Can anyone tell me how to go about replacing a destroyed oilpan. My daughter ran over a mailbox and the surrounding large rocks and then stopped at a tree! I'm trying to determine if the car is worth fixing, but I've been told that it will take $500 just to replace the pan so that I can fill the engine with oil and see if the thing is destroyed or not. That info and the estimates for body and frame repair will tell me if I need to part it out or I can keep my little baby for another 10 years. So I'm trying to determine if I can possibly replace the pan myself. What will I need to do? Do I need any special tools? I do not have an air wrench, will one be needed?
