I was putting the generator back on my coupe when I found this laying on the edge of the engine block. I was scraping off the edge of the block and it was stuck in the goop. It is the size of a penny but it looks like it has been hammered to make it thinner. I checked it with a magnet and it is copper. Any ideas what it could have been used for?
Freeze plug replacement?
Make sure all three freeze plugs are in place. The floor would be rather wet if you add water with it missing.
It "COULD" have been a penny during the depression that was hammered to make a bushing to tighten up the steering. The repairman realized it needed the full thickness penny and, while laying under the car, he handed the hammered penny to his son, who laid it on the generator. After completing the job, he crawled out and went for a test drive. The hammered penny fell down between the generator and engine block, where it remained until you found it. OR NOT!
Wow Mike - I have finally found someone with an imagination as active as mine!
IT would have been cupped shaped. But I like the story!
It could have been the mark of an engine rebuilder including the oversizes of the bore and crank. Rebuilders often use a round metal tag.
