I have a '88 260e, M103 engine, with 189,000 miles that is leaking coolant from head gasket area of the passenger front of the engine (over the no.1 cylinder). I saw many threads on this forum about oil leaking from the head gasket but never coolant leaking externally from the head gasket. The oil and coolant in my car are both clean - no cross contamination.

I replaced a leaky water pump last summer and this leak is different...coming from the opposite side of the engine. I can't imagine what, except for the head gasket, could be leaking at this location.
