water leak

Thanks guys. I just went out and checked for oil in the motor. The dipstick is clean, the only evidence any water in the motor the valve cover breather above the #1 cylinder had a little muckie on it. the rest were all clean. unlike the last time I checked. last time it was the breather over #2. I was told to smell the water when the motor is running and see if I smell exhaust . havnt tried that yet, will try that today. My heads wernt milled, with 30000 miles on it I am leaning toward intake. Guess I will redo that and check everthing again. could the timing chain cover somehow leak into the motor??? thanks guys. hope you all have a MERRY CHRISTMAS AND A HAPPY NEW YEARS.
