LEAKY LINERS AND CYLINDER COVER ARE NOT SOMETHING THAT HAPPENS OFTEN. IT IS RARE BUT WHEN OCCUR CAN HAVE SERIOUS TROUBLE FOR ENGINE AND HAVE TO BE TACKLED QUICKLY. WHILE THE ENGINE IS RUNNING THE PRESENCE OF BLACK COLOR WATER IN EXPANSION TANK IS AN INDICATION THAT LINER IS LEAKING.
TO FIND OUT WHICH LINER IS LEAKING WE CAN STOP THE ENGINE AND HAVE TO DO UNDER PISTON INSPECTION . THE PRESENCE OF WATER IN THE UNDER PISTON OF THE PARTICULAR LINER SUGGEST THAT IT IS LEAKING. IN CASE OF CYLINDER COVER IF LEAKY FROM INSIDE THE OBSERVATION WILL BE THE SAME.
NOW THE CORRECTIVE ACTION THAT CAN BE TAKEN IN CASE WE HAVE TO SAIL WITHOUT OVERHAULING THE UNIT TILL WE REACH A PORT, COMPRESSION AND COMBUSTION BOTH HAVE TO BE STOPPED. THIS IS BECAUSE LINER OR CYLINDER COVER IS ALREADY DAMAGE AND HENCE COMPRESSION AND COMBUSTION WILL CAUSE MORE DAMAGE AS LINER OR COVER ARE ALREADY WEAK.
HENCE FIRST OF ALL THE FUEL PUMP ROLLER IS LIFTED UP AND FUEL IS CUT OFF FROM THAT UNIT.
NOW THE EXHAUST VALVE IS MADE TO REMAIN OPEN BY STOPPING THE AIR SPRING AIR AND TO LIFT THE EXHAUST VALVE ACTUATOR ROLLER UP. OIL INLET FOR ACTUATOR IS BLOCKED OR PIPE IS TAKEN OUT.
STARTING AIR LINE IS BLANKED.
THE MOVING PARTS LIKE PISTON AND CONNECTING ROD ARE STILL OPERTIONAL AND CYLINDER LUBRICATION AND CROSS HEAD AND PISTON LUBRICATION ARE STILL ACTIVE AND UNTOUCHED.
