drip drip drip

I am well aware that my vehicle is 30 years old and is going to drip a little oil. I recently have developed a small coolant leak though that I can't seem to stop or locate. It drips off the front of the oil pan on the drivers side. It is a very slight drip that leaves a small mark on the ground. Two qusetions;(1)Where to search for the leak and (2)Should I be concerned about a cracked block? Thanks in advance.

I would check the bottom radiator hose/hose clamp and the weep hole on the bottom of the water pump. I had a bad pump that started to weep and the leak appeared in almost the same spot you describe.

There are also 2 weep tubes in the timing cover at the water passages. If the water passages get eaten away, the leak is directed outside instead of to the oil pan.

Also, check all your core plugs, including the small ones in the head, head to intake joint, the thermostat housing, CTO switch, temp sensor, and bypass hose.
