* M112/M113 oil capacity is 8 liters.
* Oil should be 140°F-160° F [60°-71°C].
* If using the suction method, cut the end of the tube at a 45 degree angle.
* Warm the engine slightly so the oil flows easily and then it usually won't suck the tube closed.
* Run the engine for 5 to 10 minutes to heat up and thin the oil.
* Turn off engine prior to removing oil.
* Make sure the car is level. If not, you won't be getting all of the oil out of the pan, no matter which method you use.
* Forget about refilling the new oil via the Oil Filler Cap.  While you have the [[oil filter]] assembly out, pour the fresh oil down that huge hole. Less chance to spill, no funnel needed and no funnel to clean up afterwards.

Replacing heat exchanger and oil filter housing seals

Heat exchanger and oil filter

A common source of engine oil leaks are faulty seals at heat exchanger (17 and 23) and oil filter housing (35). They can be easily replaced during regular oil flush, but require a 46mm socket.

Parts:

  • Sealing ring: heat exchanger on oil filter hoising: A1121840261 (Elring 130240 / Febi bilstein 49403 / Swag 10949403)
  • Sealing ring: heat exchanger on oil filter hoising: A1121840361 (Elring 130250 / Febi bilstein 49402)
  • Sealing ring: oil filter housing on timing case: A1121840061 (Elring 137100 / Febi bilstein 173982)

If an oil leak occurs a year after replacing these seals, you need to check the crankcase ventilation system - there may be overpressure in the crankcase.

  • Pressure port cover A1120150630 8 EUR
  • Pressure port seal A1121840280 6 EUR / Elring 131050 2 EUR

Pressure port gasket A1121840280

Check oil pressure

Shown on engine 112:
  • 1 - Oil pressure gauge
  • 2 - Connection fitting
  • 3 - Sealing ring
  • 4 - Screw plug
  • 5 - Sealing ring
  • 6 - Remote thermometer
  • 7 - Dipstick
  • 9 - Fan shroud
  1. Wait until engine is stone cold
  2. Unscrew oil pressure screw using 6mm hex
  3. Screw in fuel pressure gauge with 12mm x 1.5 adapter
  4. Start the engine
  5. Bring engine up to operating temperature (approx. 80 °C).
  6. Note down the pressure readings
    1. When the throttle is opened, the oil pressure must rise without any delay.
    2. At idle ~700 RPM oil pressure should read >=0.7bar, at 3000 RPM oil pressure should read >=3.0bar.
  7. Wait until engine cools down
  8. Screw back the plug
  9. Run engine and check for leaks

Torque specification:

  • Screw plug to crankcase: 20 Nm
