Disadvantages, breakdowns and problems of the 4D68 engine
- Frequent oil leaks. The engine is prone to oil leaks, which reduces its overall reliability.
- Low turbine life. In turbocharged modification (4D68T), the turbine may require replacement as early as 100,000 km.
- Balancer shaft belt. The weak point of the engine is the balance shaft belt, which can break at 50,000 km and cause serious damage.
- Crankshaft pulley. The pulley often cracks, especially at high mileage.
- Exhaust Gas Recirculation (EGR) System. The EGR valve becomes dirty and fouled quickly, requiring regular cleaning.
- Cracking of the block head. At high mileage, the cylinder head may crack, requiring replacement or major repair.
