I have e-mailed DD about it, but I like to have lots of opinions when I have a potentially serious problem. I sat last night just staring at the block for almost an hour, and I just can't figure out how I could get coolant-stains on the block where they are, I'm really stumped. If there is a pinhole leak on the baseplate as I suspect, why does the stain come up onto the top/front face of the block? Same thing applies if the leak is in the solder joint.
Also, the pump is on 24/7, even if the system is off. I don't have a relay or anything else, and still follow the (possibly proven wrong when I wasn't watching/reading the boards) rule that says these little aquarium pumps last longer if they aren't cycled on/off all the time.
Anyways, when I get home today (writing this from work) I'm going to tear it all apart and get a closer look - I'll update the thread if/when I find out anything.
