1934 V8 flathead engine block water leak

[verrece]

I found various small drops that it's coming out from the engine block in different places, just above the starter. Could any give me any idea what is going on and how fix it?
How about engine block and coolant leak repair products?
Please look the attached Photo

Try Barrs leak, or alumaseal radiator additive. Either one should stop those leaks.

yikes... that looks like spider cracks in the block seeping coolant. Hows your oil look?

maybe... clean the area real well and smear some jd weld in the cracks. Add some bars leaks too? Guess it depends on what you what out of this engine.

It looks (to me at least) that it is time to find another engine. That one is only temporary.

I'm with blue bell, time to start finding a replacement block and eventually rebuild the rest of the engine. Do you drive it very much or very far?? Doesn't look as if its leaking that much and if there is no water in your oil.....drive it till the replacement block is ready and you have the time and $$$$$ to make the switch!!!!

The 34 (as well as many other years) flat head engines have four Welsh plugs in the block surface, that are covered by the oil pan. You can see the plugs in the photo below. It is VERY, VERY possible the 3/4" diameter metal welsh plugs have rusted through and are now leaking coolant. Sometimes the leaks go inside the oil pan and into the engine oil some leak outward. The plugs can be inspected and changed with the engine in the car, but the oil pan has to be removed. There is OFTEN a lot of original foundry sand still left in the rear of the block that can be removed with the two rear plugs are removed. If you do not see the source of the coolant leak when you clean the coolant staining, remove the oil pan.

Those leaks are well above the core plugs. I agree that it is time for a new block. Looks like the whole bottom of the water jacket is beginning to rust through. I bet if you poked that area with a pick, you'd go right through the jacket.

Dear all, I live in Argentina and here is very difficult to find a brand new block or another engine.
Tinker. Rockfla and Terry OH, fortunately there is no water in oil.

If that is the case just put some stop leak in it and keep driving it.
