My engine was recently replaced with one out of a 95 Cougar (insurance would not pay for any PI engine I found. They told the shop to find one closest to the year of my car). Anyway, this engine runs great, prob better than the one it replaced, but under the hood it is ugly as hell. Apparently the engine came from up north or was sitting for a while and it looks like it has a salt residue all over it. How should/can I clean it. I was thinking sanding it or using one of those brushes that go on the end of your drill (cannot think of the name of them). What do you guys think?
