I have a 2001 Cadillac Deville with a 4. 6(y) motor while I love the car the motor is the pits it is very costly using over 1qt between oil changes and now I have a misfire and lost of coolant and was told that my head gasket had blown and my crankcase halfs are leaking and I was told to fix it it would be a new engine at the cost of $8k so I guess I will have to deal with the random misfire because I cant afford to fix it you would think since Cadillac is gm's luxury brand they wouldn't have the customers deal with this sloppy engine also I have had the oil drip on the exhaust and start a small fire so now I will have to try and baby this thing.
: the contact stated the engine light illuminated and the vehicle was difficult to start. An independent mechanic put the vehicle on a diagnostic testing machine and determined the vehicle needed crank shaft position sensors. The Cadillac dealer agreed there was a problem with the sensors and informed the contact the sensors were being replaced with upgraded sensors.
