(Hey, that's nothing new in Usenet, but it's unusual to have someone *admit* it directly, no?). About ten years back, my folks had a Cadillac, with the 4.1 Liter aluminum engine. It had/has a design flaw, in that the block is aluminum, the sleeves are steel, and they sealed between them with an O-ring. That o-ring breaks down due to the thermal cycling & differential expansion of the two materials, allowing (among other problems) leakage of coolant into the oil. G.M., in their inifinite wisdom, decided that one of the field-fixes for this was to install stop-leak powder. This was one of their "hidden recalls", where they'd just do the semi-fix if you brought the car in for something else, and they'd eventually pay for the real fix if you happened to know that they were supposed to, and screamed loud enough. So, my folks got their car back after some routine service, and noticed that new coolant, and stop-leak, were on the bill. Odd, but they didn't pursue it. (probably, didn't notice until we started looking back through the paperwork after the camshaft rounded off). That autumn/winter, the heater didn't work. The independant garage that changed the heater core, showed us that it was plugged with stop-leak. Still got the heater core around my folks' house somewhere. Of course, at the time, they didn't know about the hidden recall, and hadn't made the connection between that, the dealership, and the heater failing (it was bought used, so I suppose they just suspected a previous owner or whatever). Anyway, GM BS aside, the point remains that, in this case, it plugged the heater matrix. Perhaps formulations have changed in the last decade or so since this happened, and if so, I'd love to know about it, as I'm quite willing to be convinced that it's no longer the case. Dave Hinz
