A limited number of the above 1984 models may experience sticking of 2.6L engine oil pump relief valves due to mis-machined valve bores. This can
lead to excessive oil pressure, rupturing of oil filters and loss of engine oil on affected vehicles..
To prevent such failures, vehicles known by engine build code to have the incorrect bores must be repaired by installing new relief valve plungers of
slightly modified end dimensions.
The vehicle population is defined in the following section. Information to assist in completion of repairs is included in the Service Procedure section of
this letter (A. Domestic Vehicles; B. Imported Vehicles).
