Remove

  1. 1. Remove sheathed glow plugs
  2. 2. Raise vehicle all the way
  3. 3. Remove engine compartment cover or right engine splash guard
  4. 4. Set crankshaft to "1st cylinder TDC" following direction of engine rotation • The markings (1) must align

Note. The cams of cylinder no.1 must face upward - cam position can be checked through the oil filler port. If cylinder no.1 cams are not facing upward, turn the crankshaft one revolution to "Cylinder no.1 TDC".

  1. 5. Affix guide marking to torsional vibration damper • Guide marking must be exactly 180° across from TDC marking
  2. 6. Lower vehicle all the way
  3. 7. Unscrew oil filling nozzle cover

Important. Carefully and slowly open coolant compensation tank cover. Risk of burning!

  1. 8. Unscrew coolant compensation tank cover
  2. 9. Withdraw oil dipstick

Measure

  1. 10. Calibrate pressure loss measuring device

Note. Follow manufacturer's instructions

  1. 11. Attach pressure loss tester to no.1 cylinder • Use KM-6367
  1. 12. Engage 4th gear; apply handbrake
  2. 13. Check 1st cylinder pressure loss • Max. pressure difference between individual cylinders - approx. 10 % • Pressure loss per cylinder should not exceed 25 % • Check the following for air discharge to locate any damage: – Intake ports – Exhaust system – Coolant compensation tank, dipstick guide tube – Oil filler port – Glow plug thread bores
  3. 14. Switch adapter and pressure loss tester to no. 3 cylinder
  4. 15. Repeat pressure loss test for 3rd, 4th and 2nd cylinder

Note. Continue rotating crankshaft by 180° to positioning mark or TDC mark
