High oil level
Drain excess oil and maintain the recommended oil
level.
Oil is milky Replace oil and maintain the recommended level.
Scavenge return line tube clogged
Remove and clean the clogged scavenge return line
tube.
Replace the internal pipe.
High discharge oil temperature (DOT) Refer to the diagnosis procedure for high DOT.
Improper grade of oil Use ELGi recommended air lube oil.
Separator punctured/collapsed Replace with a new separator.
