A Test of my Patience

I have stated before that patience is not one of my better virtues.
One of my favorite sayings is "Just keep swinging and walking forward and something is bound to fall down eventually".
This does not work well with cars.
In my battle with the Z, It has taken another round on points.
I put the new head gasket on and torqued it down.
When you take off the head you need to make a piece of wood 1 1/2 inches wide by 9 1/2 long to jam in between the two halves of the timing chain to ensure that the chain tensioner remains in place. Otherwise the tensioner drops out and you have to tear the front of the engine apart to get the timing chain back on.
I dutifully made the block of wood, and jammed in between the two chain halves. It remained in place while I worked on the head.
I put the timing gear on the chain and was maneuvering it in place. It was within 1/16" of being in place. The damn stick kept interfering with the bolt that attached the gear to the cam, So I took the bolt and got it started by hand. Then I removed the stick, since there was tension on the timing chain.
You can probably guess what happened next.
The bolt popped loose before I could tighten it, and the gear dropped down, releasing the tension on the chain, thereby allowing the chain to relax and the tensioner popped out.
Now I get to tear the front of the engine apart to get at the tensioner.
I walked away from the car, as I was on the borderline of throwing  things and turning the air blue with cusswords and shocking the neighbors.
One step forwards, two steps back.
