Ring engine problem Brisbane - FLOGGED / WORN OUT / OIL USAGE

Piston rings do wear out as they are constantly in friction contact with the cylinder bore. The piston rings are also subject to contaminated oil, air and fuel. With good service history piston rings may commonly last as long as 250,000k. Often piston rings become unserviceable long before they should due the operating conditions and service history. Every time a cylinder fires the resultant combustion forces the piston ring out against the bore, so when you consider the longevity of a piston ring all conditions have to be near perfect to eliminate premature failure. Some conditions that will shorten the expected life of the piston rings are as follows: (1)Insufficient oil and oil filter changes lowering the effectiveness of the lubrication. (2)Poorly honed bore causing blow by and piston ring damage. (3)poor quality or incorrect piston rings used for the particular application. (4)piston rings fitted to worn out pistons with worn piston ring lands. (5)Air born contamination caused by poor air filtration. (Dusted) (6)incorrect oil and run in procedures causing glazing of bores. When an engine is dismantled some telltale signs will be evident to determine the cause of premature piston ring failure. visual evidence like a golden colour covering a nice hone pattern indicates the bore and piston rings are glazed up. "Glazed bores" are usually caused by insufficient load applied to the engine during the running-in period or a very light load during the crucial initial road test, incorrect oil containing anti-frictions not suitable for running- in or in the case of doing a re-ring without honing. Diesel engines are more prone to this condition than petrol engines due to the oily nature of the diesel fuel. Diesel engines should be subject to the least amount of idling and light loads during the initial stages of run-in. To prevent Glazing of bores in reconditioned engines the bore should be plateau honed and the engine being subject to controlled medium to heavy loading during run-in.
