Hello all, I bought a 1980 International scout diesel with a sd33 engine, that was sitting outside for about 7 years, neglected. I towed it home, changed oil, sprayed oil in the injector holes for start up, poured diesel in it, and it started right up, but stalled shortly after. The problem that i am having is the engine will not stay running. I use the hand pump to prime fuel pressure and it will run for about 5 mins. When running it blows large amounts of smoke out the blow by tube. I am not familiar with this engine, hoping someone here as been there done that with these engines. Im ready to rip my hair out. Any info will be helpful, and appreciated. This vehicle is bone stock and has 42k original miles on it. Was used as a security vehicle, so it idled most of its lifetime.
