What started out as a ticking, progressed to a knocking, and metal shavings in the oil shows that the engine is terminal. It's a 2001 Ford F250 Diesel with 155K, so it's less than halfway through its life span and I've only owned it for 3 months.
I've been trying to work out what the best thing to do is here and I've been getting great advice, and sympathy.
I’m leaning toward getting a donor vehicle and pulling the complete engine and doing a full transplant, I think it will be simpler than doing a long block, and if I can get a good engine I think it will be a good move.
There are a few limiting factors in this plan:
My personal finances are low right now.
It’s mid winter here in the Sierras and the truck doesn’t fit into my garage so I either need to have some good weather for the transplant or I need to find a place indoors to do the work.
I haven’t done an engine transplant before, but I do have the Chilton manual

Is this job too big for me? Or do I just need the right tools and help from some friends?.
Have I overlooked something, is this engine still serviceable?
Given the situation I’m in what would you guys do? I could really do with some insight from those of you who know much more about this than I do.
