Blown head gasket on 2006 Grand Prix. Car is in otherwise good shape. Worth fixing or replacing engine?
A head gasket is cheaper than engine replacement. Did the blown head gasket damage anything else? Hydro-lock the engine? Are you repairing it yourself? Paying someone?
You haven’t said how many miles on the engine - I wouldn’t do a head gasket if the engine had 300K but I might if it was 150K. You don’t describe the condition of the rest of the car other than “good shape.” That isn’t enough to make any real determination.
