Parts for your 2013 Ford Falcon-Sump plug washers

2013 Ford Falcon sump plug washers

Yes, the 2013 Ford Falcon (FG MkII) uses a sump plug washer. Ford’s workshop literature for FG/FG MkII Falcons (Engine Lubrication section) and Motorcraft service information specify a threaded sump drain plug that seals via a replaceable washer. Local parts catalogues for BA–FG series Falcons from major suppliers also list compatible sump plug washers (typically copper crush or bonded rubber-on-steel), which confirms fitment and service intent.

On this Falcon, the sump plug washer’s whole job is to provide a reliable, leak-free seal between the drain plug and the alloy sump when the plug is tightened. As the washer compresses, it fills tiny imperfections in the mating surfaces so engine oil stays where it should. Most FG MkII six-cylinder variants commonly use a bonded seal (a steel ring with a rubber inner), though copper crush styles are also available and widely used.

As part of routine servicing, replacing the washer is cheap insurance. Once crushed, a washer doesn’t spring back perfectly. Reusing it can lead to weeping around the plug, oily undertrays, and a mess on the driveway. Best practice is to fit a new washer at every oil change, or at least inspect the old one carefully—if it’s flattened, nicked, or hardened, bin it and install a new one. When tightening the plug, avoid reefing on it, aim for the factory torque from the service manual and let the washer do the sealing. Over-tightening can distort the washer, damage threads, or even crack the sump.

Handy tips for Falcon owners and techs:

• Match the washer type to the plug and sump face—bonded seals are very forgiving on alloy pans, copper crush works well too if correctly sized.
• Clean the sump mating surface and plug head before refitting—grit can compromise the seal.
• If the plug’s flange is gouged or the rubber on a bonded washer has stuck to the pan, replace the plug as well.
• Dispose of used oil and washers responsibly—follow local regulations.

Done right, a fresh washer each service keeps the Barra-powered Falcon tidy, leak-free, and easy to live with—exactly how owners in Aus and NZ like it.

Popular questions

Does a 2013 Ford Falcon actually need a sump plug washer?
Yes. The FG MkII Falcon uses a drain plug that seals with a replaceable washer. Workshop and parts references for BA–FG models specify a sealing washer, and using a fresh one at service time helps prevent oil leaks.

How often should the washer be replaced?
Ideally at every oil change. Once crushed, the washer won’t seal as reliably if reused. If you’re stretching intervals, at least inspect it and replace if it’s flattened, marked, or hard. Washers are inexpensive and save headaches later.

Which washer type and size should be used?
Most 2013 Falcon sixes accept an M12 drain plug with either a bonded rubber-on-steel washer or a copper crush washer. Check the plug style on the car or a trusted parts listing by VIN to ensure the correct inner diameter and profile.
