Parts for your 2007 Holden Commodore-Oil seals

2007 Holden Commodore oil seals

Oil seals are definitely used on the 2007 Holden Commodore (VE). Technical sources including the Holden VE Commodore Service Manual (GM Global SI), the GM/ACDelco Genuine Parts catalogue, and popular workshop guides such as Gregory’s VE Commodore manual all list multiple engine, transmission and differential oil seals for this model. So yes—oil seals are relevant, fitted, and important on the VE.

On a 2007 Commodore, oil seals keep lubricants where they belong and grime out of critical components. They live at key rotating shafts and join points, like the front and rear of the crankshaft, the transmission input/output, and the differential pinion and axle stubs. When they harden or wear, oil escapes, leading to drips on the driveway, burning smells on the exhaust, or even low oil levels that can damage major assemblies.

Common spots owners or techs keep an eye on include:

• Front crank seal (behind the harmonic balancer)
• Rear main seal (between engine and gearbox)
• Transmission output shaft and selector/input seals (auto or manual)
• Differential pinion seal and side/axle seals

As part of routine servicing, it’s smart to inspect for fresh oil mist or wetness around the balancer area, the bellhousing, the tailshaft yoke, and diff flanges. A quick wipe-down and recheck after a drive helps confirm an active leak. There’s no fixed replacement interval—seals are generally done when they leak, or proactively during related work (for example, when the gearbox is out, that’s the time to consider a rear main).

Good practice when replacing seals includes using quality OE or reputable aftermarket parts, lightly lubricating lips with clean oil, checking the shaft surface for grooves, and installing square to the bore with the correct depth. If a seal sits over a worn groove, a sleeve repair kit may be needed. Always follow the workshop manual for torque specs and any sealant points.

If leaks keep returning, check crankcase ventilation
