WHAT'S THE PROBABLE CAUSE OF ENGINE USING OIL (NO EXTERNAL LEAKS). APPROX. ONE QUART EVERY 500 MILES

1999 Subaru Forester • 145,000 miles

Vehicle purchased new and properly maintained; started using oil approx. Three years ago; other techs indicate this year engine has known problems with so called "blow by".

Have the engine compression check to determine if its rings/valves/cylinder wear
