If u have water in your oil then that's not good you more than likely have a blown head gasket change your oil Fresh Out filter and all and if you get water in your oil again then you have a blown head gasket.

My thoughts exactly. No, those elbows won't allow your coolant to mix with the oil. Since you indicate your Grand Prix is the SE model I'm assuming you have the 3.1L (3100) V6. They do often blow head gaskets. If you have the 3.8L (3800 Series II) V6 it's going to be the intake manifold gaskets. HTH. -Jim


Lower plenum gaskets have blown. Not head gaskets.
