    I have 86,000 on my Forester SUV - Check Engine light was on - and it didn't have the pickup it once had. Dealer replaced the catalitic converter - is this normal after only 86,000 miles - always use Regular Gas in it! Any thoughts on this?

    We don't really have enough info to go by, but that seems pretty early for a Cat failure.

    Though if you have a misfire (which would trigger a check-engine light) and keep driving for a long period of time the unburned fuel that gets through would eventually clog it up.

    My 2006 Forester has 48,000 miles on it. When traveling at 55 miles and hour, there is a thumping sound coming from the engine when I accelerate.

    It is not from the wind, because it is only when I hit the gas pedal.

    My questions is: Does anyone have any ideas of what it might be? When I say thumping, it is like a fan blade or some plastic that flaps in the wind. I know it is not that, I has that checked out? Thanks. :sick:

    Tires?
    Axles?
    CV Joints?

    I'm thinking tires also. See if the wheel well liners are loose and rubbing up against the tires.

    That happened to my Miata after a visit to the body shop - they didn't secure the fender liner properly at first.

    Along those lines the undertray could also be loose from an oil change too.

  • Hello,

    My wife's 2004 Forester has 63,000 miles and today she said the engine started to vibrate, and a little later smelled a burning smell. She checked the car when she got home and didn't notice anything. I started the engine and noticed that the 2 fans behind the radiator were cycling on and off (about every 30 seconds) while idling. I know my 2006 does not do this. I took the car for a drive, and after about 6-7 miles, I experienced the same thing - engine vibration, as well as a little loss of power.

    Does anyone have any thoughts on this?

    Just found out from my local mech. that my 2003 Forester has a leaky head gasket (drivers' side). Because of the head gasket issues prior to 2001, I called Subaru customer service, but because my forester's got 125,000 miles on her, the guy said "tough luck" (just paraphrasing). He said I should first get a dealer to officially diagnose the prob and then Subaru will review the case.

    What are my chances of getting a little help with the (gasp!) cost??

    To be fair that is very high mileage... I mean, even if you had bought the most expensive extended warranty you would not be covered.

    See if they will pay for parts, and you pay for labor.

    Honestly, if they offer any discount at all I think they're being generous.

    125k is more than double the promised 60k powertrain warranty.

    I have a 2004 Forester XT with 105K miles on it, and today I found out that my connecting rod is knocking into the block and that my engine is basically shot. I am devastated. I have had my share of problems with this car, but I love it, and this is disappointing beyond belief. I have been excessively diligent with the maintenance on this vehicle and I have all records to prove it. I bought it in 2006 and it had 58K miles on it then. I have put a lot of miles on this car in the last 2.5 years, but is there any reason why such an important component of the engine would go bad so soon when the car has been well taken care of? What on earth should I do? My mechanic estimates that a rebuilt engine will probably cost me about 3K.

    So, chances are not great that Subaru will take pity on my high mileage Forester with the leaky head gasket. There were references earlier in the forum to stop-leak products used by dealerships, and I'm wondering if they are a viable way to get another 50,000 miles out of my car without fixing the gasket. As a temporary measure now, would an additive allow me to fix the leak later?

    Anyone have real world experiences with stop-leak products?

    This results from very worn or damaged big end bearings. It is likely that the first owner abused the engine for the first half of its life by frequent boost and infrequent oil changes.
  • I used stop leak products decades ago. They coat the whole cooling system with a residue to stop a pin hole leak at one point in it. The coating can reduce the cooling capacity of the radiator.
  • Just thought I'd update on my 2003 Forester with the leaky head gaskets.

    Called Subaru and they kindly agreed to pay HALF the cost of replacing the gaskets, even though the warrantee extension only applied through the '02 models. Apparently the 03's are not entirely free of the problem.

    I was very happy with the agreement, since I was sure I'd be out of luck completely. I had to pay the bill up front and am now waiting for reimbursement.

    Moral: It doesn't hurt to ask.
  • Congrats on that! :)

    Sweet and congrats to Subaru for doing right by the customer. Although they were under no obligation to help out, by doing so they demonstrate their willingness to stand behind their product.

    Hey,
    Just bought a manual 1999 2.0 turbo S. Seems to splutter when accelerating hardish from low revs, replaced air filter, fuel filter, spark plugs and ignition leads to find it still has the same fault. Engine/ turbo pulls like a train once it hits around 3000rpm but anything under that in 2nd or above gears engine is very jittery and almost misfiring although the engine management light does not come on at all...If you lightly accelerate in this rev range it is ok but maybe still a bit jerky when you take your foot off the accelerator pedal????
    Any help would be appreciated as i have fallen for this car and want to enjoy it!!!

    Cheers

    I would first try running some fuel system cleaner through it on a couple of back to back tanks.

    I assume that you bought a Forester since that's the name of the topic. In the U.S. the Forester has always had the 2.5 litre engine and didn't get the turbo until 2004. What country are you in?

    Hey Frank, It is a forester 2.0 turbo S, registered 1999 in England but is now with me in Bonny Scotland, Edinburgh. Have been struggling to find anyone who would have a clue about these apart from some impreza sites in the uk which cost a small fortune to join up.

    Put a new Mass Air Flow sensor on it yesterday, this has made a difference to overall pick up and it does respond better now although the original fault is still there around 2000rpm, is smooth if a small amount of throttle is given but if you plant the loud pedal it stutters away until it reaches the magic 3000rpm turbo range... engine revs like a dream not in gear, rev pickup is rapid and purrs like a kitten on idle but only when under load and on the over run around this rev range it is jerky ????
    Will Put some fuel cleaner in it tomorrow and i will clean out the throttle body, have done some small checks for air leaks but nothing apparant at a glance?

    I know this car can run better and its so frustrating not being able to drive it smoothly.

    Cheers
    Russell
