What to get????

to add the EPA stuff there was too much work to be done to the 7.3 so they started over with the 6.0 and ford changed some things from international that is part of the problems

EPA 04 and 07 was tough on everybody. Some faired better than others. A complete platform redesign to accommodate emissions and EGR was common.

There was likely no was the 7.3 could have been adapted.

The HD platform that I work with has been plagued by issues, and no manufacturer was spared in the loss of performance, mileage and reliability.

The mods that are available to subdue these issues on the 6.0 seem pretty solid

The big truck diesels from 06-10 really suck bad. They bogged them down with so much crap that they don't have any longevity whatsoever. The newer 13 and 15 liters seem like the urea has let the engine breathe much better and better mpg too.

They changed to the 6.0 due to EPA and emissions shit and the tuning isnt the key reason they were blowing gaskets. Failed egr coolers and bad oil cooler design along with people tuning them without knowing what warning signs to look for.

We have had one of our 6.0s removed and replaced TWICE in a (lower output) E-Series...and another one in an F-series with 11K on the clock. These are 100% stock veicles.

Retuned? Matt are you saying the 7.3 has been engineered and adapted to EGR for those MY emissions standards?

I mean aftermarket tuners. You could load a hell of a tune into a 7.3 PCM and it would just keep on chugging.

No...Ford IS the problem. Navistar didn't have NEAR the issues with the 6.0 as Ford did. Ford marketing got ahold of the engine's specs and said that the numbers HAD to be higher so the engine looked good on paper.

There is a reason why the Navistar version puts out 200-210 HP while the Ford churns out 325.

It was a high-strung diesel....it's similar to the egoboost engines. Very high strung. Just wait until they start failing.

im not saying that there were bad engines in the lot but im willing to bet that they failed and were replaced with the root cause being the failed oil cooler and egr cooler

my 6.0 and daves 6.0 are both tuned and stock. mine was stock till i did the oil cooler cuz when my ac was done in june the coolant was replaced with the wrong coolant causing the system to fail and clog with the old design. otherwise it hasnt blown a head gasket and was stock till 173K

the oil cooler design used was/is terrible. even the updated version is bad. this is the root and main cause of the failures. with out eot and ect gauges you cant tell if the truck will fail and start leaking coolant into the heads and cylinders. thus causing the head gaskets to blow. and that happens stock or tuned regardless. that and the international versions had a coolant filter which is something ford took out when they put it in the SD

Maybe the one to blame is EPA and its bunch of stupid bureaucrats

Until 2005 or 2006 there were still some versions of the F250 and F350 fitted with the 7.3 for export markets, while American customers were experiencing failures with the 6.0...
