I just got back from a 400 mile trip with my car (what I thought) running great the whole time. Perfect temps and oil pressure the whole way. Got back home, unloaded the car, and went to my shop. Still nothing seemed wrong. About an hour or so, noticed a big pool of oil under the car. Looked around, oil all over the front of the motor, belts, pulleys everything. checked the oil, added some, and fired it up. Oil flying everywhere. Tried cleaning it as best as I could at the moment, and couldn't find any broken lines or obvious leaks, just oil everywhere. Maybe the front main seal? Sound familiar to anyone? Not really looking forward to tearing the whole thing down right now. It's an 84 300sd. If it is toast (for me at least), at least it gave me one last worry free trip....
