Legger inn en lenke og et utdrag om dette emnet: 1.0 EcoBoost Engine Problems and Reliability First of all, the engine has only direct fuel injection and no fuel in the intake ports. The fuel in the ports acts as a natural cleaner. Without it, soot and carbon layer covers the intake valve stems and restricts the airflow through the ports. Dirty intake valves have problems with a tight closing, which leads to loose of engine power and serious damage of valves and valve seats. As a rule, it will inevitably be detected in engines with big mileage. The engines produced before 2014 had a problem with a bottom hose of the coolant system that would split and dump the coolant off, while the temperature sensor shows a normal temperature. A lot of engines were browned up until Ford changed that hose by redesigned one. That coolant issue is the biggest one. There is a pipe that runs from the expansion bottle to the engine that can also crack and lose its coolant. So keep an eye on coolant level. High-mileage engines can suffer from issues with fuel pressure. The low fuel pressure produced by fuel pump doesn't allow the engine to achieve its full performance numbers. Replacing the worn cam bucket with a new one can increase fuel pressure and performance. The 1.0 EcoBoost engine got a bad reputation at the start of its life. But many issues were fixed and reliability was improved. Blown head gaskets and coolant leakages happen rarely. Many car owners report mileage of 80-100k miles without any engine problems. Together with its strong sides such as extremely low fuel consumption, high torque, and low emissions tax, the engine is a good choice in modern reality for a compact city hatchback or even bigger car.
