been hearing and reading nothing but good reviews about these motors Ford is putting in there Rangers and Focus. I'd like to hear what you duratec owners say and how well do they compare to the Lima engines? -Mike-

Great engine so far. (fingers crossed)

After about 3 years, the engine broke in and started getting really great mileage. Still pulls strong, and moves pretty fast for a 4 banger. I have no complaints.

only problem i had with mine was the thermostat when out around 75k miles, and its located on the back side of the engine, and is not something i was able to replace myself

also, compared to my wifes 99 2.5, the duratec is a beast

I ran my old Lima over 170,000 with no problems. Always ran great, never any problems. Underpowered, but tolerable with a stick. Was very easy to work on.

cool! yea my 2.5 isn't so bad to work on once you get to know a few things about it. You just have to get creative sometimes.

I can't say I don't like my 2.5 but I can't say I love it either. I've had my share of issues with it, just nickel and dime stuff except when the tranny went out and saw the bill for the rebuild which was not worth a penny in my book, that's another ballgame.

Thanks for the feedback! -Mike-

I've had both the Duratec and lima 2.3 and both standard 5spd trans. The Duratec gets significantly better mileage (I usually get about 30 on the highway), and has loads more power, especilly at high revs but even off the line. And is quicker to rev, so makes starting on a hill easier.

I've only got 10K miles on it though, so I can't say anything about longevity, though i haven't heard of anyone blowing one yet and they've been building 'em since 01. The mileage got significantly better after it broke in.

The only pluses to the lima is 1) it does a better job of slowing the truck down when going down hill in gear--the duratec in gear feels like driving an automatic downhill. And 2) seems a little smoother running--these duratecs are a little rattly at an idle. Neither one of these is a biggie. I'm plenty happy with more power + better economy!
