IN ADDITION, MY MECHANIC ALSO FOUND FUEL IN THE OIL PAN. *TR

IN JANUARY OF 2009, I BEGAN TO SEE WHITE SMOKE COMING OUT OF MY EXHAUST ON STARTUP. I HAD JUST OVER 1,200 MILES AT THE TIME. MY ENGINE FAILED SUFFERED A FAILURE AT JUST UNDER 2,000 MILES. SUBARU REPLACED THE ENGINE UNDER WARRANTY AND SENT ME ON MY WAY. FAST FORWARD TO JUNE OF 2009 AND NOW I'M BEING TOLD MY ENGINE HAS AGAIN FAILED DUE TO THE PISTON RINGLANDS CRACKING AND BREAKING OFF. THIS IS A WIDELY REPORTED ISSUE FROM 2008 STI OWNERS AND WOULD SEEM TO INDICATE A POSSIBLE DEFECT IN THE PISTON DESIGN. *TR
