"Are there any freeze plugs in the back of block, hidden by the bell housing, that may have started leaking?"
Not in the back but on the side.

The last one, passenger side, by the drain cock, has a block heater installed. After adding water to the reservoir I checked the hoses - no leaks. Then noticed water coming out from under the exhaust manifold. Traced it to the block heater.

Removed the blocker heater (#3 Robertson) and found that the "wing" in the back, made of brass(?), was soft and cracked. Metal fatigue? And had loosened allowing water to spew out. (The block heater is clamped against the engine with a "toggle bolt anchor" system as used in hollow walls.)

Hmm. So should I try using a wing from a toggle bolt or go buy a new block heater? Temporarily?
