[DeTomaso] Ford Eco-boost engine problems (NPC)

Sat Dec 22 14:52:41 EST 2012

I did some internet research but found nothing conclusive.  From what I saw, 
shooting the fuel into the cylinder might be hitting the cylinder walls with 
liquid fuel, cold starts are very rich to get the post-turbo cats to light up, 
the high pressure system might just be leaking into the engine.

You'd think they would be closing the intake valve before they shot the fuel in 
... so intake valve deposits are a puzzle.  Contamination via the PCV system was 
sometimes cited.

Best observation I saw was: "Instead of useful utensils, modern engines ( and 
cars ) are laboratory experiments".

To which I might add:  We're surrounded by ever more complex technology, while 
the population on average grows less technically savvy with each passing day.

They're DI & turbocharged Guido, and the bigger ones at least, are twin 
turbo.
I think we're going to learn some interesting stuff as we see the first 
big population
  of this engine type get on into the higher mileages.
Oil-dilution, increased wear rates, heavy intake valve deposits, 
crankcase venting issues etc. (so far).
In five years it will likely be well understood and corrected.
(mind you GM has just confirmed that they're committing to DI, non-turbo)
