Since there is no tool section on FEOA im going to ask it here.
What it the name of the tool used to pressurize (air tool) the piston chamber to prevent valves from falling down to the piston when replacing valve stems. I knew the name but I'm clueless now.

Its a "spark plug thread adapter". Here is a website where you can buy the kit: http://www.summitracing.com/parts/MOR-62385/
And here is the large image of it:

I havent used it with my Escorts though. If it wont fit down into the deep spark plug hole, you could buy a copule of those 'anti-fouling' spark plug adapters, that were once used on old cars to keep the spark plugs from fouling. That might extend the 'plug threads' up out of the hole. I still see them for sale in some of the auto parts places, in those bubble-wrap product lines like the 'HELP' products.
You also might be able to get one of those compression testers that thread into the plug hole and have a length of hose. That would work, if you were able to unscrew the pressure gauge and the one-way valve next to it. (The valve is one-way the wrong way for pressurizing the combustion chamber).

I have read in service manuals where it told you to postion the piston at top dead center (very carefully) while workiing on getting valve springs off. But if its not exactly at TDC, the air pressure will push the piston down. So I start with the piston part way down, and let the air pressure push it the rest of the way. I dont like to have the crankshaft thrash around when I dont need to.

I have a snap on compression guage and you simply have to remove the one way schrader valve that is inline and use shop air to hold the valves closed.
