Chapter 8 PERIODIC INSPECTION AND MAINTENANCE PROCEDURES
Fuel and Water Ingress In Engine Oil - Inspect
Sample 1 to 2 Liters [0.26 to 0.53 U.S. gal.] of engine oil, and check for abnormal odor and discoloration to deter-
mine the mixing of fuel and water.
If fuel is mixed with the engine oil, the oil will smell like fuel.
If water is mixed with the engine oil, oil may turn milky white in color.
If fuel or water mixture is found in the engine oil, find the cause and repair. If you cannot repair, contact your local
dealer.
If the coolant enters the engine oil during operation, moisture vapor is discharged from the breather. In such case,
locate the fuel or water leak, and repair properly.
Note: If oil leaks from oil cooler, oil will float in water in the freshwater tank. Also, LLC that is not miscible with oil will
accumulate at the bottom of oil pan.
Oil Pipe - Inspect
Oil Pipe and Clip - Inspect and Replace
Visual Inspection at Overhaul
Loosen clamp fixing bolt and check clips and pipes for
wear. If defective, replace the pipe assembly with a
new one.
During Every Other Major Overhaul
Replace the pipe assembly with a new one.

If the engine operation is continued with fuel or water mixed in the engine oil, the engine oil viscosity will decrease
and this can cause serious accidents such as bearing seizure.
