    Why is there smoke or steam coming from the back of the engine (close to the dash)?
    Whenever I go uphill for a prolonged period (1-2 miles), steam starts coming out from under the hood. It smells like burned rubber, and it seems to be coming from the center back area close to the dashboard.

      Most likely, the issue is a leaking heater core, or leaking heater hoses. Check on-line for the many parts supply sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.

      Make sure to check and refill the coolant level - as first step - with the engine / cooling system cold. Then, have the CEL diagnosed for free.

    I have a knocking coming from the front end when making a left turn and giving it gas
    as soon as the wheel is straightened out, it seems to stop. I had a timing belt, air cleaner and oil filter replaced and the boots are ok. This has been going on for a least a year and is getting much worse. Just had 4 new tires put on.

      This sound would be related to the CV (constant velocity) joint of the axle shaft being worn out / excessive play. Time to replace the axle shaft with a new or rebuilt unit. With time and mileage - the sound will only get worse until correctly repaired.

      Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts. For example, they (Rock Auto) list the drive axle / halfshaft assembly (including the CV joint) for around $41.00 (right or left sides) for your vehicle.

    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.

    What is a knock sensor?
    Replacing a knock sensor
     
    • Jimm

      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.
