"When things aren't going right – I mean, holy shit, you were dragging that whole motor halfway across the shop by an oil pan you had thought was unbolted - just step back and take a breather. It's easy to miss something – I do it, believe me. All those books you've been reading are in-service maintenance manuals – they aren't going to tell you what could happen, or things to look for if a part has been sitting for a while."
