Ford trucks are so strange, the quality is such a polarity. You either get a diamond or a lemon, nothing really in-between.
No...the 6.doh was all lemons. The only fix is to DESTROKE the truck.
The later ones (updated head studs) with a full EGR delete were OK. My buddy Jon's has been decent, but he went through two EGR coolers before just deleting the EGR.
- Branch tube adapters (revised to be a threaded style... he's had that done)
- Injectors (using Motorcraft fuel filters and changing them semi-regularly seems to prevent this)
- Use Motorcraft or International oil filters. Others don't fit right.
- IDM (Injector Driver Module) IIRC was another problem point. but the part isn't stupidly expensive and easy to change.
The 7.3L was certainly a less problematic engine and was generally much longer lived. But the 6.0L could be "updated" to be a decent engine, and aside from the EGR, that's essentially what Ford had done by the end of its production run.
It is unbelievable that International would produce an engine with so many bloody issues
They didn't. Their version (the VT365) is a decent light-medium truck engine. It was when Ford decided to crank the power up (325HP, versus a max of 225 in MDT's) that things went south. End result: it can be made sort of reliable after essentially re-engineering it.
Oh, the VT365 fails too. Just not as frequently. My buddy is a coach mechanic by trade, I've seen PLENTY of them apart. And they are prone to many of the same issues. The same goes for the Maxxforce 7.
The EGR cooler is the root of most of the issues with the 6.0L PSD (assuming you have a later one with the revised head studs) .
With the EGR deleted you get better gas mileage, longer oil life, the oil stays cleaner longer, you get less soot build-up, less/no intake runner build-up, coolant lasts longer....etc.
