Engine Overview and Common Failures

The weight of the 4A91 engine according to the catalog is 130 kg. The engine number 4A91 is located at the joint with the gearbox. This reliable unit is known for its oil consumption already at a mileage of 100,000 km. The cause of carbon deposits is the piston ring sticking or worn oil scraper rings. Sooner or later, this leads to oil starvation and bearing rotation. Leaks from the front crankshaft seal are also frequently encountered on high mileage. The sealing ring between the manifold and the catalytic converter often burns out as well.
