## Discrepancy

OIL SCAVENGE LINE FROM LEFT TURBOCHARGER INTERNALLY COLLAPSED CAUSING LEFT TURBO TO PUMP OIL INTO INTAKE AND OUT TAILPIPE, 3 QUARTS OF OIL LOST IN APPROXIMATELY 1.5 HOURS.  REPLACED ALL OIL SCAVENGE HOSES WITH NEW, SINCE ALL HOSES DATED SAME, 12/21/90 AND ALL HAVE ONLY 660 HOURS.  SUBMITTER RECOMMENDS THESE HOSES BE REPLACED WITH TEFLON INNER WALL HOSES OR RIGID LINES, OR BE REPLACED AT EARLIER INTERVALS THAN 5 YEARS 2,000 HOURS AS RECOMMENDED.
