the filler neck, a warm oily odour after a drive, or in some cases a rough idle or warning light from a small air leak.

Replacement is straightforward: turn the cap anti-clockwise to remove, clean the neck, swap the seal if it’s perished, and refit by hand, turning clockwise until it’s snug. No tools or sealant required — just firm hand-tight. Overtightening can distort the seal or damage the cap. If the original’s gone missing or is cracked, a genuine cap that matches the FB-series engine is the safest bet for proper fit and crankcase sealing.

Why bother? Driving without a cap, or with a damaged one, can mist oil inside the engine bay, attract grime, and even affect how smoothly the engine runs. A good cap is cheap insurance — keep one in good nick and the Exiga will be happier for it.

• Inspect the cap and O-ring at every service.
• Replace if the seal is hard, cracked, or if the cap no longer tightens securely.
• Use a cap specified for the FB25 engine to ensure proper sealing.

FAQ

Where is the oil cap on a 2016 Subaru Exiga?
It’s on the top of the engine, typically on the right-hand rocker cover under the bonnet, marked with an oil can symbol. It’s easy to reach once any plastic engine cover is lifted off or moved.

What are signs the oil cap needs replacing?
Look for oil seepage or staining around the filler neck, a warm oily odour after driving, or a cap that feels loose or won’t seat properly. Any cracked or flattened O-ring is a cue to replace it.

Does the oil cap need a specific torque?
No. It’s designed to be hand-tight only. Turn it clockwise until it seats snugly, avoid tools or sealant. If it won’t tighten securely by hand, replace the cap or seal.
