## Discrepancy

THIS ENGINE HAD 3 CYLINDERS OVERHAULED WITH RINGS IN THE FIELD.  THE FOURTH WAS REPLACED WITH A COMPLETE CHROME CYLINDER ASSY.  AFTER 30 HOURS OF FLIGHT, THE OIL CONSUMPTION AND BLOW-BY BECAME EXCESSIVE.  A COMPRESSION TEST SHOWED 20/80 OR THE 3 OVERHAULED AND 68/80 ON THE CHROME CYLINDER.  THE RINGS IN THE CHROME CYLINDER APPEARED OK WHILE THE OTHERS SHOWED SEVERE WEAR.
