I had to throw away a Blue Thunder intake manifold because it had a pore inside one of the pushrod holes and was seeping water inside the engine.
I discovered it with the valve cover off and the engine running.
When trying to weld a tube inside the hole the water came out somewhere else, and if I soldered that pore shut the water found some other way out into the engine.
If you have a Dove you may have an aluminum casting defect like I had.
