I was heading out of town a week and a half ago pulling a load I'm guessing to be around 14,000 lbs of construction material (my tractor is 12,500 and it was heavier). I started to climb a slight grade when truck shuddered like U joints were going out or something. I got off the pedal and it stopped but as soon as I got back on it, same thing. Let off again, put it in neutral and reved it a little and it shuddered and missed out badly again. Pulling over to the side of the road and put it in park and it was shuddering, loping, missing or whatever you want to call it like I had a huge oversized cam and had a little white smoke puffing! Oh man! No engine light or codes yet.
I turned it off, popped the hood to check for puking. Fluids were fine and no puking. Pulling engine oil dipstick and it smelled burnt! Oil had only 1,500 miles on it since it was changed. Started it back up again with same results but this time engine light. Check the codes with DashDaq and got Cylinder 6 misfired and Cylinder 8 Contribution Balance I believe is what it said. My brother came and picked up the trailer and I was able to make it back home (about 60 miles) to put it all back to stock. While switching the CAI out with the stock filter, noticed oil in the turbo, quite a bit of it.
Took it to the dealership (sh!!tin my pants). This was Thursday the 7th. Service writer called me on Tuesday the 12th and wanted my maintenance records. That was fine, had good records of all that. She (service writer) told me the tech told her he was leaning towards a turbo and rocker arms!! Huh!! She said she was certain that Ford would want the records. The remainder of last week I heard nothing and truthfully was scared sh!!tless to push the issue.
I called them this morning and she said they were still waiting for approval to proceed from Ford and that it was a turbo. I just don't believe that it's a turbo but here again, don't really want to argue with them just yet until I find out if it's going to covered or not.
Sorry for the long read but just am looking for opinions. I feel that it's related to alot of the same issues that's been happening like stuck injector that's melted one or more of the pistons.
