    It's about damn time. They better not leave the craptastic 4-speed auto in there either.

    Do you still have to move the engine to change spark plugs? :p

    You got shafted if you have to move the engine in your Forester :D I know the Impreza's have to remove crazy shit like the wiper fluid reservoir, but "all" I have to do is pull the battery and the air intake ;)

    oh really? Good to know! I don't have to change them for another 16k. :p A friend of mine has a Legacy 2.5GT (same motor) and said he has to rotate the engine to get to the plugs.

    Subaru fails!

    Why are they still using an archaic 4spd auto trans in a $25K vehicle?

    Honestly, your friend is an idiot. I had never done it before so I admit to spending 2 hours changing them on my LGT. The only extra thing I removed was part of the intake.

    I don't even know why this whole chain thing is such a big deal to everyone. Its not like they never need attention and they can certainly fail. This really only affects people who are too cheap to properly maintain their vehicles.

    He's usually pretty good with mechanical stuff - far better than me. Interesting - good to hear it's not a big deal.

    I don't see what the big deal is about timing belt / chain either...replacement interval for the belt is 105,000 miles. That's a long time...

    Chains last longer and no maintenance schedule whatsoever, unlike the belt, but you guys know that ;)

    Exactly... My wife wanted to look at one, but I told her I wasn't going to buy a 2010 model with a 4 speed auto.

    Plugs are still a PITA, and if you want to disconnect the motor mounts (which IIRC is a PITA) and probably exhaust too, then you can jack the motor up a bit to get easier access to the plugs. But you would still need to remove the battery and probably the intake, at least on the LGT.

    But in no way do you HAVE to move the engine. The driver's rear plug is the 45 minute job the first time you do it; the rest are 10-15 minutes each. Once you've done it the first time, it's cake.

    And the big deal about the timing chain is that it's likelihood of failure is far less than a belt. This matters because all of the DOHC (and 97+ SOHC) Subaru EJ motors are an interference design - the valves and pistons will collide if the timing is off, i.e. timing belt failure.

    105K miles may not be much, but the timing belt job is a huge PITA to do. It costs several hundred dollars in labor alone.

    As far as autos go, it's not a bad one. The engine is very torquey down low, compared to most four bangers, and the gears are relatively short, so its not terrible. But it really is just...archaic.

    $440 parts and labor at a dealer, plus another $185 for the tensioner. I think I will be doing it..

    Chain > Belt. Timing chains with metal sprockets will easily last 200K or more miles. a Belt you're supposed to change at 90K.

    Unless it's a Lambo, then it will stretch at 90K and trash the motor :eek: :D

    Nobody's arguing that. Belt service interval will depend on the vehicle - 105K for my Subaru and 60K for my MR2.

    Assuming 10,000 miles per year, I don't think a timing belt service every ten years is going to break the bank. Hell I am the second owner of my '04 Subaru at 103k - which means the first owner had it for seven years and never had to change the timing belt.

    With those crummy gas mileage numbers, why would you not buy a real truck? The idea of an econobox-based softroader getting 21/27 makes me nauseous

    Well that's good for you. My 1987 Trans Am only has 140K on the clock so around 6K per year, but my 06 Silverado has 100K on it.
    I prefer vehicles that aren't designed as a means of selling dealership services.

    My truck gets 14/16, and my FXT is a hell of a lot more fun to drive.

    To each his own. I'm happy with go-anywhere in the winter and a 13 second quarter, but that's me. ;)

    I was going to say, my dad's 4x2 Tacoma regular cab 4-banger with stick is only rated 21/27 or so. He certainly doesn't get 21 around town.

    Yeah, I don't know of many (any, really) "real trucks" (I assume he means full size?) that get 27mpg on the highway. Even my Tacoma (V6 4x4 5sp) got maybe 20-21 highway..I don't think you're going to find a full sized truck pulling 27mpg anywhere.

    When Jeep starts selling Wranglers with the diesel, we'll have a real SUV that gets equivalent gas mileage to the Subaru.

    Maxima is from what 2002 or 2003? We are talking about a 2011 car that sells for $25K.
