Subaru Forester Engine problems

    I am not sure which specific seals, but there were two different ones. A small amount of blue exhaust smoke at high revs might not mean anything, but at the rate you are burning oil, I would expect blue smoke constantly. The smell I referred to was almost like burning rubber. There was a problem with grease burning on the exhaust pipes of early Foresters and this smwll was similar, but turned out to be leaking oil hitting the hot pipes.

    Some other possibilities: Are you using synthetic oil? In an older vehicle, I had been using Mobil 1 (original formula) for some years with no problems, but on a high speed trip during hot weather, it all slipped past the rings. During a 1000 mile trip, I ended up replacing it all one quart at a time with regular 10W-30 oil and that stopped the problem.

    Is there another Subaru shop nearby that you can take it to?

    Thanks for all of your suggestions. The problem ended up being bad Valve Guide Seals in Cyclinder#4. They replaced them, and we'll see what happens next.

    We have a 2002 Forester, and had the same trouble. You would start to accellerate, and it would suddenly slow right down. It was a pin hole in a vaccum line.

    I have an '06 Forester X with about 2300 miles on it, and when I start it up in the morning, the engine seems to be running very fast (sounds like a mini diesel), the RPM is between 1 and 2 I think. When the car is put into gear (reverse to back out of the driveway), the engine calms down to normal, and everything is fine after that and it runs smooth.

    Is this common, or is this some kind of problem that needs checked out? I didn't notice it doing this when I first got it 3 months ago -- it had about 120 miles on it then.

    do you have A/C turned on?
  • I have an '04 Auto XT and it does the same thing (runs faster when I first start it before I put it in gear). I do believe this is normal, however. I think it's the car's way of warming up the engine. As you let the engine warm up, the RPM decreases. Alternatively, if you put the car in gear, the car no longer tries to maintain that warm up speed.

    it should run faster... however if it sounds like a diesel, that may mean you are getting some piston slap along with it. If it is a consistent sound every morning, I would get the dealer involved.

    I would just use the new SM regular oils, 5W30. They are probably about 50% synthetic anyway. ;)
  • My 2003 Forester with 60K km and auto transmission. During these 2 mornings, when I started the car, the CEL was blinking for about one to two minutes. The engine was shaking. Ater driving for about one to two km., the light was gone and the engine no more shaking. The temperature was not very cold. It's around 6 to 10 degrees C. I'll take it to dealer to check the coming Monday. Anyone knows what are reasons for the light? My regular warranty expires last year (after 3 years). Will this be covered by the major component warranty, which covers up to 5 years and 100K km.?

    Sounds to me like the oil was too thick. What grade are you using? How long did you let it sit at idle "warming up" :confuse:
  • I use 5w30 and it was changed with oil filter and air filter at the end of last month. I normally do not warm up, i.e. I just start and go. But this morning, when I found the CEL was blinking, I gave a little gas and hoped it would be gone. But it didn't. After about a minute, I drove away. Then after about one km., it's gone.

    So, that tells us if you use the precaution, as you should do with any vehicle, of warming it up for 3-5 minutes, in very cold weather, before driving, the lubricants would be free-flowing. ;)

    You might want to switch, in Winter, to 0-30...

    A blinking CEL indicates an engine misfire condition and should not have anything to do with the weight of the oil.

  • terry92270terry92270 Posts: 1,247

    So far as I know, it is a multi-function indicator, and engine mis-fire isn't the only reason it would be on. Check the Owners Manual....
  • I think Brian is right. According to p. 3-11 of the manual: "If the light blinking while driving, an engine misfire condition has been detected which may damage the emission control system. To prevent serous damage..... The CHECK ENGINE warning light may stop blinking and come on steadily after several driving trips. You should have your vehicle checked by an authorized SUBARU dealer immediately."

    This is the whole part regarding blinking light. The other part is related to CEL staying on steadily.

    If it's engine misfire, can anyone confirm if this is under major component warranty?

    This morning when I started the car, the CEL did not blink nor come on. Please note that the temperature I used was Celsius and not Fahrenheit. This morning it's 2C, i.e. about 35.6F, which was colder than last two mornings, which were around 6-10C, i.e. 43-50F. So I don't think cold weather is the reason. I'll update the situation after I go to the dealer tomorrow morning.
  • The dealer said the CEL was due to ignition coil. It charged me C$408 + taxes for the replacement. Is this price reasonable? Is it normal to need replacement for just 4 years and 60K km?
  • terry92270terry92270 Posts: 1,247
    As I posted, and as Lithia Subaru just told me, it is a multi-function light, not one that merely indicates engine misfire.
  • According to the scan result, the fault code was P0301 Cyl #1 misfire. The reason for the misfire was the defective ignition coil.
  • ateixeiraateixeira Posts: 72,587
    We need the codes to know for sure, but ignition coil is likely, or ignition wires, or spark plugs. All those things can create a misfire condition (blinking means the condition occurs repeatedly).

    A new ignition coil costs about $80 and there's only one, so it's not that expensive.

    $400 sounds high to me. I've replaced one in less than an hour, it's not hard. It's right at the top of your engine, where the spark plug wires end.

    See if they changed the wires or anything else.
