This bulletin is reprint of administrative message 01-027 date 01/24/96, plus the claims matrix has been revised only for labor operation T2480. The
specific claims matrix changes are shown in bold type for your convenience.
General Motors has decided that certain S/T model vehicles built with 4.3L (VIN code "X" or VIN code "W") engines assembled by the Romulus engine
plant may exhibit higher than normal oil consumption and/or may experience spark knock on acceleration. These conditions may be due to improperly
installed valve stem seals.
To correct this condition, dealers are to replace the valve stem seals with a complete set of new intake and exhaust seals.
Vehicles Involved
Involved are certain S/T model vehicles built within the VIN breakpoints as shown in the accompanying image.
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle
Identification Number, owner name and address data, and are furnished to involved dealers with campaign bulletin. Owner name and address data
furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner name and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up
necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently
assigned.
