How can I stop the spring from turning with the nut without getting a special tool? I tried wedging a flathead in the spring but it didn't work. Could I used a pair of needle-nose vice-grips to attach the plate at the top of the spring to the spring? Would that be enough to stop the spring from rotating with the nut?
Also, is there a way to turn the crankshaft from above?
Diesel giant suggests turning the engine by turning the power steering pump bolt. I tried this and the cyl camshaft lobes didn't move at all. I've been turning the engine over with the ignition, and it's hit or miss and really time consuming. How many rotations of the power steering pump bolt should I make before expecting the lobes to move?
Feeling a bit vulnerable with my baby's valve cover off, but excited about the prospect of hearing her purr like a kitten...
Thanks in advance for any suggestions.

Here are my remembrances of my first 617 valve adjustment:
1) I used the power steering nut with additional pressure on the belt to achieve rotation. Putting a gigantic 27mm socket on the crank nut seems impossible because of the closeness of the radiator. I bought a long handle box wrench at Harbor Freight for this job. It was far from a perfect solution.
2) I hope I am in time to help. The spinning nut is easily rectified by getting the largest screwdriver in your toolbox. Place it vertically next to the cam bearing tower and let the shank of the screwdriver impede the CW turning of the hex nut. This is a clean solution and does no harm to the mechanisms. I am not going to discourage you from buying a third wrench from other enthusiasts. I assume they will work also. I am meticulous and the interposition of the screwdriver shank worked for me.
Good Luck,
