Have it towed home and fix it, you can't fix it in a parking lot. If it was my lot I'd have it towed if it was leaking oil all over the place, diesel oil makes a freaken mess!

Your going to need two cooler hoses, and a set of engine mounts. Might as well do the trans mount while your at it. Start spraying the oil cooler connections with PB blaster now so they come apart.
