COOLANT LEAK

1995 Isuzu Trooper • 375,000 miles

My trooper is leaking coolant near the rear of the engine. I have replaced all coolant hoses, and the o-rings on the tube running under the manifold, along with all manifold gaskets. With the vehicle on jack-stands in the front, as I pour in coolant, it runs out almost as fast as I put it in. What could be leaking?

Can't really see it from here. To be running out that fast I'd first suspect a core plug has corroded through or popped out. There's typically two or three on each side of the engine block.
