Engine Overview and Common Failures
The weight of the G9T engine according to the catalog is 227 kg. The G9T engine number is located at the junction of the block and the oil pan. The wear of the timing gear combination drive has an unreliable clearance adjustment mechanism between the gears, where the springs often break. As a result, the gears wear out and their fragments fall into the oil pan. This can also lead to valve bending. The turbocharger pushes oil. At 100,000 km, the turbocharger shaft or its seals may wear out, causing the turbocharger to push lubricant into the intake. And this can not only result in a drop in oil level, but also in its entry into the combustion chamber, which can lead to engine failure. Bearing rotation. In addition to the turbocharger, the oil pump often serves as the culprit for the lubrication system's oil level drop. Not only does the shaft and gears wear out in it, but the reduction valve also gets stuck. Moreover, the oil pressure lamp usually lights up when the bearings have already turned. Electrical malfunctions. The most common service requests are related to electrical failures, and the usual cause is wire breakage. The generator also frequently fails here. Oil leaks. This diesel engine is notorious for regular oil leaks, and there are several weak spots. Most often, the lubricant seeps from under the valve cover or through the timing drive gears.
