Engine Overview and Common Failures

The weight of the 4D56 engine according to the catalog is 193 kg. The engine number 4D56 is located at the junction of the block with the gearbox. Cracks in the cylinder head. This diesel engine is afraid of overheating, and the cylinder head gasket regularly blows out. But replacing the gasket won't be enough, you'll have to grind the mating surfaces. After a couple of misfires, cracks near the valves or pre-chambers can often be found. Crankshaft failure. Another serious problem of this engine is crankshaft failure, and it often happens during prolonged operation at low engine speeds. Engines with the Common Rail system have thicker crankshaft journals and breakage occurs less frequently. Fuel system. For obvious reasons, the fuel system is the main concern for owners of such engines, and this applies to both swirl chamber and Common Rail versions. There is no point in listing all the problems, it is a topic for a separate and very large article. Timing belt breakage. The timing belt does not have a long service life and does not always last the recommended 90,000 km, especially if it is not tightened every 30,000 km. In case of breakage, it only breaks the rocker arm, but in the Common Rail version of the engine, it often pulls out the fastening bolts of the camshaft brackets. The balance belt usually gets caught under the timing belt and also breaks. Other drawbacks. Oil leaks are also common here, practically all gaskets and seals sweat, the crankshaft pulley and vacuum pump have a low service life, the EGR valve gets clogged, there are many troubles associated with air entrainment, and even with the slightest tuning, pistons can crack. And don't forget to check the valve clearance every 20,000 km, otherwise they will simply burn out.
