I asked about a week ago and no one has answered. I was getting oil in the coolant along with loosing coolant. After doing some investigating and flushing it out ,adding some bars leak it appears to have helped. There is some black residue in the coolant tank now but not much. It still doesn't seem to be quite right. If this is a head gasket problem where would the oil be at the gasket. Just wondering. This thing runs good and it doesn't smoke. I was wondering if a cracked oil cooler may be the problem. One more thing-while idling air bubbles can be seen in the plastic overflow tank. it has a new cap even went to Ford and got it. thanks DAVID
