AutoMD Member - 2009 Subaru Impreza - Engine - 10/27/2013hi, my car has done 30000 miles and has recently stated using engine oil, about 1 litre in 2000 miles, can any one help please.
10/27/2013 CVOWorn valve stem seals will allow the engine oil to penetrate into the combustion chamber. Normally the oil consumption occurs in the engine with a higher mileage ( 70,000 miles ).See this site for valve stem seals.
Note: use the engine restore oil, it does help to reduce the oil consumption but not a 100% seal it.

9/28/2013 HouseCallAutoDid you monitor fuel mileage and get a miles per gallon number?
9/29/2013 JimmHere are a few engine problems that hurt fuel economy:
- missing or defective thermostat, causing low operating temperature
- clogged intake manifold exhaust crossover passage (for heating intake manifold)
- engine misfire caused by bad spark plug, ignition wire, coil, dist. cap or rotor
- late ignition timing
- bad vacuum advance unit (common in old cars)
- stuck centrifugal advance mechanism in distributor (needs oil occasionally)
- bad tension adjustment of centrifugal advance springs (inside dsitributor)
- defective oxygen sensor (causes rich mixture)
- defective coolant temperature sensor for engine computer (causes rich mixture)
- worn timing belt (may cause rich fuel mixture in fuel injected cars with a MAP sensor)
- incorrect timing belt installation (timing marks should line up)
- dirty mass air flow sensor (causes rich mixture)
- dirty air filter (causes rich mixture at high power)
- clogged or defective PCV valve
- incorrect valve clearance (especially if too tight)
- worn valve guides (makes fuel mixture too lean at low power)
- vacuum leak from bad vacuum hoses or intake system gaskets (causes lean mixture)
- dirty fuel injectors
- bad fuel pressure regulator
- bad MAP sensor for fuel injection
- leaking intake duct between air flow sensor and throttle body
- rusted or missing exhaust heat stove or pipe for heated air intake
- loss of compression pressure due to worn rings or leaking valves
- sticking EGR valve (causes rough idling and rich mixture on some engines)
- increased exhaust back pressure caused by clogged catalytic converter, muffler or crushed pipe
- stuck exhaust manifold valve for some engines. Intended for fast warm up.
Other than these list of engine problems; there are other possibilities -
fuel system leaking, low tire pressure, wheels mis-aligned, brakes dragging / not fully retracted
alleyneben1 - 2006 Subaru Impreza - Engine - 9/20/2013Is this vehicle under recall my daughter has a 2008 and had the same problem which was covered under a Recall Notice ??
9/20/2013 JimmCheck the applicable recalls on the follwoing websites; www.AutoMD.com, www.arfc.org. Looks like there are only two (2) recalls for the 2006 Subaru Impreza - one for the air bags, and one related to the front suspension / front lower control arm.
The timing belt replacement is usually at 60k intervals - though at 46k miles it would not hurt to replace. Be sure to go ahead and replace the water pump at the same time - the water pump is usually included in the timing components kit. Check the many on-line auto parts sources, such as; www.autopartswarehouse.com, wwwpartsgeek.com, www.autoanything.com and www.rockauto.com - to list only a few sources. For example, they (Rock Auto) list the timing component kit from around $181.00 for your vehicle. Gates part # TCKWP304A Premium OE Timing Belt Component Kit W/Water Pump; 6 Components (1 Belt, 1 Hydraulic Tensioner, 3 Idlers, 1 Water Pump)
Keep in mind that the 2.5L flat six cylinder is an interference engine application - meaning that if the timing belt should break in operation, the pistons will contact the valves and major engine damage will occur.

mtnspool - 1999 Subaru Forester - Engine - 9/9/2013My car has not been running in a few months and the emergency lights keep flashing. Where is the switch so I can remove it. It is on after engine is off.
9/9/2013 bear.1216The flashing lights may be the security system. When a car sits for a long time the battery will get weak and the security system can turn on making the lights flash and may disable vehicle. You may need to reset the alarm. The hazard switch is on the dash or steering column. Removing the switch may not disable lights if security issue It has the symbol of a triangle with a lightning bolt inside. If you want to disable the hazards it would be easier to pull the hazard relay or fuse. This will disable hazard lights. Sorry but I cant tell how to disable or reset security system. I dont teach people how to steal cars.
