## Discrepancy

NR 6 EXHAUST PUSHROD BENT, BROKEN AND WORN HALFWAY THRU FROM RUBBING ON INSIDE OF THE PUSHROD HOUSING.  NR 6 INTAKE PUSHROD BROKEN IN TWO.  CYL HAS 190 HRS SINCE NEW AND BOTH VALVES MOVED FREELY IN GUIDES.  NR 6 CONNECTING ROD FOUND VISIBLY BENT.  INTAKE MANIFOLD DRAINS DID NOT DRAIN WHEN TESTED.  POSSIBLE CAUSE, HYD LOCK, TCM SB96-11.  NR 6 CYL ON THIS INSTALL (RT ENG OF BEECH BARON) IS FRONT INBD CYL.  CANT OF ENG WOULD MAKE THIS A LOW SPOT IN INTAKE WHERE FUEL WOULD ACCUMULATE.  WITH FUEL DRAIN INOP, IT WOULD NOT DRAIN OUT.  RECOMMENDATION IS TO INCLUDE  A TEST OF MANIFOLD  DRAINS AT 100-HR ANNUAL INSPECTION.  (X)
