Hey guys and gals--I'm new to this forum and my baby is having a problem I need help with. I have a stock, 2000, v6, 3.8L mustang with oil in the water, but no water in the oil. I replaced the radiator as I was told that it was probably the oil cooler. It worked for about a week, but she's got oil in the water again. She runs great and stays cool. She doesnt have any major problems except that. I had the heads rebuilt about 12000 miles ago. Shes at 164000 miles. Any ideas would be helpful!!!
