Swapping in a used ECU shouldn't be a big deal on a 2007. I tried this on my 2008 Forester and had no issues (also didn't solve the problem so I now have a spare). I'm not sure about that generation Outback, but it was plug and play for my Forester.

Yes plugs are just a few thousand miles old and I just put new NGK wires on it. Just replaced both O2 sensors with Denso units as well.

Yes, OEM alternators are pricy but worth it compared to other rebuilts. Other rebuilders only replace defective parts but Subaru replaces anything that might fail so it's as good as a new one. I recall pricing one for my 2005 Impreza and it was around the same price as you found. I kjust put an OEM on my 2000 Outback and luckily for that year it was only around $250

The reservoir has never overflowed nor has this car ever had an air bubbles in the reservoir with the engine running (I had two newer Foresters with internal headgasket leaks so I knew what to check for on this one)

I figured it out the other day. I took another look at the heater hoses and there was wet coolant residue at the heater core ends of the hoses. The clamps weren't super tight, so i tightened them down (I replaced the heater hoses and used new clamps 5 years ago). I figured I was pushing on the heater hoses when accessing the transmission dipstick when I was checking the ATF level, and the loose clamps let some coolant leak out when the hoses were pushed on. I ran the car and even pushed on the heater hoses, but the connections to the heater core are still dry.

Funny thing that I started and warmed it up a couple times after and no leak at all. I found the radiator was full but the coolant overflow reservoir was empty when it was cold again.

I checking over the 2003 Forester in the garage, and shut it off after checking automatic transmission fluid level. I heard a dripping sound from underneath and saw a small puddle under the transmission pan. I put it up on Jack stands and got underneath, but the dripping had stopped. I confirmed it was engine coolant but looking up underneath, I couldn’t determine where it came from. My first thought was from a heater hose, since it was from that general area, but both heater hoses were clean and dry (they were replaced 5 years ago). Also no indication of leaking from the heater core. Not sure where else to look for coolant leaks near the rear of the engine. Are these are any other small coolant hoses on the EJ251 engine? I recall my old EJ22 had a small coolant hose that ran to the IACV. Not sure where else to look for coolant leak from that part of the car.

Last year, I bought my father's well kept, low mileage 2000 Outback Limited with automatic transmission and only 70K miles. The car runs and drives great, however acceleration seems laggy for an EJ25 4EAT Subaru, especially accelerating up hills. I've owned a number of other Subaru's of this vintage and none were as laggy, including my old EJ22 '98 Legacy. My '03 Forester with 250K miles and the same EJ251 engine, 4EAT transmission, and 4.11 drive ratio seems much peppier. I know the Outback weighs several hundred pounds more than the Forester, but I can't believe that would be make noticeable difference. I wish there was an inexpensive way to get a little more performance from this car. Too bad the power mode hack for 2nd gen Legacy's can't be done on this car (that only applied to Phase 1 4EAT's), and Sport mode didn't come out until 2005. I can see why the H6 was such a popular option for this model when it came out in 2001.

I had two '05 Outback Sports which I miss driving now. I believe there are a lot of aftermarket headlight options, including projectors to run LED/ HID bulbs in. Fun to drive cars and I got close to 30 MPG to boot. The '05 engine was a bit of an oddball too, as it was the first year for the EJ253, but starting in '06 it had variable valve timing. The '05 motor was solid as a rock in both of mine.

On my 2021 Crosstrek I just make it a habit to push the button on the dash to turn it off every time I drive the car, as I find this feature very annoying.

Sounds like you've done all the common fixes. I've hsad these codes on my 2008 Forester and the 2006 I used to have. For me, the oil control valve did the trick. I believe they are sensitive to oil levels, so an oil or change or two might help

I checked but the belt shroud doesn’t come in contact with power steering hoses at any point

I have a low mileage (68K mile) 2000 Outback Limited that I recently acquired from my Dad. I recently replaced the alternator, and the following week, I noticed occasional vibration when turning the steering wheel at low speeds. The first thing I suspected was drive belt tension since I had just removed and reinstalled the belt when I replaced the alternator. Tightening the belt seemed to make it worse, and backing off the belt tension seemed to alleviate the vibration, but I still feel it occasionally. It also doesn't matter if the vehicle is moving or not and it while shake pretty well when moving the steering when parked in the garage. It will shake often but not all the time. I'm suspecting something with the power steering pump- could it need a good power steering fluid flush (power steering fluid level is good), or is the pump itself at fault?

Thr headlights on my 2003 Forester are yellowing like most (I polish them periodically to remove it) but now the passengers side is leaking and getting moisture inside, so I think it’s time to replace them. Are there any good aftermarket brands that would be durable enough not to leak or yellow for a few years? I’d love to find a set of projectors, but it appears that they aren’t mass produced for the 2003- 2005 Forester, other than finding a set of lights retrofitted as projectors, but I don’t intend $1,000 for a set of headlight housings, so likely want a set of good aftermarket housings that will last awhile. .

That makes sense since a rod knock with theoretically occur with each crankshaft revolution, but a valve with too much clearance will only open every other crankshaft revolution, so only half as frequent. My mechanic weighed in that is sounds like valvetrain to him as well.
