Agreed
However, they're susceptible to fuel dilution. The 2.7L has a TSB about breaking cylinder walls. I'd be looking for that with the 2.7L.
I have never heard of this. Do you have a link?
The ram Eco diesel does have a problem breaking cylinder walls,
Thanks.
I might have miss spoke thinking of long block replacements but heres the TSB I was talking about.
Ford TSB 17-0007
Here is a summary of the text from the TSB:
FORD:
2016 F-150
ISSUE
Some 2016 F-150 vehicles equipped with a 2.7L gasoline turbocharged direct injection (GTDI) engine and built on 1-
Apr-2016 and through 1-Oct-2016 may exhibit white or blue smoke from the exhaust, rough idle in neutral or park at
normal operating temperature or after a hot restart. The vehicle may also exhibit diagnostic trouble code (DTC) P0300,
P0301, P0302, P0303, P0304, P0305, P0306, P0316, P0524 and/or P06DD with the excessive oil consumption. Oil
consumption may be 1 Liter (1 quart) in less than 4,800 km (3,000 miles).
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Connect the Ford Integrated Diagnostic System (IDS) service tool or equivalent scan tool to the data link connector
(DLC). Check for DTC P0524 and/or P06DD with any misfire codes stored in the powertrain control module (PCM)
memory?
a. Yes - replace the engine long block assembly. Refer to Workshop Manual (WSM), Section 303-01.
b. No - replace the cylinder heads. Refer to WSM, Section 303-01.
This is what I have translated out of this TSB and the hearsay
from the F-150 Forum.
I think the guides are bad. Why? Don't know. Bad material. Incorrect installation. Inadequate design. Driving conditions. Inadequate oil. Who knows?
At some point, the guides start letting a lot of oil by, enough where the sump is depleted in 200-300 miles,(Why you wouldn't notice this coming out the exhaust is beyond me, but hey...). At that point, the engine blows.
If the problem is caught before the major sump depletion, then the heads are replaced, which is the source of the issue. If the sump depletion happens, the engine is damaged, and the long block is replaced.
This may not be exactly accurate, but I think it is in the ballpark. I really have a lot of questions about this whole thing, that I will probably never get answered.
