Hmm. I'm beginning to feel some slight amount of hope here. Negative to the above suggested rad cap test (thanks, CrazyLarry) and its definitely clear, not green. I should add that the ecu code was 55 so no hints there, and I cleaned the MAF and connector.

Yes, the engine still runs smooth. I left it running in the driveway for about ten minutes (jumping my Z) which is how I discovered the water coming out the exhaust. That said, it did die at a light a couple times on the way home later that night... I'll try the rad cap suggestion. Thanks!

Hi everyone, I'm afraid my first post here is a sad one. I'm looking for confirmation of the inevitable: Can anyone think of any reason why I would have water dripping out my exhaust other than blown head gasket? No, the oil doesn't seem particularly chocolate milky. That said, I got a low oil pressure warning while driving and after (eventually) pulling over and walking to the nearest gas station, added about two and a half quarts. Yes, I did continue driving for a while after the low oil pressure warning flickered. Yes, I am an idiot. What am I likely to have to pay to have my Datsun repair guy pull the head and repair? Anyone?
