Coolant leak

The otherday the 190e 2.6 started severly leaking coolant. Appears to be leaking from somewhere under the Intake Manifold, but i can not see up there. Is there any waterlines that run around there? or is this possibly a freeze plug, head gasket or worse?

When the car is off, no leak... warming up, its a drip drip drip... fully warmed, a steady stream that runs down from somewhere, and then flows off the center of the oil pan...

any ideas?

thanks

I think the return line from the heater core, back to the coolant pump runs on the intake side of the block.

MTI... thanks! that is positive news... I have yet been able to get under it and jack the car up to take a look. If at all possible, i would like to try to fix this myself... but if there was to be no coolant lines under the intake, i was just going to take the car in, or scrap it becuase i would imagine its not worth anything if something like a head gasket was blown.

Pretty sure the return line is on the intake side, since the heater core is the same as on the 2.3L, the exit fitting would place the return line on the left side of the engine bay.
