Subaru Crew Problems & Solutions

    The baking soda was the part I was looking for. The dealer called it a science project.

    They put the car on their computer and said that my misfire code could be from oil leaking into the spark plug(I did not change the seals in the tube). The spark plug was not tight. And the valves could be sticking (I will try some more Lucas, this time on the next six fill-ups). There was some oil pooling on top of the engine (they said I did not tighten the head gasket properly).

    The other things on this laundry list: Fuel Service, Battery Service, Cat Converter (P0420), O2 sensors, power steering rack boots, coolant service, and fuel filter. If they did all this work it would come to $3738.

    They were going to charge me $52.70 to replace the driver side headlight. I did for $9.99.

    And as I was leaving a salesmen handed me a card. With 302,823 why should I get rid of it now. 400K here I come.
  • Wow- 303K! That's music to my aged ears; I was planning on 200K for my nearly new Forester- maybe I should revise that to 300K? (unless I croak first, of course, in which case my daughter will no doubt take it over)

    Quite an interesting note in a car advice page in the Melbourne Herald Sun today. Subaru Australia explained to them why they recommend the use of a fuel additive on a regular basis. They claim that fuel additives in some fuels result in carbon flakes delaminating from the cylinder walls when the engine cools. In a conventional engine this is not a severe problem as the carbon flaes fall onto the top of the piston and then discharge through exhaust once engine is running. However in a horizontally opposed engine (ie boxer such as Subaru), the flakes of carbon can lodge across the exhaust valves, resulting in the exhaust staying open. thus the engine runs rough until it clears the carbon flakes, if it can be stared at all

    This can also result in flooding of the engine and wet plugs. Apparently, flooding self clears after 12-24 hours when fuel evaporates off the plugs.

    Interesting if true.

    Wow, you are well past the quarter million mile club. Sweet.

    Yeah, it could be due to leaking oil I suppose. That tends to be caused by the inner seal on the valve cover allowing oil to leak into the plug cavity. The wire boots hold that oil in there and it can pool up. Mine did that on one cylinder before the second time I pulled the engine out, but I never had misfire problems due to it. I suppose if the oil found its way onto the plug itself, that could have happened.

    I hope it is not the valves sticking. Otherwise, you could be in for another run pulling the head(s).

    I still lament the loss of my Outback. I would surely be close to 300K by now. :cry:

    Dan at the Subaru dealership said that the spark plugs were not tight enough, so oil could work its way in with the engine cold. After it got hot it sealed up, that may explain misfire cold and running smooth after half an hour.

    I am using Lucas for the next 6 fillup for the sticking valves.

    Well, best of luck to you for some smooth running! With all the work you have put into that car over the last many months, you certainly deserve to enjoy some more trouble-free miles out of it!
  • Well, I did it to my '99 Forester. At a gas station I banged the right rear taillight into the metal post protecting the gas pump. The lenses are smashed, but all lights work. I must replace this before the rainy season starts. The local dealer service dept. is quoting me $250. Can anyone suggest alternative places to find taillight assemblies for less$$? :(

  • xwesxxwesx Fairbanks, AlaskaPosts: 8,391
    Yes. I looked up a couple places real quick, both of which were at least 50% less than $250! lists it for $114.26.

    Rock Auto, which I have used and has great service, great prices, and good shipping rates, has it for $102.79.

    That kind of stuff is bound to happen sooner or later.... :cry:
  • I have a 2001 Forester with AT and I'm having a problem with my key getting stuck in the ignition when I park the car and shut off the engine. I found a procedure in the owners manual for getting the key out. You need to remove the lower half of the steering column and push the interlock release lever. The manual says to take the vehicle immediately to the dealer to have the key interlock system repaired.

    I spent some time studying this and it looks like the lever is supposed to be moved by a solenoid that is actuated when the gear shift lever is moved into park and the release button on the shift lever is released. In my case this solenoid will not move the lever reliably. When that happens the key cannot be turned all the way back into the lock position and thus cannot be removed. In this condition, the steering wheel is not locked so wiggling it from side to side does not help. I tried lubricating the lever mechanism but that didn't help either.

    So I think this solenoid needs to be replaced. Has anyone out there done this before? It seems to be located rather deep on the underside of the steering column and it is surrounded by a lot of structure and parts that look like they would have to be removed. I am wondering how involved this job would be and if this requires removing the steering wheel and dealing with the airbag, etc. I'm just trying to decide whether this job is best left to the dealer.

    Can anyone offer some advice?

  • We own a '09 Outback XT with 9000 miles. On 9/18/09, we suffered a broken connecting rod. Don't know which cylinder yet, but dealer suspects it is #3. Subaru authorized a complete long block replacement, and wants the dealer to let them know which cylyder failed.

    You didn't happen to get water in the intake, did you?

    Just curious.

    On a Pine Barrens run with a water crossing we had a couple of cars take in water. That happened to an Isuzu Trooper. A Subaru XT6 stalled before any damage was done.

    Water doesn't compress like air.
  • "... fuel additives in some fuels result in carbon flakes delaminating from the cylinder walls when the engine cools... "

    I think that car advice page in the Sep 11 Melbourne Herald Sun said cylinder heads, not walls.
  • It was a very sunny and dry day. We had driven about 200 miles, at interstate speeds, when I suddenly heard this loud clatter from the engine. I was doing about 75-80 mph when it happened. The dealer had it towed in, and made the diagnosis.

    Anyone, how often should the filter be replace? What happens if you wait to long?
  • phil2000phil2000 New JerseyPosts: 195
    Let's try this again.

    Anyone, how often should the F U E L filter be replaced? What happens if you wait to long?
  • ateixeiraateixeira Posts: 72,587
    Probably 60k miles, though I think on my Forester I also changed it at 30k.
  • phil2000phil2000 New JerseyPosts: 195
    What happens if you go 100k or more without changing it?

    Fuel filters on the Subarus pre 2005 are done 3yr/36k, after 05 they went to an in-tank filter that isn't user serviceable.

    I have a 2000 Forester. So what problems can or did I encounter by waiting till 100k to replace?
