Found this in my oil pan

If it turns out that was just some excess RTV sealant that came off, well so be it. Many a unknown problem was found looking for a non-problem. Good luck, and keep us posted.

Thanks. Since it's not rubbery and feels/bends like copper, and all sources of copper-like metal that might make it to the oil pan seem to be bearings (I have a cast iron distributor gear and it's in good condition), it's the only thing I feel comfortable doing.

I was pretty bummed, but I've made peace with it.
