What are you seeing with the Ford DI motors? Carbon build up on the valve tops?
I have a 2012 Focus with DI that's been great. It's hard to believe that a 12:1 2.0 motor can run on 87 octane and make 160hp. That's more than the 350 in my 71 Chevelle made.
How about the Ecoboost motors? They are all DI right?
Again, this may be mostly lack of care rampant here.
But yes.
2.0, 3.5, a few 2.3s.
The F150s that I serviced were city, records showed timely maintenance, But at 110k, when the heads were off.....it was atrocious.
The other ecoboosts I had to R&R were in the late 80 range.
Valves were sludged.
The chamber's themselves were caked.
Pistols were very crusty.
Now was that purely the cheapest 86 they could find?
Possibly, won't rule out owner habit.
But we had far too many earlier through 2013 range ecoboosts in with toasted heads.
Not saying it's a bad platform.
But having seen it, I'll pass.
But again, environment, owner care, etc wasn't ruled out when I said this.
I'm still willing to bet my heads look better.
When I motor swap/rebuild or whatever.
I'll make sure to look.
My 5.4 had 337000 when I tore it down.
Nowhere near as bad.
Rings had started to go, so I knew it was time.
And yes, Ford uses DI on their ecoboosts.
The plain Jane 3.7s in mustangs, trucks, and Lincoln's are still use sequential port injection.
Mostly saw those for water pumps
