Sorry, this is lengthy. I bought a Ford 5000 for $800.00 with a select-o-speed to rob the front-end bolster off of to put on my 5600. After robbing the front-end bolster, I found another one and put the tractor's front end back together. It had a turbo that I could not get parts for, and the seals leaked oil back into the exhaust valves. I removed the turbo, changed the head, intake, and exhaust gasket, and put brand-new fuel injectors on it. I also adjusted the valves and noticed while checking the timing that someone had a yellow mark on the 30-degree mark, not zero. My question in all of this is if the timing is off, will it cause it not to run correctly? It did run before I took the turbo off, but it ran a little rough sometimes, which I thought was the oil leaking back into the head. It still ran and drove pretty well. When I took the turbo off, it did not run at all. It puffs white smoke when I try to start it, but it will not run; it only puffs white smoke. Did someone adjust something or set the timing differently because it had a turbo? It also continues to emit white smoke after I stop trying to start it. I can shoot a bit of either in it, and it fires for a second. Thoughts or suggestions? I want to sell this when I am done because I think it would make someone a great restoration project.
