I like this better than what I came up with. It will be easier to find the parts and assembly will also be easier since none of the initial parts need to be modified. As long as one is careful not to draw the water or oil into the engine, it will also be easier to use. Although there always seems to be a better way to do something, this seems as good and simple as it can get. No more excuses for not knowing where TDC is.

You can get an air hold, essentially a spark plug hole adapter that goes on a compressed air hose, for about $6 at NAPA. It's used to hold a valve in place while you change the valve seals. You can use it to find TDC by putting it in the plug hole, running a tube to it and putting the end in a jar of water or oil. Turn the engine slowly until the point where the bubbles stop and the water just starts to go up the tube. That's TDC.

Steve: Please don't think your cool invention wasn't appreciated by those of us at Paduca... I for one grabbed one and plan on using it to find TDC prior to re-installing my CAS...
