94 Labaron mysterious anti freeze leak

My 94 Labaron is leaking coolent. The radiator was replaced since a leak in it prevented a pressure test. After repair a pressure test revealed coolent near the drivers side of the engin. Suspecting a rotten pipe at the manifold my mechanic replaced what I believe were 2- O rings and pipe near the manifold. After pressure testing it continues to leak but it is impossible to see where. My mechanic does not think it is the water pump and advises bringing the car to a machine shop to see if the head or block is leaking. I am not a mechanic and all this guessing is getting very expensive. Any of you have similar problems or better solutions?

You may want to check your heater core and the associated hoses and piping.

Thanks,

Will do
