    Why is my car burning mass amounts of oil?
    I have connected my IAC hose to the what i believe is the Valve bleeder hose (hose from drivers side valve cover to intake) on my 98 impreza 2.2. Now my car is burning a ton of oil. Did I break a seal or just draw oil from the valve cover into the engine?

    Air Conditioner runs on and off by itself
    178,000 miles. A/C was recharged last summer. The unit kicks on and off by itself. Noticed in winter, unit would go on, even though switch was off. Also notice couple days ago, with just fan on, water was dripping out of the drain where A/C water flows out (it was ...

      The 2005 Forester also runs the A/C when the controls are in the defrost position. This helps to dehumidify the heated defroster air for better windshield clearing. So, no matter what the temperture, the A/C compressor will engage with this system when defrosting.

      Confirms what my mechanic told me. The unit would cut out in extreme heat situations. Would shut off and after a while, would work again for a little while. Tried applying oil to the clutch, no difference. Ended up finding a short in the compressor. Replace that and filter. Works fine.

      Check the A/C clutch ass\y, take a screw driver approach the clutch flywheel to feel if magnetic force is there try to suck the screw driver closer. If magnetic force is presented then Google it in Subaru forum, there is a nice write up for how to remove the shim in the clutch ass'y. Good luck. May want to check the pressure switch too.

    Minor Trouble Starting; pump gas and it starts up.
    165k, half tank of gas. Car sat idle for a day and a half, went out to start it and the starter turned strong but no turnover. It usually starts up right off the bat, no hesitation. I stopped trying, let it sit for a few seconds and then tried again; pumped the gas ...

    What is a knock sensor?
    Replacing a knock sensor

      An engine knock sensor is actually misnamed - should be called an anti-knock sensor. It is to sense the engine knocking (detonation) in the cylinders due to the ignition flame and fuel incomplete burning.
      The knock sensor responds to spark knock (pinging) and will adjust (usually retard) the timing though the ECM (engine control module) to prevent knocking in the engine and helps reduce damage from knocking.

      Several possibilities; coolant mixture is incorrect (not at recommended 50/50 water and anti-freeze), faulty thermostat, faulty / clogged radiator hoses, faulty water pump, clogged / restricted cooling passages in the engine, fan belt stretched or slipping.

    What causes rough running after fueling?
    Engine runs fine all the time except after filling with gas. After filling it is hard to start and runs rough for about a minute, then smooths out and runs fine till I fuel up the next time.

    Engine is overheating, coolant is overflowing into overflow container and spraying engine (LHS)
    Pressure checked hoses, changed radiator cap, did a fluid flush. Happened again. Is the thermostat gone bad or is it an engine gasket? :-(

    Just had a transmission installed, ac installed, now need a $1500 head casket replacement. Should we fix and then sell
    High milage (not sure of #). Should we fix then sell or take for trade in.....HELP

      I doubt you can re-coupe the 1500 when selling it, but hard to get what it's worth on a trade in. Sounds like you need to get the actual numbers and then compare.
