MERCEDES-BENZ OIL LEAK REPAIR
Melbourne Euro specialises in Mercedes-Benz oil leak diagnosis and repair in Melbourne.
If your Mercedes is leaking oil, leaving oil underneath the vehicle, producing a burning-oil smell or requiring frequent oil top-ups, we can locate the source and repair the leak correctly.
We repair oil leaks across Mercedes-Benz petrol, diesel and Mercedes-AMG engines at our specialist workshop in Campbellfield.

COMMON MERCEDES-BENZ OIL LEAKS
Mercedes-Benz engines contain numerous gaskets, seals and oil-system components that can develop leaks with age, kilometres and repeated heat cycles.
Common oil leak areas include:
- Rocker / valve cover gaskets
- Oil filter housing
- Oil cooler and seals
- Timing cover
- Camshaft seals
- Front crankshaft seal
- Rear main seal
- Engine sump / oil pan
- Turbocharger oil lines
- Vacuum pump
- Oil pressure sensors and switches
- PCV / crankcase ventilation system
Oil can travel across engine components and undertrays before reaching the ground, so the location of the oil underneath the vehicle may not be the actual source of the leak.
This is why Melbourne Euro generally suggests performing an engine wash if needed to determine the exact cause and location of the oil leak.
MERCEDES ROCKER / VALVE COVER OIL LEAK
A leaking Mercedes valve cover or rocker cover gasket can allow engine oil to run down the side of the engine or onto hot components.
Common symptoms include:
- Burning-oil smell
- Smoke from the engine bay
- Oil around the top of the engine
- Oil running down the engine
- Oil underneath the vehicle
Depending on the engine, the leak may involve the gasket, cover itself or crankcase ventilation components.
MERCEDES OIL FILTER HOUSING & OIL COOLER LEAK
The oil filter housing, oil cooler and associated seals are another potential source of Mercedes-Benz engine oil leaks.
Symptoms can include:
- Oil around the filter housing
- Oil collecting around the engine
- Oil running down the engine block
- Burning-oil smell
- Oil underneath the vehicle
We inspect the area to identify exactly which seal or component is leaking before replacing parts.
MERCEDES TIMING COVER OIL LEAK
Oil leaks can also develop around the front timing cover and associated seals.
Because these areas can be difficult to access, correct diagnosis is important before dismantling the engine.
Melbourne Euro can identify the source and determine the appropriate repair for the particular Mercedes engine.
MERCEDES REAR MAIN SEAL OIL LEAK
The rear main crankshaft seal is located between the engine and transmission.
A leaking rear main seal can cause oil to appear around the engine-to-transmission area or underneath the vehicle.
Because replacement can involve significant labour, the leak should be properly confirmed before the transmission is removed.
MERCEDES TURBO OIL LEAKS
Turbocharged Mercedes-Benz engines can develop oil leaks around:
- Turbocharger oil supply lines
- Oil return lines
- Seals and connections
- Related engine oil fittings
Oil around the turbocharger does not automatically mean the turbo itself needs replacing.
We diagnose the source before recommending repairs.
SIGNS YOUR MERCEDES HAS AN OIL LEAK
Common symptoms include:
✓ Oil underneath the vehicle
✓ Burning-oil smell
✓ Smoke from the engine bay
✓ Oil around the engine
✓ Low engine oil warning
✓ Frequent oil top-ups
✓ Oil level dropping between services
If your Mercedes is losing oil but there is no visible leak, the engine may also be consuming oil internally and further diagnosis may be required.
MERCEDES OIL LEAK DIAGNOSIS
Some Mercedes oil leaks are obvious. Others require cleaning and inspection before the actual source can be identified.
Diagnosis can include:
- Engine inspection
- Oil leak tracing
- Cleaning contaminated areas where required
- Inspection of gaskets and seals
- Crankcase ventilation assessment
- Oil level and condition check
- Electronic diagnosis where relevant
Our objective is to repair the source of the leak rather than simply replace the nearest oily component.
MERCEDES OIL LEAK FAULT CODES
Most external engine oil leaks do not generate a specific fault code.
However, related oil-pressure, oil-level or crankcase ventilation problems can sometimes produce diagnostic faults such as the following:
P0520 • P0521 • P0522 • P0523 • P0524
These relate to engine oil pressure sensor/circuit or oil-pressure conditions, depending on the vehicle and fault.
A fault code does not confirm the location of an oil leak. Physical inspection and diagnosis are still required.
MERCEDES-AMG OIL LEAK REPAIR
Melbourne Euro also repairs oil leaks across supported Mercedes-AMG engines.
AMG engines can have complex lubrication, turbocharging and crankcase ventilation systems, making correct identification of the leak particularly important before major components are removed.
We can diagnose and repair Mercedes-AMG engine oil leaks, turbo oil leaks, gasket leaks and seal leaks.
