Great! Also great to see a solution for a problem. Only @ a 1/4 of posters report resolution. O.

If you remove the egr unit, you can remove the studs that go into the IM and will give you working room.At least for the top one. That brass nut LOVES to round off. Everytime I have to do one it's an adventure. Wound up using the above procedure and a pipe wrench to get that one off. Didn't have to do the lower(lucky me) as I was only removing the IM. O.

You also need a torque wrench for reinstallation. O.

Don't know the actual differences, however you can reverse lookup and check. If you click on a part in opposed forces, you will then see a usage info link. Clicking that will show all models that part fits. Otherwise you can go to a Suby vendor website and go to the particular part and without using any filters, you can see the part number for all Subys, then you can narrow your search. O.

Think you may be misguided here. Bosch O2 sensors are fine. They come a lot as OEM units. In addition Bosch is the originator of the O2 sensor, not a fly by night mfg. O.

90% of the time a 420 is caused by a bad front sensor. I would google this code specifically for Subaru and go through those checks first. Cats can go bad, but usually they last they life of the car. If it was me, I'd replace the front sensor. O.

They changed. Looking at them side by side you'll see. O.

Yes it will. O.

From your photo I would keep an eye on that water bypass pipe. It has a tendency to rust through at the T which goes to the TB. O.

If the rear main is not really leaking, leave it. A little seepage is ok. O.

99 Forester has the 2.5SOHC and as such the HG's will leak externally in this series. SOA's "fix" was their "conditioner" (read stop leak). Will last an indeterminate mileage n this condition. Just watch coolant levels and signs of seepage. Unless you have nothing "better" to do, I'd leave it alone. I'm retired, so when I pull an engine I tend to do everything, for I have nothing but time and little sense. O.

Tailpipe. O.

Looking here should help. http://opposedforces.com/parts/impreza/ O.

]Probably pump. Check voltage at pump terminals. If 12 v, then pump is problem Alternatively you can jump pump to battery and see if it works. Easy fix in either case. Can't help with seat tho. Attached is schematic for seat and a link to FSM for your car. http://www.main.experiencetherave.com/subaru_manual_scans/ Power Seat System.pdf O.

Those screws are torx. T25 or T27 IIRC. O.

Guess you missed the part where the post was from 2009! O.

No. O.

Swap plug with any that will reach. Clear code. If code returns to the other cylinder then it is the wire. If not it could be either a coil/injector. Reistance values for plug wires is 5.12 - 12.34 Kohms. See attached for coil check. O. Service Procedure Ignition Coil.pdf

Suby oil pressure mil is set too low for comfort.3/4 psi IIRC. We can only keep a check on our level. If the level is good and you are getting flashing, then something may be up with the pump/the sensor.. In case you didn't find it, the oil system section starts on p 341 of the pdf I sent a link to. O.

Need to post more info. 2.5/3.0. In either case, here is a link to 2008 fsm. You'll have to look. Its a big pdf (5800+ pages), but it has all models. http://people.csail.mit.edu/ilh/vacation/ O.

After the pinch bolt was opened a little, used PB, then put castle nut back on but not all the way tight, and finally a 4 ft spoon bar. Pryed it right out. On a previous ball joint,the arm pried down, so I used a chisel at an angle on the BJ to break the rust loose, then reattched castle nut some then pried. O.

Can't comment on price, but I would be concerned about the rear tire wear. Did the po not be concerned that this was an awd car and should have replaced all four tires at once? Therefore this car has been consistently run with mismatched tires. Just something to consider. O.

There is an auto store item called guaranteed to pass or something like that for emissions testing. Check your local stores. O.

Part of the self check. About 4 or 5 times. If it flashes 16 times. Then there is a some fault., O.

^+1 You can usually get a set of WRX 16' rims for cheap from seller on NASIOC. Then any tire you decide on. O.
