When getting a used, bare aluminum engine for possible rebuild/build-up, is there a reliable way to check the block for cracks at home? I know that a seemingly good looking block doesn't mean it has no unseen cracks. I know there is Magniflux, but wasn't sure that worked with aluminum blocks. Can if be sprayed with a product to reveal cracks after a thorough cleaning? Thanks!
