As I pulled off at my exit and came to a stop, the temp. gauge ran up almost instantly to 260 or so, and started missing like mad. I tried to nurse it home and put it straight in the garage, but it died at the first stoplight on the overpass, about a mile from home. And dammit, I had my dog in the car with me.

It'* a good thing I did! At 162K miles, the lower gaskets were deteriorating also. It was pretty dry though, thank god. (The topside of the lower intake was FULL of antifreeze.)

Yeah. So anyway, I popped the hood and noticed that my overflow reservoir was empty, checked the radiator, yep, that'* empty too. My car dumped nearly a full system'* worth of coolant in less than half an hour -- I had stopped for gas prior to all this happening and checked all my fluids. I was afraid that the intake manifold had given way, since I didn't see any steam or smell any coolant from under the hood on the way home, but I figured that it couldn't hurt to refill the system and try and start her again after she cooled down. Of course, I'd left my jug of coolant mix in my garage at home, so the friendly cops watched my car (and dog) while I ran to the nearest gas station.

I come back with two gallons of premixed antifreeze, go into my trunk to get my funnel -- oh yeah, it'* sitting on top of that jug of antifreeze in my garage. Dammit. The wind is really whipping on top of that overpass, and I can't pour from the jug into the radiator to save my life. Coolant everywhere. So I use my hand.

After the radiator was full, I try and crank her up; I get about a second'* worth of cranking followed by silence (except for the starter burning up). Hydrolocked. Dammit. Apparently, one or more of the cylinders was FULL of antifreeze.
So my car is sitting at my friendly neighborhood garage as we (I) speak (type). Thankfully he gave the same diagnosis I suspected, so I dropped off all my parts (plenum, gaskets, etc) with him and let him at it. I don't have time to try and fix it myself -- plus, if I didn't fix it, I'd have to pay *another* wrecker to tow it from my garage to his garage. To hell with that.

My day'* been an adventure. And it'* only two o'clock.

How'* your day been? :P
