I want to thank everyone for the help given and the patience shown. After having the valve cover gaskets replaced, new radiator and coolant, the car drives almost like a new one. no more smell from the engine after driving for a while, with the new fuel filter the car gets pretty good gas milage. The noise from under the front left fender has been delt with and much quiter, that runs the cruise control which work perfect. I have the cadillac chrome wire wheels that really shine in the sunlight. I drove on I-4 here in Florida over the week end to a car show in Daytona Beach and she really got the looks and kept up with newer cars. I love a CADILLAC and this one is so special. Thanks again for helping some one that reallys knows nothing much about a car's running.
