There are no hydraulic tappets or lifters on the engine. The Duratec HE 2.0's engine life is projected to be about 220,000 miles, although vehicles equipped with the engine may have a mileage of over 350,000 miles.
The new Duratec HE GDI Ti-VCT engine replaced this engine in 2010. The Duratec 2.0 engine, on the other hand, will be known as the most reliable and durable of all Duratec engines.
