BSOD2600

I'm going to school in Klamath Falls, which is around 4300ft. I've noticed a few things about how my car changes with the elevation: 1) When I romp on the gas, typically the car switches into 'power mode' and takes off. When in kfalls, this does not happen. 2) There is a weird buzzing/humming sound thats most noticeable around 2-3.5K (until the tranny shifts and the rpms drop). It changes with speed. Initially I thought it was some problem with my transmission (I'm pretty sure its slipping or something anyways), but this weekend I drove back to a sea level city and I don't hear the sound anymore (or it's still there just not really noticeable anymore). 3) The engine often revs up to 2K when in drive or reverse to get the car moving. Then all of a sudden, it engages and the car jerks in the direction. This a sign there are problems with the transmission? Yea, this isn't an elevation issue since it happens all the time. The transmission was swapped out with another 89K mile AT 2 weeks ago. 4) Obvious lack of power compared to sea level -- yea, I realize this is normal because of the elevation. Are there some changes the ECU makes based on the MAP sensor or something?

Yes, I hear it all the time. Since I've had the car, it hasn't rained, so I really doubt there is any water caught in my door(s).

It seems all these tips apply to NA engines and not turbo. I don't have a bleed screw on my 94 turbo legacy. The coolant tank on top of the engine is full and the overflow tank is partially full. Yet, I still hear a water sound (typically during acceleration) coming from the dash area. My car doesn't overheat, so I guess it's all good. Just bothers me hearing it often.

Yea, well my transmission WAS just replaced last weekend. Guess they were sloppy and didn't replace the seals?

I changed the oil tonight -- WOW, talk about being dirty for only being in there for 24 hours. The clicking still hasn't returned so I'm calling SeaFoam the cure. Guess that SeaFoam cleaned some crap up. While I was under there last night and tonight, I noticed I've got an oil leak from somewhere. Sprayed some cleaner on the whole area, let it soak and then hosed it off. Here is what it looks like before (no after pics because it's too dark now):

For my lunch break today, I drove ~2 mi to Schucks to pick up some SeaFoam and more oil. The entire way it was clicking. Dumped in half the can of seafoam into the oil and then drove ~1 mi to Kid Valley for lunch (mmmmm!). Returning to work, I didn’t hear the clicking anymore! I won’t called it fixed just yet, but it’s sounding good. Got to do some errands tonight and then I’ll change the oil again. My 94 turbo legacy came with a 93 manual which states it takes 4.2 Qts / 4L of oil – it still should be the same for my 94, right?

This morning it was still making the clicking noise. I took a long screwdriver and placed it on each cylinder. The sound was obviously coming from the back right one (is that the #2?). On my way to work, I stopped by two Subaru mechanic shops. The first one was Smart Service (http://www.smart-service.com). A mechanic listened to the noise and told me it was most likely the lifter. Said it might be stuck / not fully opening. Said I could try running some engine cleaner stuff in the oil to see if that fixes it, if not then he would have to take it apart and clean them. The other mechanic place I took it to was Suburb Service. Once again, the mechanic said it was lifter noise. She also said that it could be the oil pump that could be going out (and putting air in the oil?) or the rubber ring around some hold was sucking itself in. Both said that it wouldn’t be bad to drive the 500 miles to school – I’d notice the sound getting louder, worse gas mileage and a rougher idle. Since I drove to work around 8am, no auto store was open. During lunch, I plan to run out and get some Seafoam to put in the oil. *Hopefully* that’ll fix the problem. If not, then I plan on driving to school and taking it to a mechanic the first week. Anyone know a reputable mechanic in Klamath Falls, OR?

Lets say it's a valve lifter -- is that something that can be fixed easily or requires tearing the engine apart/out?

A definite yes! I'm revving the engine with the hood open in that sound clip when the clicking gets faster. If it's clicking tomorrow morning, I'll try disconnecting each spark plug and see how that changes the sound. Guess before work, I'll try to take it to a Subaru mechanic and have him give me a guestimate on what the problem is. I don't know about power loss -- I've just gotten this car so not used to its characteristics yet. Plus it's an AT and I've only previously owned MT cars, so even more difference.

I've only owned the car (94 legacy turbo touring wagon) for about ~150 miles (since Monday). It's got 149K miles and the transmission was just replaced with a 89K one, AT. Anyways yesterday I got home around 5. As I leave for CarToys (wiring harness...again), about an hour later. I notice a new clicking sound coming from the engine, that I've never heard before. As I rev the engine it gets faster. Anyways the entire ~15 mile trip, it's clicking away. 3 blocks away from my house, as randomly as it came, it went away. I did check the oil last night and it was above full. This morning I don't recall hearing the clicking sound. On the way back from work, I heard the clicking sound again. Changed the oil (with 10W-30) and it still clicks! Drove back to a bit but it never went away. hereHere is a crappy sound recording of it. Thoughts? I realize this is a really vague question with little technical information, but what could that be? Last thing I need before leaving for college is to have my new car dying. I was planning on leaving this Saturday too.
