## Discrepancy

WHEN TRYING TO REMOVE CYLINDERS FOR A TOP OVERHAUL, FOUND TORQUES VERY HIGH TO ALMOST FINGER TIGHT ON CYLINDER STUDS AND THROUGH-BOLTS.  THIS ENGINE HAS TORQUE PASTE STILL IN PLACE - ONE-HALF INCH DRIVE AIR WRENCH DID NOTHING - HAD TO CHISEL TWO NUTS OFF SO FAR - TWO CYLINDERS TO GO.  SUBMITTER SUGGESTS QUALITY CONTROL SEVERELY LACKING ON THIS FACTORY REMANUFACTURED ENGINE.  ENGINE WAS INSTALLED JUNE '89.  NO PRIOR PROBLEMS.  BROKE CYLINDER WRENCH ON NR 2 CYLINDER.
