    Really hard to install the head gasket on backwards. What about the base gaskets? Are the tabs to the exhaust side? If those are backwards it will definitely get water in the cylinders.

    As far as I'm concerned the acc pumps only ever cause grief. I always just take them off. The lack of squirt means either the check valve is sticky or the acc pump itself just isn't working.
