Hello guys. I started to work on my 62 econobox this summer. I pulled the 200ci out of it to clean and paint it. I was really happy to see a reconditioned tag on the block and clean top under the valve cover. I pulled the oil pan off today but before prying it off with a screwdriver, I hit the sides with a rubber mallet. The engine was almost upside-down. ,when I pulled the pan,there was some big grit on the bottom but im afraid that some fell inside the bottom end.. I can't see anything tho. The grit was not magnetic,almost like carbon build up and a tiny sliver of glass. Should I be worried? Is there a way to flush everything down? I will have more questions as I put this beast together. Thanks hamb.
