No, only 3 that I have seen torn down in the local Ford shop. Two were shown to have used inline chips (brand not disclosed to me by tech.) The other was one piston melted on top from a bad injector that Ford could not prove to be someone else's fault. These were shown to me when I was talking to the techs about tuners, etc. I go to a dealer that has a commercial truck shop and the company I work for does alot of heavy truck work with them, so I know them fairly well, at least well enough that they recognize me and pull me in to show me things like this. All 3 of these were about a year ago, so they would have to be '03's or early '04's. The statement about the pistons melting before the turbo failing is from my knowledge of metallurgy, just to back that up a little. The pistons had the same pattern that SandKing mentioned in another thread, the square spray pattern that is outside of the cone on top of the pistons, his was possibly caused by the Banks system. I don't know how that happens exactly, just that the change in timing causes the fuel to be injected at a different point in the stroke and therefore combustion occurs over a different (larger) area on the piston. Now, there is no way for me to prove that the pistons they showed me were used on trucks with fueling boxes, I am just going on their word, and it's been true on everything else so far, I haven't caught them trying to snooker me. Have you seen any 6.0's with melted pistons or other parts failed due to high EGT's.

 

One other small note, if FMC had installed thermocouples in EACH exhaust manifold and monitored these temps, they surely could have made the PCM able to detect a failed injector b/c of the high temps in one side compared to the other and possibly have saved a few engines that supposedly fell prey to C94 injectors (not saying all the C94's are bad, but they did replace them for a reason, and I have read more than a few threads here stating that plenty of engines have had to be repaired extensively due to injector failures). Also, they could have given us boost gauges long ago, they monitor the MAP and could have T'd that off before and should be at bare minimum monitoring EGT's to help, well that and using a variable oil press sender and not a SWITCH... Ok, I'm done, sorry. Mat

 

The truth of the matter is that I have installed a pyrometer and other goodies. I have yet to see any EGT over about 1100. Just want to be on the safe side.

 

I never saw more than around 900-1000 on stock tune. Although Vic has mention that there were some '03's with bad programs that had what most would consider excessive and damaging EGT's.

 

Just to clarify I installed my probe in the exhaust manifold on the drivers side. I can only hope it's accurate when I strap the fifth wheel to it and start up the pass.

 

That is where mine is at.

 

If you install the probe post turbo you need to add a few hundred degrees (I believe it was 400) to the temp to get an acurate temp of the turbo.

 

What kind of temps have you seen while pulling?

 

My '05 with an air raid intake and no muffler will see 1200* empty if I stay in it from a light to say 65mph.
