Now I think there may be a problem with the safety valve. The stem was badly oxidized and had to remove a lot of green residue from it. The gasket is new and the tension is good but it might be leaking steam (and water?) through the valve stem. I'll test that tomorrow and make a new stem if necessary. Insufficient steam pressure may lead to the water intake in the engine.
