Okay, what's cheap? I see you are in the Tacoma area, so I searched the local CL.
Hey, the American spirit is built on making something you need with what is at hand, but if you can get something even better cheap, well that's true too.
Here are 4 diesel engines complete and running, each for 500 bucks. I doubt you can find anyone to build diesel pistons for the /6 for that, plus compression, fuel system, pump, etc.

Please note that each of these (except the Ford) come with fuel tank, lines, engine cradle, exhaust system, cooling system, electrics, and other support systems that are designed and built to support the engine on diesel. This is already included in the price. In fact, each of these include additional parts that can be sold off to recoup some or all of the purchase price, or be saved for future projects.


diesel with generator $300
