Default Water in Head

I took the driver side valve cover off and noticed that i had water in my head or atleast sitting in the head... i drained the oil to find it to have a milkshake apperance. I took the plugs out of the driver side so they can dry out. i am going to pull the pan tomorow and clean that out.
my question is should i take the head off and make sure there is no water/collant/fluid sitting on top of the pistons? seems like alot of work to me. i was thinking of just changing the oil very often after i clean out the pan and the water will eventually work its way out...
what do ya'll think?

Either a bad head gasket or worst case a cracked head either way you need to get the heads off to check. I see in your profile you have a 88 how many miles. Do not drive it it will not fix itself you can do major damage if you do.

What year is your vette. Sounds like a blown head gasket, water leaking into the oil. Water on top is probably from the oil and water being pumped up there. I would pull both heads.

JMO....Mike Good Luck.

im the one who put the water in the head... well not on purpose, i was spraying down the engine a week or so ago and didnt notice the gaping hole back of the valve cover near the bottom of the intake. im not worried about it happening again just wondering if need to take the head off to get all the water out, or if pulling the pan and changing the oil does the trick
i have a 1988 with 106,000 on it that i am semi restoring

If you know you put the water in there.. then change the oil and bring it up to temp (no load at idle) and change it again.. that should get most of it out.. If your going to drop the pan and clean it up so much the better. but no you dont need to pull the heads. when the engine comes up to temp the water will steam out.

I don't think you need to pull the pan. Drain the contaminated oil, if it has sat for any time at all the oil and water will have separated with the water on the bottom. When the drain plug is pulled water will come out first then oil. If you watch it will be very obvious when the oil starts flowing. When the oil has drained refill with a new filter, run until operating temps are reached, drain while hot if possible. Refill with a new filter.

If you ran the car there is no water sitting on the piston.
