I do agree that a D1 is a better starting point. When I got stuck in CO with my '95 a few months ago a local mechanic and I completely rearranged the engine bay in two days. Youre not going to do that with a D2 4.6. ..
Lets keep that in perspective; you had to rearrange your engine bay because you had converted your truck to diesel with a non LR diesel engine. If you had had the same failure with the LR, you would have just replaced the necessary parts without modification.
I lost my power steering pump in Artesia, NM (about a "million miles" from nowhere). I ordered another from British Pacific, had it overnighted and the local chevy dealer installed it. It took an extra day because they had to order the proper serpentine belt. So, even with a Rover engine you can get parts with overnight service.
My point to this young man is, these trucks are more expensive to maintain than wrenching on Jeeps. FOr the items he cant fix he'll have to go to a mechanic with the proper computer tools. Bottom line is these cars are more expensive to fix, and unless the OP has parents helping him, or he's has a significantly above average income, he's going to find it much more expensive which could be problematic for him. Personally, I think he is getting bad advice on this thread.
