My engine's got some orange stuff inside the block from the previous owner I noticed once I got it. I cant get it treated at a machine shop because I need it up and running soon. I'm wondering the best way/product to flush it out.
I kept it running for about 10 mins with a hose in the radiator and the drain plug out about 2 times but no luck.

Here's what she looks like right at this moment:
