Oil sludging in gasoline engines with ASSYST maintenance

system

Recently we have determined that time and time again oil

sludging occurs in gasoline engines with an ASSYST maintenance

system.

Oil sludging can lead to the following complaints:
D
engine oil consumption

D
engine smoke (white/blue)

D
influencing of oil level indicator

D
clogged oil filter, engine oil thickened like jelly

D
Check engine lamp illuminated

D
oil sludge visible during assembly job, e.g. in oil filter, in cylinder

head covers, condensation sludging
(engine 166) etc.

-----------------------------------------------------------------------------------------
The following list of causes may lead individually or as a combination
to engine oil sludging:

D
Crankcase ventilation inoperable, function orifices, bores,

passages in cylinder head cover, cylinder head, crankcase etc.

are mechanically sealed. A nonfunctioning crankcase

ventilation boosts loads on the engine oil through organic

nitrates. The risk of oil sludging increases.

The mechanical condition of the engine is always to be

checked, i.e. all engine oil drain orifices on the cylinder head

and crankcase and all crankcase ventilation ducts must be free

of obstacles. Crankcase breather lines may not be kinked.
Check the ventilation bores in the cylinder head covers.

-----------------------------------------------------------------------------------------

D
The engine oil used does not comply with the specifications in

Sheet 229.1 or 229.3 of the Specifications for Service Products.

The additive process, e.g. dirt-carrying capability, neutralization

capability and oxidation resistance as well as the quality of the

base stock influence sludging time.

Use of engine oils with best possible resistance to formation of

sludge, i.e. use only tested and approved engine oils (from

Sheet 229.1 or 229.3). The best protection is afforded by the

engine oils on Sheet 229.3, which fulfill more stringent

specifications with regard to preventing sludge and deposits
(see Sheet 221.0, page 11). These oils have a distinctly better

anti-sludge characteristic than other engine oils.

D
Sludging after adding a fuel or engine oil special additive.

Do not use fuel or engine oil special additives. More information

hereto is available on Sheet 219.0 of the Specifications for

Service products. Reference to customer not to use special

additives.

D
Engine oil change not performed according to ASSYST

specifications. At driven distances

exceeding > approx. 3000 km, engine oil sludging may occur.

-----------------------------------------------------------------------------------------
Comply with engine oil and filter change as under ASSYST

specifications. Observe remaining distance.

D
Fuel grade lies outside standard (regionally contingent). If

contaminated, deficient fuel is used, then engine oil sludging

may occur even where approved engine oil is used.

Operation with fuel, e.g. as under DIN EN 228. Clarify refueling

behavior of customer. If engine operation regional, is

temporarily possible with deficient oil only, then the startup

distance has to be individually reduced, i.e. the oil change

temporarily performed at an interval of, e.g. 10,000 km.

D
Radiator antifreeze penetration into engine oil, e.g. through an

internal engine leak (cylinder head gasket, casting porosity).

The engine oil sludges within a short period. The crankcase

ventilation clogs up and stops functioning. Condensation

sludging clogs up the oil separator cells

(engine 166).
Rectify coolant leakage. Clean all sludged engine parts, in

particular the crankcase ventilation parts. If the occurrence

repeats, and casting porosity is suspected, e.g. replace

crankcase.

GENERAL INFORMATION
GENERAL NOTES ON WORKING ON VEHICLES WITH LEVEL CONTROL/ADS - AH32.00-P-0002-01A
All models with code 216b, 216c, 217a, 480
Fig. 1: Identifying Box Wrench (116 589 00 17 00)

The following instructions should be followed when disconnecting and connecting pressure lines:
Clean contaminated line connections before disconnecting them. Seal disconnected lines and hoses and
connections to components immediately with blind plugs.
Only use open box wrench and special tool when loosening and tightening pressure lines to avoid damage to the
line connections.
Check the component concerned and line connections for leaks after assembly work on the suspension
system.
NOTES ON CHECKING OIL LEVEL ON VEHICLES WITH LEVEL CONTROL/ADS - AH32.00-P-0003-01A
All models with SA Code 217a/ 480
Observe the following prerequisites when checking the oil level in the oil reservoir:
1. The vehicle must be standing on its wheels.
2. Check the oil level when the vehicle is ready to drive:
Vehicle ready for use with oil and coolant reservoirs filled.
Full fuel tank - compensate for any missing fuel by placing additional weight in trunk.
Spare wheel and vehicle tool kit in vehicle.
Unladen vehicle. Remove any luggage, fuel canisters etc. from the vehicle.
On vehicles with level control /ADS, the oil level in the oil reservoir may fall below the "min." mark
on the oil dipstick when the vehicle is loaded.
