Whatever you do, don't turn the crankshaft nut CCW if you go a little bit too far. Go all the way around CW again. I did this and broke the crankshaft nut loose...this snowballed into even more problems. May not be as easy to do with plugs pulled. (Yeah I know it's supposed to take 6 foot breaker bars etc. to loosen that nut, but the last person to tighten it was at a dealership!)
