Small block chevy 327 - water in oil. Car hadn't run in 15 years, started it, found oil discolored and foamy. Changed oil, added coolant, restarted. Hard to start didnt want to crank over, smoked blue, moderate amount, Ran 5 minutes max, oil/water sprayed from seal on timing gear cover - checked oil - twice normal amount in pan, all plugs black soot,wet(water).. I suspect head, manifold gaskets. If not gaskets - I need some diagnostic tips to help me find crack. Stock GM aluminum high rise, 10.5:1 comp, RV cam

take out all the spark plugs and put a radiator pressre tester on the radiator and pressurize the system, then inspect each spark plug hole for coolant. you will find out what cylinder or head will need service. How did this car run before sitting? Blue smoke is not good, although it doesnt sound like you have run it long enough to verify any real cyl problems. if its smoking it may be overhaul time. and the complete engin ewill need disassembly.
