Engine Overview and Common Failures
The weight of the 2AD-FTV engine according to the catalog is 190 kg. The engine number 2AD-FTV is located at the junction of the block and the gearbox. A known problem of the engine is erosion of the mating surfaces between the block and the cylinder head, as well as frequent blowing of the cylinder head gasket, causing gas or oil leakage into the cooling system or cylinder. Another issue with these diesel engines is high oil consumption, often observed from the first kilometers of mileage. There have even been campaigns to replace pistons under warranty, but the oil consumption did not decrease significantly. It is advisable to replace the washers under the injectors every 60,000 km, but rarely do people actually do it, resulting in the washers deteriorating over time. This can cause injector clogging and breakage during disassembly. Like any modern diesel engine, this engine has a typical set of problems: regeneration failures and failure of the DPF (diesel particulate filter), frequent EGR valve clogging, limited lifespan of piezo injectors, and turbocharger geometry sticking due to carbon deposits.
