Yesterday, I bought the engine and dropped off the van with the mechanic.
The engine sat for a year under a tent outside, so I hope it is still good. Tony, the guy who sold me the engine, was a cooking oil pro, who had his own setup (i hope to buy it off him), and fueled his two trucks with it. The engine came out of a truck which was totaled by a tree falling on it.
Regarding putting the engine on, he told me it needed a fuel return line, and a wire harness for the glow plugs, and another battery.
He sold it to me for 750$ including the torque converter.
