Engine Ford Duratec HE 2.0 with 145 hp by its construction is the same as 1.8 liter, but with cylinders with larger diameter (83 mm to 87.5 mm). Was developed by Japanese company Mazda MZR series model LF, used Ford in the framework of cooperation between the two companies. Comparing it with the 1.8 liter, the 2.0 on all sides of it seems less preferable. The 1.8 is more elastic, more powerful, quieter running, without flaws floating speed. Resource of Duratec engine Ford / Mazda LSB 2.0 according to the plant is 217 480 miles, but real lifespan is 310 500 miles without a major overhaul.

There are also timing chain drive, which significantly improves the reliability. All engines have a problem fragility camshaft seals. Often, the thermostat breaks before 60 thous. miles, and the engine is not heated or overheats. You also need to monitor the state of the spark wells, in case of oil it is necessary to tighten the valve cover or replace gasket. If, after 3000 rev / min machine refuses to go and there is a Check Engine prob;em, then it’s time to replace the intake manifold flaps control valve. In addition, every 100-150 miles you need to adjust the valve clearances, because of the lack of the lash on Duratec HE 2.0. By the way, there is no lash on engines of Ford Focus 1.4, 1.6, 1.8, 2.0 at all. In spite of all these little things, 2 liters – is a very good motor, reliable and is considered as one of the best engines among Ford Duratec. In 2010 the motor was replaced by his own restyling version Duratec HE GDI Ti-VCT, with variable valve timing, 150 hp.

  1. Question about 2013 Ford Transit connect with the 2.0 L duratec engine.
    I bought this van last march, it had 32,000 miles.
    The previous owner stated that he got tired of the vibrations of the engine.
    It run well, just has a vibration from the engine,, the motor mounts are fine and all.
    This engine just seems like a cheap economy engine. Is this engine known for vibrations??
    It’s really annoying when idling. makes the whole van resonate.
    I have to readjust my rearview mirror at least once a week.
    Being this engine is in a van, it has a hard time to keep up 70mph on the interstate. forget about using cruise control. it’ll keep struggling to keep up the speed, and keeps downshifting.
    The van is kinda tall and has a ladder rack on top, so i know the van fights the wind.
    I think if it had about 25 more HP, it’d be fine..

    Anything that can be done to give it some more umph ?

      Hi there! It’s a common problem which can have many reasons.

      You need to check if there are any errors using scanner or through the dashboard (there are definitely errors there, but you need to understand what exactly is broken).
      Probably you would have to change spark plugs. It may just be one missing cylinder causing all this.

    I have a 2008 Mazda CX9 Grand Touring. My vehicle has 140,000 miles . My Mazda went out on me about 15 months ago. The problem is with the Duratec Engine. When this engine was built the water pump was put in the engine. When the water pump gave out the water and oil mixed together,and now I have no car to drive. I meant to mention it has a V6 engine. Do you know of anyone that can fix my car,so I can be able to drive it again. I love this car it’s Black Cherry,with black leather seats. Thank you Mrs.Denise Wilson
