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.
