I am looking to purchase this old moth balled project. Its powered by a Buick 215 V8. This motor has been sitting outside exposed to the California elements for around 15 years, it is close to the coast and has had some salt fog hanging around causing surface rust. It was parked full of anti freeze years ago. The dipstick shows no water in the pan. Being an aluminum motor are there other types of issues different then a iron block I should be concerned about and looking for? Can I treat this like a typical "long time sitter" and fill it with diesel for a few days to loosen everything up? Thanks for your reply, appreciate it.
