CAMPAIGN:EGR VALVE INOPERATIVE EGR VALVE MAY PLUG
ALL 1980 OLDSMOBILES EQUIPPED WITH MODELS/YEARS FEDERAL 3.8L-2 BBL. ENGINES W/O COMPUTER CONTROLLED EMISSION SYSTEM
THIS CAMPAIGN BULLETIN SUPERSEDES CAMPAIGN 80-E-2 DATED MAY 30, 1984. BECAUSE OF A RECENT COURT RULING, THE PREVIOUS AGE/MILEAGE LIMITATION HAS BEEN DELETED. ALL 1980 MODEL YEAR VEHICLES WITH 3.8L FEDERAL ENGINES ARE TO BE INCLUDED IN THIS CAMPAIGN REGARDLESS OF AGE OR MILEAGE.
CONDITION
General Motors has determined that some 1980 Oldsmobiles equipped with 3.8L 2 bbl. engines may be emitting pollutants in excess of Federal Emission Standards.
The EGR valve may have a plugged passage causing the EGR valve not to operate, resulting in an increase of exhaust emissions.
VEHICLES INVOLVED
All 1980 Starfire, Cutlass and Delta 88 models equipped with Federal 3.8L - 2bbl. (VIN Code A) engines without computer controlled emission systems.
DEALER ACTION
As a result of a recent court decision clarifying the Federal Emission Recall Program, the previous 5 year/50,000 mile limitation has been deleted from Campaign 80-E-2. All vehicles affected by this campaign should be subjected to the service procedure of this bulletin at no charge to the owner regardless of vehicle age or mileage. If, during this initial inspection, the EGR valve is found to be inoperative, the valve should be replaced, also at no charge to the owner.
If the valve is functioning satisfactorily, the owner has been requested to have the EGR valve function checked at 30,000 mile intervals. These 30,000 mile inspections should also be performed at no charge to the owner. However, should any subsequent 30,000 mile inspection indicate EGR valve replacement is necessary, it should be accomplished at no charge to the owner only if the vehicle has less than 50,000 miles.
If there is evidence of intentional disablement of the EGR system, the dealer is to notify the vehicle owner of this condition and ask the owner if he/she wants the system restored. The cost of restoration will be the responsibility of the vehicle owner.
Vehicles in dealer used car inventory are to be campaigned in accordance with the guidelines prescribed in this bulletin, prior to resale of the vehicles.
SERVICE PROCEDURE
A. Inspection of EGR Valve-
1. Raise vehicle hood and cover fenders.
2. With engine at operating temperature, running at idle and with transmission in "Park," place fingers beneath the EGR valve in order to contact the diaphragm.
CAUTION:
EGR VALVE MAY BE HOT. WEARING GLOVES IS RECOMMENDED TO AVOID BURNING FINGERS.
3. Rapidly increase engine speed to approximately 2,000 rpm and return to idle. Repeat 4 or 5 times with a pause each time. The diaphragm should have moved up and down during this procedure if system is functioning correctly.
4. If no up or down motion was felt when performing the engine rpm increase sequence, as outlined in step 3, check for vacuum at the EGR valve hose at higher engine speeds. If vacuum is present, replace EGR valve, step B.
5. If EGR valve functions properly, do not replace valve. Install campaign identification label, step C.
B. EGR Valve Replacement-
1. Remove air cleaner assembly.
2. Remove EGR valve attaching bolts and remove valve.
3. Remove all traces of gasket material from EGR valve mounting surface. Do not allow any gasket material to fall into EGR passages.
4. Obtain correct Service EGR valve (refer to Parts Information) and install new valve with new gasket. Tighten bolts to 27 N.m (20 lbs. ft.).
5. Check for proper EGR valve operation, step A.
6. Install air cleaner and install campaign identification label, step C.
C. Campaign Identification Label Installation Procedure -
Each vehicle inspected or modified in accordance with the instructions outlined in this procedure will require a campaign identification label. Each label provides a space to include the campaign number, the five (5) digit dealer code of the dealer performing the campaign service, and the date vehicle was campaigned. This information may be inserted with a typewriter or ballpoint pen. When installing label, clean the surface of the radiator upper mounting panel in the area of Emission Label and apply the campaign label.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
