Parts for your 2018 Volkswagen Amarok-Oil seals

2018 Volkswagen Amarok Oil Seals

Drawing on Volkswagen’s ElsaWin workshop manual for Amarok (Type 2H, MY2018), the ETKA parts catalogue, and ZF’s 8HP automatic transmission service literature, oil seals (radial shaft seals) are absolutely used on the 2018 Volkswagen Amarok. They’re fitted throughout the driveline: crankshaft front and rear, camshafts, gearbox and transfer case input/output shafts, axle flanges, and differential pinions and hubs.

These oil-seals do the unglamorous but vital job of keeping lubricants in and grit out. On the Amarok’s V6 TDI (and belt-driven 2.0 TDI where fitted), that means stable engine oil control at the crank and cams, on the ZF 8HP auto or manual boxes, it means transmission fluid stays put, and on the 4x4 system, diffs and transfer case seals keep gear oil where it belongs so bearings and gears last the distance.

There’s no fixed replacement interval—oil-seals are a “replace on condition” item—so smart servicing is about inspection and prevention. A good workshop will check for:

• Fresh oil mist or drips at the bellhousing, crank pulley, timing cover, and undertrays
• Gear oil weep at diff pinions, axle flanges, and transfer case outputs
• Oil on the sump guard or crossmembers after a decent run
• Burnt-oil smell near the exhaust from leaks blowing back

Helpful maintenance tips for an Amarok ute:

• Keep engine breathers/PCV and diff/transfer case breathers clear—pressure build-up is a seal killer.
• Use the correct spec oils and change on time, contaminated or overfilled oil can force past seals.
• Some VW crankshaft seals are PTFE style and must be installed dry with the correct guide—don’t pre-lube or they’ll fail early.
• If the crank rear main is leaking, expect gearbox removal. For diff pinion seals, correct pinion preload and new nut/crush sleeve may be required—this is precision work.
• If a shaft has a groove, a repair sleeve (speedi-sleeve) can restore the sealing surface.

For owners with the 2.0 TDI (timing belt), workshops often replace cam/crank seals when the belt is off if there’s any sign of sweating. For the V6 TDI (timing chains at the rear), seals are inspected routinely and replaced only if they leak. Either way, genuine or OEM-quality seals and proper install tools make all the difference for leak-free kilometres across Aussie and Kiwi conditions.

Popular questions

Where are the key oil-seals on a 2018 Amarok?
They’re at the crankshaft (front and rear), camshafts, gearbox and transfer case input/output shafts, and the front and rear diff pinions and axle flanges. The exact mix depends on engine and transmission variant, but every Amarok has multiple seals across the driveline.

Is it safe to keep driving with a small oil-seal leak?
A short trip might be okay, but it’s not ideal. Engine or gearbox oil on a hot exhaust can be a fire risk, and low fluid in a diff or transmission can quickly damage bearings and gears. Best to get it inspected and sorted promptly.

Should oil-seals be replaced preventively during servicing?
Generally, no—only when there’s evidence of leakage. An exception is the 2.0 TDI during a timing belt job, if a cam or crank seal shows any weep, it’s efficient to replace while access is open. On the V6 TDI (chain-driven), seals are usually replaced on condition only.
