Don't know about links, but if you pull all the plugs and fill the holes with diesel, and refill 'em daily for a week, then you can try to turn the crank manually with a big wrench on the cranknut. If it won't turn, do it for another week, then another. If the engine won't turn after 3 weeks, it ain't likely to without a major. The main thing is to give it time, and don't try too hard or something (probably a ring) will break. The more easily it frees up, the better your chance is of having a tight, trouble-free engine which doesn't use oil. So don't pull too hard. And, like KB3 says, stand clear of the plug holes when you pull.
