Parts for your 2007 Ford Falcon-Sump plug washers

2007 Ford Falcon sump plug washers — what they do and when to replace

Based on technical references, the 2007 Ford Falcon (BF series) does use a sump plug sealing washer. The Ford BF Falcon Workshop Manual (engine lubrication, Section 303-00) specifies fitting a new drain plug gasket/washer during oil change procedures, and major Australian parts catalogues for BA/BF list replacement sump plug washers for the inline-six and V8 variants. That makes the sump plug washer a relevant, serviceable item on this model.

The humble sump plug washer is a small hero on a 2007 Falcon. Its whole job is to seal the drain plug to the sump so the engine oil stays put, even as the alloy pan and steel plug expand and contract with heat. On the BF’s Barra inline-six, XR6 Turbo and Boss V8 engines alike, the washer crushes or compresses to take up tiny imperfections on the mating faces. That stops annoying drips on the driveway and guards the sump threads from over-tightening abuse.

Depending on what’s been fitted before, owners may see either a soft-metal crush washer (usually copper or aluminium) or a plug with a bonded sealing ring. Both styles are common in local parts listings for BA/BF, and both are treated as consumables. Best practice is to replace the washer at every oil change. It’s inexpensive insurance compared with chasing leaks later.

Service tips for the Falcon are straightforward. Clean the sump face and plug head, pop on a fresh washer, thread the plug in by hand first, then tighten to the workshop manual’s torque spec for the specific engine and plug type. Avoid swinging on the ratchet — over-tightening can distort the washer and damage the sump. After the refill and a quick run, check underneath for any weeps and nip back the plug only if needed. If it still weeps with a new washer, inspect the sump’s sealing face for nicks.

Signs a new washer is due:

• Oil mist or a slow drip at the drain plug after a service
• Washer looks gouged, flattened or work-hardened
• Previous plug used a bonded seal that’s perished or split

Handy hint for Aussie and Kiwi Falcon owners: keep a couple of spare washers with your oil filter. Whether it’s petrol or LPG E-Gas, a fresh washer every service keeps the Barra or Boss tidy and happy.

Popular questions

What size washer does a 2007 Ford Falcon use?
The BF Falcon commonly uses an M14 drain plug, so a washer with around a 14 mm inner diameter is typical. Variations exist between engines and replacement plugs, and some plugs use a bonded/captive seal. It’s smart to match the new washer to the plug removed, or check a reputable AU/NZ parts catalogue for the exact engine code.

How often should the sump plug washer be replaced on a BF Falcon?
Every oil change. The washer is designed to crush or compress once for a reliable seal. Reusing it risks weeping, especially on alloy sumps. Given the low cost, replacing it each service is the tidy, no-fuss approach.

Can the old washer be reused in a pinch?
If there’s no new washer handy, a single reuse may get by, but it’s not ideal. A previously crushed washer can’t conform properly a second time, and bonded seals harden with age. Replace at the next opportunity to avoid drips and potential sump thread damage from over-tightening.
