Engine lubricating system and cooling system are independent of the
two systems, under normal conditions, engine cooling water will not
enter the oil pan. In the practical work, however, often encounter the
phenomenon of cooling water into the OIL PAN GASKET.
Oil sump water, oil dilution, deterioration or even emulsification. Not
resolved in a timely manner can cause mechanical wear, and even lead to
axle burned down.
1. engine oil sump water failed primary image
(1) not cooling properly reduced.
(2) the oil pressure decreases. If the oil pressure is reduced at the same speed 100~200kPa should be checked for time reasons.
(3) continuous firing or let stand a few hours later, major increases in oil level in the oil pan, engine oil quantity, not less, increasing, sometimes overflows from the Vernier scale.
(4) the crankcase and breathing apparatus with white mist phenomena, sometimes also of breathing apparatus drops.
(5) the oil pan into the water early in the oil drops, for a long time, the oil will become milky white.
(6) water “boiling” or “double bubble” phenomena. Description cylinder liner cracked, water enters the sump.
2. Reasons for engine inlet
(1) cylinder liner seal ring seal is bad.
(2) the oil cooler is damaged, some cooling water into the lubrication system.
(3) some engine cooling water pump bearing is oil lubrication of the engine, if the water seal, and seal the aging or damaged, water will enter the lubrication system.
(4) cylinder liners has cracks or cylinder “pitting” caused serious holes, water will seep into the cylinders into the oil pan.
(5) cracked the cylinder cover, cooling water directly into the cylinder into the oil pan.
(6) hole at the top of the cylinder cover bulkhead loose due to vibration so that cooling water by putting holes into the oil pan.
(7) the tappet Interior body as Foundry Sand hole, inner cooling water leak out of trachoma, tappet room back into the oil pan, this fault is difficult to check.
(8) the engine cylinder head gasket connecting after being washed with water, cooling water directly into the cylinder flows into the oil pan.
(9) the water seal between the cylinder head and cylinder damage. If the cylinder head bolts is loose, also causes the cooling water into the cylinder.
(10) for dry-type sleeves, if the body was “CAVITATION” grave, water body into cylinder liner, cylinder bore damage due to uneven heating, cooling water still have cylinder liners into the oil pan.
