Hello, I just purchased a 98 Deville. Was supposed to be a beater for two teenaged girls. However, I wound up falling in love with her and am thinking of keeping her for myself. The guy that I got her from told me that the engine overheats. He told me that it has been tested by "several mechanics" and that all that she needed was a new water pump. I took his word and gambled with the six hundred dollars he was asking. Long story short, I block tested it and it is almost certainly the head gasket. This car has 197k. The interior is surprisingly clean and the body is very straight. Almost everything on this car works perfectly. Do I have the head gasket replaced? Is it worth the time, money and effort? Or should I just replace the entire engine or just give up on her all together? I would love to hear from folks that might love this car as much as I do. Everyone else tells me to just dump her. Thanks in advance for your opinions.
