Default Really baffling waterpump issue?

Hey all, here's the back-story, let's see if you guys can help me out here.

I'm working with a 1998 legacy outback ltd, ej25d, 138k.

I took the car to my shop this past weekend to do my build. The car did not want to stay idling at all, which is strange, considering it idled like a charm when I picked it up. It hadn't been driven at this point, except onto a trailer and off onto a car lot.
We get the car up onto the lift and proceed with the build (full brakes, rotors, PS pump, forester suspension, rear sway, short shifter and bushings) I was very happy with the way everything was going, and my sister's boyfriend (who's 36, and has done cars his whole life) consoled me by telling me that the idling problem sounded like "bad gas".
At this point, the car is not leaking anything but power steering fluid.
At some point after replacing the power steering pump and reassembling the whole cluster-f*ck of bolts that accompany it and the attached bracket, we start the car and test the power steering (yes, there was fluid, it feels like butter now )
It was at this point that I started to notice a rather large leak (of what looks like water/coolant) coming from the front of the engine, on both the passenger and driver's halves, from what looks like a drain, at the bottom of the engine head. Again, the car doesn't want to stay idling (we had to feed it throttle), but we watch the leak and it eventually reduces to a tiny drip.

Now, this is where it get's really strange. We took the car out for a spin to test everything and break in the brakes, etc. Allow me to say at this point that I've never been happier with the ride in any vehicle I have ever owned- it rode like a dream; almost Acura MDX quality, quite honestly. The only weird thing was that the car would not idle. It didn't overheat, as we watched the gauge religiously, but when we pulled over to put in gas (and seafoam) the car did smoke a bit, from under the hood. With all the fluids on the engine at the time, I wasn't surprised; and again, temp gauge reads normal.

We pull out of the gas station, fairly impressed with the little subaru, and take the long way home, with as many challenges as we could find. Not once did the soob overheat, the power wasn't down (it pulled up a hill in 4th pretty well); but you could not clutch it in for longer than a shift, because the car would die.

We get it back to the shop and park it. It's not leaking anymore fluids and the smoke is significantly lessened this time (at which point I remember that it also has an exhaust leak, so perhaps that could be it?).

I'm headed to school here soon, and I need this car to be up and running somewhere around that time. Can anyone point me in the right direction here?

Thanks

Leaking from the red circled area.




And I think it was a 50/50 mix of coolant and water because whatever it was, one was oily and not mixing with the other. It was not engine oil though, or at least it didn't smell like it.

Well, neither coolant nor water should be oily, so I'm not sure I understand what you're saying there.

What was the coolant level in the radiator and overflow tank before and after these adventures?

The water pump is to the right in your picture, right above the thermostat neck. So it doesn't seem like a waterpump issue. Although I guess it could be leaking from the water pump inside the timing belt cover and then leaking out of the cover at the first convenient spot it finds to leak.

I'd say your best bet is to remove the timing covers (which will require you to remove the crank pulley), reinstall the crank pulley and belts, start 'er up, and see where it's leaking from. Based on what you've described I can't really give you any more advice than that.

Something to think about. You stated that when you put the clutch in it dies. For me my TPS started to go bad and for 2 weeks I could not figure out what was happening, but every time i put in my clutch my rpms would just drop to 0 and the car would die. It was not until the 2 weeks with the problem that a check engine light occured and I was able to remidy the problem by replacing the TPS.

I'm going to clean (or replace) the PCV, and clean the TPS, etc, to check for idling problems.
The real bitch is that I think if I commit to pulling the pully (haha) and I find something severely f*kered down there, it's best to just replace everything isn't it?

(Timingbelt, tensioner, headgasket, gaskets, waterpump, crank seal, etc)

Thanks all
