A plugged or misrouted PCV system can cause water condensation in the crankcase. Have you checked the coolant level in the radiator? Not the plastic recovery tank. If the dealer messed up the intake gasket, take it back. Especially if you were not having this issue before the repair. HTH. -Jim

The level in the radiator is what I was referring to, the dealer won't take it back he offered me a little cash that's it, its just confusing I've never had a Chevy do this to me! What is the correct way the PCV system is put together?

Typically the PCV valve plugs into the valve cover with a hose that goes to the intake manifold. Then there's another hose going from the other valve cover to the air cleaner assembly. HTH. - Jim

PCV valve is new and routed correctly but still having the same problem.

Are you absolutely certain that the coolant level isn't dropping in the radiator? -Jim

Positive!! I've never seen anything like this before.

Me either. The only 3 ways I know of for water to enter the crankcase are a blown head gasket, bad intake gasket (you'd be losing antifreeze) or condensation from a faulty PCV system. I'll have to do some research into this one. If you find the answer before me, please let us know. -Jim

Did they change your oil twice as part of the intake gasket repair? If not they may not have got all the antifreeze out of the crankcase. Is this possible? HTH. -Jim
