Hello All

I was told the following story by a fellow that had just dumped his 2016 diesel F250 and purchase a 2017 gas F250.

Here is what he told me:

The dealer told him the 2016 Ford diesels that were not used daily would cause an injection system failure that cost $16,000 to repair and warranty did not cover this. He went on to say the problem was when they sit unused water accumulates in the diesel fuel. The 2 filters in the frame just in front of the fuel pump (could be in back of Idon’t remember) would fill up with this water and the water sensing device would not work and cause the water to get in the high pressure injection pump and cause all this damage.

He uses this truck to pull his RV trailer so it sits for several weeks at a time.

My question is:

Is this correct?

Nope. I see diesel tractors sit all winter and fire right up every summer. Not sure what this guy is referring to. Is a machine and doesn't get tired or sick.However a truck that gets driven more often than not won't develop gasket leaks. Gaskets that dont get heated every so often will get hard and crack. They need oil to stay playable and soft.Not sure how much sitting your truck may see you didnt say but once you get your truck it may not sit that much. Mine is fun to drive.

 

Haha B.S. that guy got had. Now if you get bad fuel or put def in the diesel tank that's a different story.

 

There's some truth there. Water in fuel will cause major problems and ford doesn't like to cover fuel contamination issues. Ford has been trying to improve their filtration system each generation.

 

Hi The Bone

Agreed I just got a GM 4-71 running a few months ago that had been rebuilt 15 years ago and test run on the water pump it was mated to and the never run again. Other that the normal fuel hoses and coolant hose radiator flush etc the only thing I had to do was install a new starter and free one injector that was stuck. It has been running 24 7 for the last month. It did take about 30 hrs of running to break it in where it didn’t dribble oil out of the exhaust stack. LOL

Hi Rain Desert

The story I was told came from a guy that used the truck once a month to pull his RV trailer a couple of 100 miles.

I am not sure where the BS is coming from but while I am not exactly a crusader for the Ford diesels I do maintain 5 of them and in the environment they are in I think they are doing a very good job all off road.

The drivers we use can bend an iron bar in a pile of sand LOL

By the way besides the 5 ford diesels I supervise and maintain 5 Ford gas engine pickups, one F8000, 3 Tacoma’s, 2 Silverado Diesels, 2 Cats loader tool carriers, Kobelco excavator and 5 ATV one of them is a Kubota diesel.

Oh I forgot the 3 15 passenger swamp buggy 2 Ford and one Jeep Wagoner. All gas engines.

There's been enough "water in the fuel" failures that were really "DEF in the fuel" failures that Ford has a procedure for identifying DEF contamination to deny warranty claims.

 

My 6.7 has been flawless. I changed my fuel filter at 26,000 miles because I thought it was needed. When I hit 52,000 miles I will change them again. I have been all over the country in the last 3 months. I have used more than 1,000 gallons of fuel and not one problem with fuel. The new 6.7 has been bullet proof for me.

 

Sounds more like a sales pitch. "Did you hear the EPA was banning Diesel tomorrow, better get a gasser today."

 

"DEF in the fuel" is a $16k repair..

water in diesel has been an issue since the 1950's... nothing new...
Remember Oldsmobile diesel engines in there cars, most failures were water in diesel fuel.

if a concern... install an aftermarket water separator.

diesels do NOT like short runs.. but they do tolerate that more these days.

but that story sounds like a real good FEAR tactic for a SALE
45 years as a dealership mechanic... retired. ( Not Ford )

 

This doesn’t sound correct unless these trucks require the removal of the cab to get to the engine.

The Duramax cost about $6,000n to correct the DEF in the fuel tank problem but this is rare because the DEF filler is not next to the fuel filler.

Newer Ford trucks have a water separator in the fuel system and a sensor that tells you if you have the water in the fuel. Driving your truck only once a month and during the winter not at all wouldnt cause any problems. if you want you can always drain a little fuel out of the filter and no worries. If you want a diesel then get one and dont worry. You WILL love it.

 

do a SEARCH on this forum.. has happened a few times. read what the Owners had to pay..

Ford said.. new fuel tank and all lines.. pumps and injectors.. Everything the DEF MIGHT get in contact.... it's a corrosive
and Truck insurance will NOT pay for any of it.

 

Re: old diesel stuff back in the sixties and seventies....the big deal back then was the bacteria or fungi... whatever would start growing like crazy making slime. I guess they've got that licked now because it seems to no longer be an issue
