Hello. I'm in the process of rebuilding my EJ257 out of my '04 Sti. I performed a dye penetrant inspection of the block, and the test revealed a precisely shaped crack on both sides of journal number 5. This crack is also on both block halves. Maybe this is a casting feature, but it seems more like a separate part that has been installed in some manner during the block manufacturing process. Attached are pictures from each side of the journal.
I'm wondering if this is normal, or if the block is damaged?
Thank you for taking the time to view my post.
