Service Recommendations - For Severe Conditions
87peugeot03BULLETIN NO. 232
DATE: April, 1987
SUBJECT: SERVICE RECOMMENDATIONS FOR XN6 VEHICLES OPERATING UNDER SEVERE CONDITIONS
INFORMATION
On XN6 engines, complaints of oil leak between the timing cover and crankshaft pulley on high mileage vehicles can in some cases be attributed to partial blockage of the positive crank-case ventilation system. (Build-up of condensation moisture)
This problem may occur on vehicles which are operated under severe climatic and driving conditions (i.e. high humidity, extreme cold weather and repeated short distance driving).
SERVICE PRECAUTIONS
Extensive short distance stop-and-go driving:
- Change oil and filter at half the recommended intervals
- Periodically inspect and if necessary clean:
^ the oil trap (1) in P.C.V. recirculation tube (left side of engine block)
^ the 1.2 mm diameter calibrated orifice (4) (fitting in intake manifold)
^ check condition and routing on P.C.V. hoses
