Two last questions (I hope). I'm going to use freon cans and was wondering how good the side mount can tap as shown in the starter kit (above) was.
Also will the dye hurt the Porsche AC system?

Having the dye added to the system is pretty much SOP today, because:
Say for example you are testing for leaks with an electronic sniffer at a connection(s) or component(s) on the high side, and the system pressure is (for example) 225 psi and the sniffer does not detect a leak. Then a few days later it is much hotter outside (ambient) and the high side pressure jumps near 300, chances are any small or potential leak point will be more likely to push out refrigerant (and the dye). Dye does not always show up at leak small points, but for the cost and simple procedure it is well worth the effort.
Avoid any refrigerant additives such as
"leak sealer" or "revitalizers" .
With respect to charging with small cans:
a) Know the capacity of the can, 12 oz or 16 oz.
b) purge the air from cans hose before connecting to the system
c) Wear safety glasses and don't expose R12 to open flames or heat ranges of the same.
d) Remember that most of the retail "starter" kits are rather inexpensive, so you get what you pay for. Insure the seal is attached to the tap port that contacts the can, and make sure the device that punctures the can is retracted before you attach the can. If you don't have a formal refrigerant service gauge set then find a friend that has one and who has done the procedure before (hopefully more than one time) to guide you.
We can go on to mention other things you are suppose to know before you start the procedures, however most of them have been covered already in other posts......
soooooooooooo READ before you start.
