Looking through your photos is like watching a horror show :vampire:.
A picture that struck me as significant in this sad slide show is this one

From an Australian engine rebuild perspective it looks to me like a hopeless case. The time and effort required to rebuild along with parts costs would make it more expensive than buying a used replacement engine though the cost and availability 
dynamics may be different in Haiti. 
No amount of honing is going to make these bores any good :no2:, so new liners would be required along with all the other bits needed to restore this engine to any semblance of good order. It may be a better solution to replace the engine with whatever diesel engine is available,  similar to the re powered American autos on Cuba.
Sorry to 'rain on your parade' and I hope others here can disagree with me and offer a better solution.
Deano :)
