Hello, I'm new here and of course I am looking for help. I do have some knowledge of the IDI 7.3 Turbo but, I had a big oil leak develop at idle today. My truck is a 1994 F350 crew cab Dually 7.3L IDI Factory Turbo. What I have is a pretty big leak that is on the rt. side of engine above that runs onto the starter. The leak starts high on the engine and I am unable to locate where it starts? I believe it is from the turbo oil line that is on top of the turbocharger. The line that connects to the turbo on top then bends around and drops down going towards the right side of the motor and that is where I lose sight of it. From the amount of oil leaking from the RT side I suspect this might be the one?
Anyway, I haven't been able to locate a diagram of the turbo oil lines. Does anybody know were the turbo oil lines start and end ? I hope I have a good enough discription ? Thank you
