This is a 1993 manual 240. A small amount of coolant on my garage floor of late, that is dripping down at the juncture between the bell housing and the support extension that goes under the oil pan. It is not coming from the heater return pipe, the heater hoses, or the coolant drain cock. The juncture between head and block appears to be dry, although it's hard the get in there to make sure. At the front end, radiator hoses, thermostat housing, expansion reservoir, etc. are all dry - nothing coming out of the coolant pump breather hole. There is, however, a slight amount of moisture at the coolant pump to head seal when the engine is cold, not while the engine is hot but not running, or while running. It seems hard to imagine that coolant from there would make its way to be rear of the engine. I don't see a moisture track, everything appears to be dry till I get to the bell housing. The loss is so small that I haven't noticed the coolant level in the reservoir going down. I'll tighten the fasteners on the pump and, if that doesn't do it, replace the seal. Meanwhile, any suggestions would be much appreciated.
Thanks,
