2002 impreza sport head gasket

Discussion in 'Subaru Impreza' started by runcyclexcski, May 13, 2010.

  1. After looking at older posts I understand that this is a known issue
    on 2.5L engines. My Impreza OB Sport has 150,000 on it; it has started
    eating coolant (actually, with the "genuine" subaru brand the coolant
    was not going as fast, this was generic coolant I added at a gas
    station) and producing white smoke from the exhaust. Runs fine
    otherwise. Just spoke to my mechanic on the phone. Yes, I have a
    failed HG.
    How much did your pay for your head gasket job, and what other repairs
    would you recommend to combine it with? My clutch and timing belt are
    also due. If the bill is below $1,500 I will eat it. More than $2,000
    - don't know. With 150,000, can I expect another 2-3 years? Don't
    wanna buy a new car yet. If I do get a new car, is there anything I
    can do to make this happen not as early (or is it early?)? Subaru
    recommends a special coolant additive - what's up with that?

    well, I think a head gasket cost between 1500-2000 at our shop. now
    with that the timing belt and seals are included.
    clutch is extra. at these miles count on the timing belt idler pulleys
    to be bad. Some secondary shops will do the job for about 500.

    I was quoted $1,300 for the head gasket itself, but with the
    resurfacing of the cylinder heads (is that necessary?) the price came
    up to $2,000.

    Also, the gasket looks intact, the leak seems to be mostly
    "external" (traces of coolant on engine block dripping down), and the
    pressure check did not find major leaks. I have decided to flush the
    coolant and to replace it with Subaru's one, and see what happens.
    Will replace the clutch only. If I can get 2 more years from this car
    by adding coolant every couple of weeks, I am fine with that. Now, the
    white smoke does come out of the tail pipe every now and then.

  4. Shoot. I'll give you the $1500 for the car, get the gaskets, clutch and
    timing belt done and drive it for another 150,000.

  5. Careful what you wish for. :) Actually, turns out I did the timing
    belt at 120,000.

    I am getting the recommended additive and coolant from subaru and
    getting the clutch replaced, fingers crossed.

    Some people say this stuff works. I don't have any experience with it but
    am considering it. Maybe others know?

  7. I wonder, if there is an *internal* leak, and all those glass
    particles penetrate into the engine block - whether that would be
    equivalent to the method they used to kill old car in the cash for
    clunkers program.

    Wow, that's a possibility. Might be why they are so adamant about not
    having it come in contact with coolant. It sounds risky.

  9. BEFORE YOU DO THAT, if you look through this group, you'll see where I had
    leaky head gaskets on an '89 GL Coupe. I used some Bar's HG in a bottle
    stuff, FOLLOWED THE DIRECTIONS TO THE LETTER, and bye bye leaky gaskets!

    It seems the gasket has to have a slight leak or a leak on the intake
    side. I tried again on a '97 Legacy wagon with a BHG on the exhaust side
    to no avail.

  10. Yup! That's it! Worked on my '89 like a champ!

    FOLLOW THE DIRECTIONS!!! You cannot have a single DROP of coolant in the
    system. It took me about 3 hours to flush it all out.

  11. It worked for me. I had a leaky gasket on an '89 Coupe and it is still not
    leaking 2 years later.

    I also made up a bypass hose to get around the heater core. Since this is
    a winter car the last thing I wanted was a plugged heater core! ;)

  12. It clogs passages if it mixes with coolant. Before I even touched the
    stuff I called Bar's and the girl on the phone told me to flush the
    cooling system until clear water came out.
