Problem started about 2 weeks ago. Driving on interstate pulling camper and all the sudden the 6.7 started to puff black smoke like a broke chimney. After pulling over and checking oil and other things had to get back on road. At next fuel station I added some Diesel Kleen and topped off the fuel tank. After about 45 min of driving and about 5 minutes from home the truck stopped visibly smoking while on interstate and then threw codes po263 and po264(cylinder 1 and 8 contribution codes). At home I drained fuel and changed both fuel filters. Truck was almost running right at this point but it would smoke more than normal. Used Forscan to monitor the cylinders and cylinder 1 would always show high + numbers (up to +14) in the contribution and cylinder 8 would always show lesser but negative numbers (around -6) . At idle all contributions go to normal. I have some recent blackstone labs test from as recent as 8k miles ago and the results were always within specs according to them.

No metal shavings found anywhere I looked in fuel system. Oil doesn't show any signs of antifreeze or metal. Antifreeze level is still good.

Today I replaced injectors 1 and 8. I used Forscan to program the trim codes of each injector and went on a test ride. Truck runs better but still smokes more than normal but I have only driven about 10 miles on the new injectors. I think I may have some head damage at this point.

Any ideas?

Thanks

 

Pull the glow plugs for those cylinders and have a look at the plug and in the cylinder if you have a scope.

What are you trim levels now?

 

I got home from work and got ready to do the scope but after getting to the glow plugs the long 8mm I had was not hollow on the inside. I will pick up a long hollow 8mm tomorrow and check.

I think I may have used the wrong term. I did not set the trim of my injector... I programmed the code from the injector into the PCM. Driving home from work today it was still going very positive on cylinder 1 and negative on cylinder 8 during the cylinder contribution monitoring.

I tried to do a PCM reset but forscan doesn't support it. I was hoping the computer would learn that new plugs were in place and stop the contribution adjustments from when the bad injectors were there.

 

if you are deleted are you running any hot tunes?

compression test should tell you if you have holes in piston or deformed piston.

aluminum piston's do not play well with high heat scenarios.

 

Just an update:

I scoped the cylinder with a camera... I didnt' see anything wrong but I am not an expert.
Every "BAD BOY SUPER COOL DIESEL LETS ROLL COAL MECHANIC" and "I RACE DIESELS AND KNOW EVERYTHING SHOP" in this area seem to be crack heads that lie and dont seem to know what they are talking about. I have been to everyone in town.

I decided to take it to the Ford service shop and they said they would find out what the problem was for $120 and they didn't care that it was deleted. On the first visit they ran a battery of test including the IDS relative compression test and a fuel system test and everything passed with no problems.

They said they didn't see any red flags and they reset the learned fuel trim for all cylinders and lets see what happens over the next few days. At this point the truck ran perfect for 2 days then on the 3rd day I started it up and cylinder 1 started to over compensate and the p0263 light came back on.

I took it back to the service dept. and they wanted to keep it a few days for prolonged test. The service dept manager has been honest and seems to actually want to get my truck running correctly.

I'll give another update when I get the truck back.

 

Got the truck back today. They say they hear stuff in the bottom end and I need a new motor. $6875.00.

I dont hear anything odd coming from the motor.....certainly not enough to say I have loose parts floating around in the bottom end.

To be clear the truck runs pretty good and just seems to smoke more than before and has the error code. I was thinking the most this would be is new heads but not an entire motor.


I dont currently own a tuner and I wonder if my tune could be messed up and I need to re-tune it.

 

Do an oil sample . The 6.4 is notorious for cam wear and lifter wear.

 

I would certainly seek a second option.

 

I have a sample in at blackstone labs since Thursday of last week waiting on the results. I have done samples a few times in the past and everyone was deemed pretty good for my mileages.

 

Ideas that come to mind since it passed compression and contribution tests at the dealer:

Try swapping a known good injector from another cylinder into #1 and run it and see if the code moves to the swapped cylinder. Also check the injector connectors/harness leading to #1. I know you replaced it, but it can't hurt to rule out a bad replacement.
How's the turbo?
For your own peace of mind, you might want to figure out who tuned it.

I replaced it with 2 different injectors for this reason.

I dont know how to tell but it seems fine to me. Sounds good.

Should I start with just buying a tuner and slap a tune on it?



I have attached my oil report. It also includes my last 2 test. It doesn't look to far out of the ordinary but I am far from an expert.

 

lower your oil change interval and keep your idling down.

That is about all that I see. That high iron is concerning without a reason for it.

I would pull another sample at 1K miles on it.

 

I did break a injector hold down bolt on the first injector change. Plus I did the injector three times.

I wonder if it's possible I dropped some iron dust in while I was doing all this work. I had to use an easy out to tap the broke bolt and back it out.


I will do another oil analysis at 1k like you suggested.

 

I got an ez lynk installed. Put a new tune on it. No emissions 0 HP tune. Still had the p0263 cylinder 1 code pop up.

Should I recheck the cylinder 8 injector? I still get cylinder 1 contribution going high in forscan and cylinder 8 going low.

my question is....... Can a bad injector in cylinder 8 cause cylinder 1 to over compensate. My problem is cylinder 1 goes very + on and cylinder 8 goes very - on the compensation test.

 

The pcm is great in the balancing act so the motor runs smoothly. I think your idea is possible that #8 maybe an issue.
