What are the causes of oil burning in a road roller?
2 Answers
There are many reasons for oil burning in a road roller, such as fuel quality, driving conditions, driving habits, maintenance habits, etc. The above reasons can aggravate oil consumption and lead to oil burning. Poor sealing conditions: Carbon deposits in the combustion chamber cause the piston rings to stick, resulting in poor sealing. Clogged return holes: Sludge in the lubrication system clogs the oil return holes of the oil rings, weakening their oil-scraping performance. Wear phenomena: Wear occurs between the piston and the cylinder wall. Corrosion and aging phenomena: The valve seals corrode and age, causing the sealing performance to fail.
I've encountered road rollers burning engine oil many times, mainly due to aging and wear of mechanical components. For example, when piston rings are damaged or gaps become too large, oil slips into the combustion chamber and gets burned, resulting in thick blue smoke from the exhaust pipe. Failed valve guide seals or cylinder wall scratches are also common factors, especially after prolonged high-load operation. I've noticed that if the turbocharger leaks oil, it can contribute to the problem as well. For prevention, regularly check the oil dipstick to monitor how quickly the oil level drops, and never overfill the oil to avoid excessive pressure forcing it out. Pay attention to engine temperature, as overheating can make rubber parts brittle. Before starting work each time, observe the exhaust color and promptly inspect if any unusual odors are detected, which can save a lot of trouble and expense.
