Yikes. I hope so, too, having just done a short block for other reasons. The oil light is for pressure, right? So once it warms back up outside you could do the post-new-engine method of building pressure back. As in, pull the fuel pump fuse, crank a bit, rest, crank a bit, rest... a few times to see it the light goes off. No ignition = less damage risk. Have no idea if that's the best way, but it seems it couldn't hurt. Too bad the damn oil pump is buried in there. How often do those go bad?
Can you throw a heat lamp or something under it to warm the oil pan?
