On a Chevy, the only areas that water can enter the oil are either a cracked
block( not likely), leaking intake water crossover, Or heads, cracks or
gaskets ,most head cracks and gasket leaks would cause combustion gases to
enter the water or water to enter the combustion chambers. Another source of
water in the oil would be an raw water cooled external engine oil cooler.
Another thing could be the thermostat, running without one can build up
condensation from water vapor that never gets boiled out unless you get the
oil hot enought. Anyway good luck.

Ron,
Thanks again for the reply. There is no oil cooler and there is a thermostat
and engine temp usually runs about 140 on the gauge. Not sure what happened
and not real confident that changing the head gaskets will "fix" anything.
Hopefully the problem goes away. In hindsight, I should have changed the oil
and filter once first to see if it went away.........
