I was talking to a guy with a 53 chev and a 235 , seems his engine would would have water in the oil after being parked for some time outside.
The leak was traced to a leak around some fitting on the hood that allowed water to drip on the valve cover which had 4 slots in the top I guess for breathing purposes.
He replaced valve cover which solved the problem.
This might not be news to some , but it was to me!
