No, I actually saw it running off the oil filter and cooler and
forming the puddle on the ground. I did just have a thought about
the idea of stopping the engine after highway driving and a coolant
temp spike occurring. Where is it hottest? In the heads. Could
the heat and pressure buildup have cause a small stream to spray out
of a head gasket? Seems like it would have been easier for the
pressure to come out the cap. I do get some very small cold weather
drips from the head gaskets.
