Engine - Oil Leakage From Engine
TSB No. 210-2418 ed. 4Date April 2006
Distr. all
9-3 (9400)
OIL LEAKAGE FROM ENGINE
Car Affected
Saab 9-3 (9400) M99 - M03 with engine variants B205 and B235
Background
The flow through the crankcase ventilation may be inadequate in certain operating conditions, and oil leakage may then arise. Most common is leakage at the joint between the timing cover, the cylinder block and the cylinder head as well as leakage at the ventilation is also very important for avoiding increased oil consumption. Gasket replacement/resealing must only be carried out if the oil leakage does not cease after the following procedure.
In case of customer complaint, the following procedure must be carried out.
Symptom Description
Oil leakage from engine.
Parts Required
Procedure
1. Disconnect the battery's negative cable.
2. Remove the upper engine cover.
3. Install a new oil filter pipe.
4. Remove the hose from the pipe connection on the turbo's intake manifold.
5. Remove the hoses from the nipple in the camshaft cover. Check the condition of the hoses, replace if necessary.
6. Remove the old nipple and bushing from the camshaft cover and install the new nipple and bushing.
7. Raise the car.
8. Remove the oil trap's two upper hoses.
9. Remove the lower hose to the oil trap. Remove the stay to the intake manifold and the oil trap. If necessary, remove the generator positive cable.
10. Install the new oil trap, the lower hose to the oil trap (replace hose if necessary) and the stay for the intake manifold. If the positive cable was removed, connect it to the generator.
11. Lower the car.
12. Check the function of the check valve on the small circuit with 30 14 883 Pressure/Vacuum pump, replace if necessary. The arrow must point toward the throttle body.
NOTE
Arrow's direction on the check valve.
13. Man: Remove the vacuum pipe from the turbocharger delivery pipe.
14. Remove the upper turbocharger delivery pipe from the throttle body and cylinder head. Move the turbocharger delivery pipe aside.
15. Unplug the temperature sensor connector.
16. Detach and move aside the cable duct from the cylinder head.
17. Unplug the throttle body connector.
18. Connect the new hose kit (with T-connection) between the nipple on the oil filler pipe and the connection on the turbo's intake manifold.
19. Install the insulation under the throttle body coolant hose so that the insulation's short sides point upward.
20. Install the crankcase ventilation hose in so that the check valve is located above the coolant hoses. The crankcase ventilation hose must follow the route of the lower coolant hose through the intake manifold and then on to the oil trap.
21. Connect the oil trap's upper hoses. If the hose with part no. 55 560 463 is replaced then the nipple enclosed with the hose must not be used. Use the nipple enclosed with the spare parts kit.
22. Connect the new hose kit together at the T-connection.
23. Make sure that the check valve has good contact with both coolant hoses. Affix a cable tie around the insulation on each side of the check valve.
24. Plug the connector into the throttle body.
25. Fit the cable duct to the cylinder head.
26. Plug the connector into the temperature sensor.
27. Install the turbocharger delivery pipe. If necessary, replace the throttle body O-ring.
28. Man: Install the vacuum pipe.
29. Connect the hoses to the nipple on the camshaft cover.
30. Install the upper engine cover.
31. Connect the cable to the battery's negative terminal.
32. Set the correct time and date in SID.
