My stepson has a slight cooling leak near the rear head by the timing chain cover on a '02 Taurus 3.0 Vulcan. He said about 8 oz a month he has to add to recovery tank. The car only sees city driving with very rare country driving with 68,000 miles on it. It looks to be a fairly involved task of getting to it since many parts have to be removed. He has started buying some parts and tools to fix it, but I advised him to add some bars stop leak or just keep adding coolant as needed because he would like to sell it soon and buy a used truck. If he starts tearing it apart and needs help, I might be loading up my truck with tools and going to my MIL's house where he is staying while in college and doing it in her driveway. Has anyone done this before and what was the most PIA trouble you dealt with. I put a lot of work into some vehicles of mine because I still own them and plan to for quite some time. I drive Chevys but Ford has their own way of doing things too. Thanks for any tips.
