This is where I currently am.  I'm starting to get all of the accessories installed on the OM617 Mercedes Turbo-Diesel.  Aside from the power steering pump, every single accessory is brand new.  The alternator is a John Deere 150amp upgrade from the stock 75amp alternator.
Every seal in the motor has been replaced, as well as timing chain.  I rebuilt the turbo and replaced the intake/exhaust gasket.  I deleted the EGR and cleaned in the inside of the intake as well.
I've got fuel lines on order, as well as a bracket to work with the stock Jeep throttle cable.  Cooling hoses have come in, and I'm waiting on a custom oil filter housing that converts the internal paper filter to a canister spin-on style.  I've got a brand new upgraded oil cooler as well.  Power steering lines are one of the things I'm working on now.
I expect she'll be running in a matter of weeks.
