I have a friend who is getting 2 cars for free one is a 1980 264 Volvo Diesel and the other is a 1979 300D! The story is that they drove just fie to their destination, owner bought 2 new cars and these have sat! I was told they have been there for 5 years. So thursday we are going out to retrieve them. The tanks were drained saturday and we were gonna do a quick oil change on them, fill the tanks prime the injector pump and see what happens.

Is there anything I should/shouldn't do? Any tips would be great!
