Engine lubrication system plays a vital role in the normal operation of the engine, low engine oil pressure is only the ultimate failure of the system in the form of expression, the result may lead to damage to the piston, crankshaft and its size of the tile and other engine parts, in order to prevent the occurrence of such failures, is now caused by low engine oil pressure causes and its solutions are summarized:
1. Engine oil storage is too small, resulting in the lubrication system without oil or less oil, resulting in low oil pressure. Solution: replenish the oil.
2. Dirty or viscous oil causes the oil pump can not effectively inhale and pump out the oil, resulting in low or no oil pressure. Solution: Change the oil.
3. Thin oil or high engine temperature caused by oil thinning, will leak from the engine friction gap, resulting in low oil pressure. Solution: change the oil or overhaul the cooling system.
4. Oil leakage from the oil pipe, oil pump damage or wear and tear of its components will lead to reduced oil intake, pumping out the amount of reduced, or no amount at all, resulting in low or no oil pressure. Solution: overhaul.
5. The clearance between the crankshaft and the large and small tiles exceeds the standard, leading to oil leakage, resulting in low oil pressure. Solution: overhaul.
6. The spring of the pressure limiting valve or pressure relief valve is too soft, hairpin or ball damage causes the function of the valve to disappear or weaken, resulting in lower oil pressure. Solution: Replace and overhaul.
7. Low oil pressure due to malfunction of oil sensing plug, pressure gauge or circuit. Solution: Replace and check.
