Consumer Description

AT 15,500 MILES, MY 2008 SUBARU STI EXPERIENCED A RINGLAND FAILURE ON THE #4 PISTON. THIS WAS VERIFIED VIA A COMPRESSION/LEAKDOWN TEST. A LONGBLOCK REPLACEMENT WAS APPROVED BY SUBARU OF AMERICA. MY MAIN CONCERN, WITHOUT TAKING ENGINE COMPONENTS OFF, THIS MILD CRACKED RINGLAND WAS ALMOST UN-DETECTABLE. THERE WAS VERY LITTLE DEGRADATION IN PERFORMANCE, FOR RUNNING ON 3.5 OF 4 CYLINDERS. IN ADDITION, MY MECHANIC ALSO FOUND FUEL IN THE OIL PAN. *TR
