Parts for your 2016 Holden Commodore-Oil seals

2016 Holden Commodore oil seals

Oil seals are absolutely used on the 2016 Holden Commodore (VF Series II). This is confirmed by Holden/GM technical literature, including the VF Series II Service Manual procedures for “Crankshaft Front Oil Seal Replacement” and “Rear Main Oil Seal Replacement” for the V6 and V8 engines, plus sections for “Automatic Transmission Output Shaft Seal Replacement” (6L50/6L80) and “Rear Drive Axle Pinion Oil Seal Replacement”. The GM Electronic Parts Catalogue (EPC) and ACDelco service parts listings also catalogue these seals for VF models. So yes—oil seals are relevant and fitted to this vehicle.

On a 2016 Commodore, oil seals do a simple but vital job: they keep engine, transmission and differential oil where it should be, and stop dust, water and road grime getting in. Common seals on this model include the front crankshaft seal (behind the harmonic balancer), the rear main seal (between engine and gearbox), the automatic or manual transmission output shaft seal (around the tailshaft yoke), and the rear differential pinion and axle seals. When they’re healthy, the Commodore stays tidy under the bonnet and under the car, and fluids last as they should.

There’s no fixed replacement interval for oil seals on the VF, they’re replaced on condition. As part of normal servicing (typically every 15,000 km or 12 months), a technician should check for fresh oil weeping, damp dust build-up around seal lips, a burnt-oil smell after a drive, spots on the driveway, or oil tracking from the crank pulley, bellhousing, tailshaft or diff nose. Catching a small weep early can save a bigger repair later.

When it’s time to replace a seal, proper tools and OEM-spec parts matter. The lip must face the fluid, the bore and shaft surfaces need to be clean and burr-free, and the seal should be driven square to the specified depth. Lightly lubricating the lip on install helps. On LS V8 rear main seals, careful handling of the one-piece carrier, correct sealant use and torque pattern are important. For 6L80 autos, it’s smart to check the output shaft bushing and tailshaft yoke for wear so a new seal doesn’t start weeping again. Engine crankcase ventilation (PCV) and diff breathers should be clear—excess pressure will push oil past even a brand-new seal.

• Inspect at each service, replace only if leaking or damaged.
• Use quality seals and the right drivers, avoid hammering them in.
• Verify breathers and related bushes/yokes so the repair lasts.

Popular questions about 2016 Holden Commodore oil seals

Do 2016 Commodores actually have oil seals, and where are the main ones?
Yes. The key seals are the front crankshaft seal, rear main seal, transmission output shaft seal (auto or manual), and rear differential pinion and axle seals. These are documented in Holden’s VF Series II service procedures and parts catalogues.

How often should oil seals be replaced on a VF Commodore?
There’s no time or kilometre schedule—replace on condition. Have them checked each service for weeping or dampness. Many seals last well past 150,000 km, but hard use, heat, aged rubber or blocked breathers can bring replacement forward.

What are the signs of a failing oil seal on a 2016 Commodore?
Look for oil mist or drips at the crank pulley, bellhousing, around the tailshaft on autos/manuals, or at the diff nose and axle ends. You might notice oil spots on the driveway or a hot-oil whiff after parking. If spotted, get it inspected promptly to avoid fluid loss or contamination.
