I don't know if this is the place to post but I was wondering if there is anyone out there that is experienced when it comes to aluminum corrosion. I am about to take an Auto Repair shop to court because I gave them an engine with 5,000 miles on it to swap in to my car and when I received my car back there was an engine in it that had nasty, thick orange corrosion all over and it wasn't corroded equally either. It looks like it was piced together. They only had it for 2 months but they said this is how quickly engines corrode. The pic on the far left and far right are the before pics with the nice clean head circled and the one in the center is after I got it back. Thanks for any help in advance.
