Engine light came on, I had my mechanic do a 120,000 mile service and diagnose the dash engine light and the intake manifold was replaced. When I picked the car up I smelled diesel. I drove it 13 miles, when I got home I smelled diesel again. I opened the hood and there was diesel all over the left engine side. There was a wet, split fuel line, leaking fluid in the parking lot, a blue plastic set small rings (like the olympic symbol) sat near the split hose. It could have caused a fire, and other cars to be in danger from slick road, among other things.
