It was there originally as a safety backup, incase the tensioner went out. It has become a problem, though, as it tends to crack and completely snap off of it's mounts. The danger of it snapping and damaging the valves seems to preclude it's use as a failsafe, so it is deleted. OUT WITH IT!

Lauren: very odd indeed. My upper guide (and lower upper guide, damn this is getting confusing) are both metal. Mayhaps they had been replaced when the car had it's 100k timing belt job before I bought it. . . Anyhow, out with them too!

I think I've got the timing issue taken care of. According to my FSM, sparks at tdc, thus I set the #1 piston at TDC by the crank pulley, and find the rotor spot for spark at #1 cylinder at that point, then adjust with the timing light. Excellent.
