INTAKE MANIFOLD GASKET

CONDITION

General Motors has determined that certain 1993 Oldsmobile Cutlass Ciera model vehicles equipped with the 2.2L (RPO LN2, VIN 4) engine may have been assembled with an intake manifold gasket (between the intake manifold and the cylinder head) that can move out of position due to engine thermal cycling. This may result in rough idling, check engine lamp coming on, stalling and/or hesitation on acceleration.

To prevent this condition from occurring, retailers are to replace the intake manifold gasket on involved vehicles.

Any vehicles recently repaired using the correct Lower Intake Manifold Gasket (P/N 24574409), verified by a repair order, may be labeled and returned to the customer without further repair.

Should a question arise concerning the campaign involvement of a specific vehicle(s) within the breakpoints listed above, retailers should access the VISS (Vehicle Information Service System) for verification.
