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.........


Yes, and no. If the water "disappeared", you would have saved some
money, but that is not likely. If it came back, that would mean that
you were again running water through your bearings. Not a good idea.

I have seen heads warp just enough, when overheated, to allow leaks,
with no other obvious damage to gaskets, etc.

FWIW, I think you did the right thing.

Thanks for the supportting comments. I think it was probably the right thing
to do also, but hate to think an oil change could have fixed it. After
thinking about it, there was noticable drops/little puddles of water on top of
the right head (just noticed the emulsified oil in the left head), so it was
probably leaking.

I get the heads back today and the gaskets I ordered are also supposed to be in
today. Hope to have it running for the weekend.

Thanks to all who posted!
