Hi! A little background first.
I have a 2008 F-150 with the 5.4 v3 engine. For the most part, its an awesome truck and does everything I need it to do.
I purchased it Jan of 2018, and just before purchase, the entire timing system was rebuilt, chain, tensioners, cam phasers, sensors, everything.
Last weekend was the first signs of concerns with the phasers again, after a complete warm up, the engine would stutter and stop
at almost every red light. Not too sure if I want to go through a $3,000 bill again to have (most of) the system redone again.

So... I'm looking at a 2015 F-150 with the 2.7 eco boost engine. Its in super shape, and only 46,000 km on it.
Has all the options I'd like to have, and drives oh so sweet!

I have a 21 foot TT that weighs under 5,000lbs loaded, and from what I understand, the 5.4l and the 2.7 eco are very close in towing capacity.
So Its a good match. The 5.4 pulls the trailer like its not there.

So after a little research, I see it has some sort of plastic oil pan! With a leaking issue that can't seem to be fixed properly.
Reports of the oil pan being redone 2-3-4 times...
How big of an issue is this, and is there a metal replacement that fixes the issue?

Second big concern is the carbon buildup on the intake valves. Seems like a lot of issues there too, but common and the DI engines everywhere.
Is there a maintenance routine to help prevent the carbon buildup? Will a catch can help?
Preventative measures for the buildup?

Any and all info will help. and thanks in advance.
Will be making the purchase Saturday afternoon of all goes well, trading in the 2008.
Anything I should specifically look at before purchase?

Thanks!
Chris

Find one legitimate case of carbon build-up on a 2.7. There are none. Scratch that off your list.

Does the oil pan leak now? If no, then it probably won't ever. Most don't. If it does, have the dealer fix it before you'll take delivery. A competent dealer service dept. can fix it properly the first time.

Take a nice long test drive, through a variety of roads & speeds, and verify all options & functions. If it feels good, and drives well, buy it. If it doesn't, walk.

Good luck.

Exactly.

Agree 100%

I came from a 2005 5.4 to a 2017 2.7. Excellent upgrade.

Serious question: If carbon buildup was never an issue, why did Ford add the cost and complication of dual injection in 2018?

Thanks guys... everyone seems to talk highly of the truck.
I'm fairly confident that it will be a good choice.

How do you find out what version of SYNC is installed? - Is it easy enough to update, or should I have them do it?
Would it be far to ask they update the maps at purchase? I hear its 150 bucks to have it updated.
Okay, googled a little. Seems I have to have the dealer ensure/update to the latest SYNC in order to run the most resent maps.

Emissions.
Soot.

I've also heard that it reduces emissions, but I cannot state that with authority.

From a Car and Driver article of dual injection used by many manufacturers........https://www.caranddriver.com/news/a1...ect-injection/

"Peter Dowding, Ford’s chief engineer of powertrain gasoline systems, revealed a different strategy. Ford uses PI alone at idle and at low rpm for smooth, quiet, and efficient engine operation. As rpm and load increase, fuel delivery becomes a programmed blend of PI and DI. In contrast to Toyota’s methodology, Ford’s PI is always operating, responsible for at least 5 to 10 percent of the fuel delivery.

Dowding and his Ford engineering colleague Stephen Russ stress that carbon deposits on tailpipes and intake valves have never been an issue in their DI engines. Dowding adds: “Now that electric motors are being assigned increasing propulsion roles, our task is to improve engine efficiency whenever we can. Ford’s dual-fuel technology has already proven to be a valuable, cost-effective strategy in this effort.” "

Searching the F150 forums for somebody having a carbon problem confirms this.

I believe it also adds a bit to FE, which is what everyone is chasing these days, thanks to CAFE.
