RE: heater valves
I got a reply in the Yahoo heckflosse group and it worked great. All credit here to Walter Wiebach for his homemade puller.
I had my whole heater assembly out but this can be done in the car. Just be warned you will be releasing water from the sludgy bowels of hell so be prepared to catch it. Drain the cooling system, Its time for a flush anyway. There will still be water in the heater radiators. I had most of my cooling system out (radiator and all the hoses except to the injector pump/drivers heater) when I opened the clamps at the heaters. It was still a mess. Supplies:
3/4" female to sweat copper pipe adapter, long 4mm .7 allen screw, a 4mm nut, and washers to adapt from the nut to the sweat side of the pipe adapter ( I used 2 small 4mm washers and 2 fender washers).Unscrew the arm with the cable at the valve. You may want to mark the core to valve housing position for easier reinsertion. The threaded side of the copper pipe adapter fits over the valve. Screw the nut all the way onto the allen screw and slip on the washers. Going throught the pipe adapter, screw this assembly to the hole in the valve. Using an allen wrench to hold the allen screw in position, use an open ended wrench to turn the nut. This will gradually pull the valve core as the nut travels down the screw. Repeat with the other heater. Mine were stuck in hard enough that the washers bent. Replace the "o" ring, wipe down with waterproof lubricant, reinsert the cores and you've got working valves which = heat.
I'll write this up and post it with the pics I took while I did it at 220SEb.com this week.
