It's not worth paying a dealership to fix it. But if the rest of the car is in pretty good shape it may be worth putting some money into. There's tons of these cars in junkyards and you can get good motors and heads cheap, but they are all just as old. You cant see how many miles are on these things with the digital dash either. I did my heads with the motor in the car and it's a pretty tight space. With gaskets, machine work, timing set, water pump, and misc stuff you'll be out 4-500. That's with no labor. How much do you like the car and how much do you feel ok about putting in it? In the last 3 months I've got more in mine than it is worth, but it is worth it to me because I know I couldn't replace it with something I like as much. This may sound totally stupid, but I like the top of the door frame where my arm rests. It is nice and flat and just the right height. I had a 99 DeVille too and got rid of it because the arm out the window was uncomfortable. I just like these late 80-early 90 FWD sedans. Where do you live?
