Good morning, i have a very poorly 1958 diesel L/R on my farm in Spain. Apparently it was running but was left parked with veg oil in it. Now completely gundged up. I am stripping out the whole fuel system to hopefully clean it out. The injectors were very grim and i assume the injector pump is too. It now seems the engine is seized aswell after standing for 5 or 6 years. Once i get the head off what would be the best next step, drip diesel into the cylinders, tap it with wood etc ? I've never had to deal with a seized engine before. Thanks for any ideas.
