| Complaint: | See above. |
|---|---|
| Cause: | Oil return orifice between main bearing and seal ring to crank case not properly machined, causing overpressure in this area, resulting in an oil leakage. |
| Production: | Production process changed as of engine No: 11 041 547 |
Remedy:
In case of a customer complaint disassemble rear crankshaft seal ring and check oil return orifice (i.e. a wire). Orifice must be completely machined (Diameter 5 mm).If OK, assemble with new rear crankshaft seal ring. If NOK, replace short block.
Please note: If a whistling noise occurs, especially at idle speed in the area of the radial shaft seal (transmission side) it might be that the orifice (connection crank case ventilation) in the elbow hose (air cleaner to throttle valve body) has not properly drilled. Due to pressure differences the mentioned whistling noise can occur. The noise disappears when the oil dip stick is pulled out, because of crank case ventilation.
Remedy: Replace part.
