Changine Rocker-Arm O-Rings...
I am heavily considering replacing the lower spark plug tube O-rings. I've been researching heavily. There is a part, however, that I am a little uneasy about... marking and then pulling the timing belt off to release the tension for when I remove the rocker arm assembly.
Before removing the rocker arm assembly, I suggest removing the timing belt off the camshaft gear. This will help relieve the force pulling down on the camshaft gear end. Paint a line from the cam gear to the timing belt so you know how to realign the two parts later so your cam timing is not out synchronization. To remove the timing belt, on the cam gear end you will find an adjustment nut (14mm), which you want to loosen 1 full turn, push the timing belt on intake side inward, then retighten the adjustment nut snug again. This will loosen the timing belt enough for you to slip it off the cam gear (after your mark the belt to the gear for later reference). It may still take some force to remove the belt.
After the timing belt is marked and take off, I can proceed with removing the rocker arm assembly and replacing the 0-rings. Then I'll replace the rocker arm and then slide the belt back on making sure to align the marks on the crank...do a valve adjustment and replace valve cover...
Questions are ...
1) I've never messed with the timing belt and am a little worried about getting it back on and set with the correct tension. Is there a special tool for this.

is this all there really is to getting it back on and tensioned...
Reinstall the timing belt and set the belt tension. The timing belt should already be in it's loose state if you have followed the directions. Slip the belt back on, lining up the marks you made previously to keep the cam timing the same. After the belt is on the cam gear, put a mark on one of the cam gear teeth. Now go to the adjustment nut for the timing belt tension (14mm) and loosen it one full turn, then turn the crank counter-clockwise (wratchet, 19mm socket and 6" 1/2 inch extension) until that cam gear tooth mark you made moves the distance of 3 cam gear teeth. Finally, go back to that adjustment nut and snug it down good. This sets the tension on the timing belt.

nm...
further research and reveals that the tension from the timing belt will not pop the cam shaft up while the rocker arm is off (so long as you don't accidentally turn the engine over while the rocker arm is off).
