does the truck have a chip in it? do you use ford filters on it? i work at a dealership and i know that ford has been getting hard nose on those issues. still the 6.4v seems to be a good engine. have seen very few of them in our shop, especially when compared to the 6.0s. now that was a bad one.

Truck is bone stock. And yes the Ford dealer said it should have a FORD filter in it. No it has filters from Valvoline oil change places. I will tell you that we complained of the milage that it was getting way back in the beginning. It only gets about 12.5 miles to a gallon and that is being good on it. They said it doesn't break in tell 40-50 k on it. It falls to between 6.5-8.5 pulling trailer. I will tell you that my brother in law with a 08 GMC is getting 16-18 out of the box and gets 14-15 pulling 12000
pounds.

They absolutely cannot deny warranty on the basis of you not using their filters. There's been a law on the books for decades preventing that. It's called the Magnuson-Moss Warranty Act.

yeah they don't get any fuel mileage. been a complaint since day 1. sounds fishy that they are denying warranty work then. especially since it's under 3/36. i would try another dealer if you can.

You probably had an injector go bad and that is why your oil level was too high cause it has a weep hole that will spit diesel fuel into the crankcase. Normal oil change intervals is 16000kms or 10k in miles for the 6.4. Severe service which would include towing you would cut the mileage intervals in half. Call Ford customer relations and they should be able to resolve your concern. Was it a certified diesel tech that looked at your truck! I know that in Canada you have to be certified by Ford to work on a diesel if it has warranty on the vehicle cause I repair these trucks at a Ford dealer and it took me a bunch of training to get diesel certified by Ford. I hope you do not get screwed by the dealer that your truck is at, the 6.4 is not that bad of an engine either is the 6.0 IF they are maintained properly and not chipped. Hope this helps some

I agree with you 100% as a former Ford tech and now a city fleet tech. The 6.0 had many more problems than the 6.4 diesel. Yes the 6.4 is stuffed in there tight but so is the 5.4 gas and the V10. Not fun to work on but there are a lot of them on the road without near the probelms of the 6.0.
We have a 6.4 in a bucket truck and it went in for a recall on the radiator and to reprogram the pcm for an improved dpf filter cycle. Only other problem is the fuel transfer pump failed.

As long as it does not have a chip in it Ford should make good on the warranty. Get a hold of the zone rep and go from there. Sounds like your dealer is going to make you do the work. Good luck, Brian

you should check for recalls some of the 6.4s have a recall on injectors,
we have replaced 6 or 7 complete engines since the first of the year plus
3 or 4 short blocks, this should be warranty contact ford they need to
decide not the dealer
