Not a new one (I wish!) used one from eBay, they cleaned it and spray painted it, you can see it, but it works nicely (compared to my old one)
The question about the screw: holding each coolant and air inlet/outlet is a flat base with a screw hole, through this hole is a phillip head small screw that attaches to the body of the valve in order to fasten the inlet/outlet tube against the body of the ISC, my question was that if it possible to remove these three small phillip head screws so I can re-position the pipes. However, I then noticed that the ISC they sold me is not for my car, I believe the difference is that the one I bought from eBay is for the 8v.
Also, while inspecting my old ISC yesterday I looked into the hole where the piston shows (where one can see the spring around the piston) and saw a little piece of broken rubber (from the seat maybe? ouch)
What I did next was to hold isc in my hand, put two leads on its connector and start blowing through the top hose and applying 12 v (I kept adjusting the allen head screw until I was in the border line where 12 v can move the piston and the least amount of air is leaked by blowing through when no power is applied to the isc)
I then adjusted air bleed screw close to 600 rpm with ISC electrically unplugged and when I plugged it RPM's went up around 45 rpm more but it never got to 800 (HL off)
I did not compare coil resistance between both valves. I have access to a nice scope but honestly this is a tool I haven't used myself before. I will have to go online and do research and start playing with it until I understand it better. I'll take a look at duty cycle on ISC's FSM
