2006 Escape Hybrid: Catastrophic Engine failure @ 65,000 miles

Re: 2006 Escape Hybrid: Catastrophic Engine failure @ 65,000 miles
With regard to disposing of the engine without tear down... no sweat, I got the concept. Just my old Navy engineering sense talking.
About that overheating of the bearing: this can happen quite fast if all oil was cutoff which can happen with dirt in the oil flow path. You wouldn't see the overheat in the water temps, its a very local thing right at the bearing & the cooling water jacket is distant from the crankshaft bearings. They're cooled by the oil (which apparently was cutoff).
But it would be worth taking apart the oil filter, just to have a look see. In my opinion the cause was jiffy lube. Engine design & technology has been hammered out for over a century. These engines just don't fail like that. There was a cause and its very, very likely related to the most recent change in something: e.g. the jiffy lube experience.
I do my own oil for a reason. Its not that the average jiffy lube guy isn't trying to do a god job. Its that I don't want to be the guy that has your experience for the one in a thousand bad jiffy lube guys. Oh yeah, their oil meets minimum specs... but I want better oil than that.

Re: 2006 Escape Hybrid: Catastrophic Engine failure @ 65,000 miles
Further news on our 2006 FEH. We have it back from the dealer now, re-engined, and running fine. The only thing is, our mileage seems to have dropped from about 30-32 in the city, to around 20-22MPG. I'm wondering if we got an Atkinson cycle engine or an Otto for our replacement. Is there any way to tell from an external inspection?

they put an Atkinson engine in there.
That'd be a real kick in the behind if
you proved to them that they put the
wrong engine in there.

Yes, but it would be such an easy mistake to make
in the dealers parts department. Also an interesting
exercise in how much MPG savings you get using
the Atkinson engine. This is gonna be
REAL PAINFUL
for the dealer. They gotta make it right. Swapping
out that Otto for an Atkinson is gonna be
REALLY EXPENSIVE
the cost of the Atkinson has gotta be 3x what the
Otto is and he's gonna get it free. Almost easier
to just give'em the swap to Otto for free.

Best bet though is to make the dealer confirm by part number what engine went in.

Ford Motor Company has a policy of "only certified Hybrid techs" can work on the hybrid vehicles. If one is going the route of "the parts department" made a serious error, then you need to add the "person(s)" in the service department to this theory. It doesn't make any sense unless you want to go the route of "corrupt dealership".
Can we ask the owner to go thru a month or two of driving (break in?) and reporting back on fuel economy?

"@Bill Winney, I had no warning or indicator lights of any sort. If it had gotten hot, wouldn't I have had something light up?"
Of course it has a sensing mechanism for water temps. It just doesn't have the traditional gauge.
Wmmaness: the only difference between the Otto & Atkinson cycle engines is the intake camshaft. I wouldn't expect that dramatic a drop in mileage just from the different cam. There is a learning curve for the software in the engine. Track it for awhile and see if it rises.
