I'm going to call today a sad comedy of errors, I honestly can't believe the car made it back home.
So I innocently decided to take my lunch break to pick up a low mile radiator fan at the junk yard (because that's what you do when you have an old miata).
It's pretty far away and I get there and they say its at the other location, closer to my house naturally. No biggie, its nice out and I have taken the opportunity to run autotune on the car.
I get back in the car and it doesn't start well and barely idles, I keep trying...sounds like the fuel pump is running, cut the car off completely and it just keeps running. I jump out to pull the battery cable to stop it and see it's not the fuel pump but my water injection system, running full blast!
It's pumped nearly half the tank at that point into a non running car, filling the intake manifold!
Luckily the fuse is close by and I pull it. It would appear the pressure switch on the system just randomly failed, it was set for 5psi and capped with no air getting to it. Just random bad luck.
Fortunately I have some minor tools because I don't drive this car without them. I remove the intake and drain out a very small amount of liquid...the other 1/2 gallon of liquid is in the intake manifold..
I pull the water meth hose from it and it starts to slowly drip out, drip, not run, drip. I jack up the car on loose gravel to 'assist'. I wait about an hour trying other ways to get it out and then decide to pull the plugs and suck/blow it out that way since there really isn't a good way to drain it, period.
That sort of works, cylinder 4 grabs a good bit and spews it out, the rest remain clear. The intake sits at an angle leaning away from the head which was my saving grace, the vast majority of the liquid was pooled up on the far wall, I know this because I did some
Eventually the junk yard guys tell me I have to leave, no jacking up cars in the lot, don't want them to get confused with junk cars I suppose...
I reluctantly seal it up, knowing there is still liquid in the system. I get it started and slowly let it stumble it's way through the rest, I dip the gas to suck in hopefully manageable amounts and it works! The car runs rough for awhile but eventually clears itself out, it stumbles up the exit hill before a nice painful ride out a cow grate that rattles the car pretty hard.
Next... I get some gas and go through a rough intersection and it sounds like rocks are falling out of the car, I was on gravel so I figured no biggie. A car stops down the road to turn and as I go to slowly accelerate away a very loud part falls from the car, the car behind me gets hit by something but doesn't notice, I figure it was some tool I left in the engine bay. Because I'm cheap, nervous and curious I go back for it... in the busy road I see my supercharger mounting support bar, apparently it vibrated free... I found 1 bolt too.
Then I get to drive the rest of the way home with no cooling fan (it's hot at this point and busy) and a heavy blower being supported by tiny intake manifold bolts.
Suffice to say, the car isn't ready for prime time, I'm going to go through and recheck all the torques and figure out what to do about the water meth controller.
About a 1/2 a gallon...
It's all your fault!
