Wow, I had not noticed. I'll have to look now. Still better than my 2005 6.0 was. It was always covered in oil from one place or another. I love the new 6.7 rust or not.

That's not rust, that's a patina. Some hotrodders spend big bucks for that look.

This is a Ford thing. Other makes still paint their iron blocks. Most companies don't paint aluminum components though.

The same thing will happen to various items under your truck and this is no different than the brake rotors rusting after they have been exposed to water.

difference is that you can’t paint rotors and they only rust when you don’t use them. The lack of paint is BS, and this is coming from a guy who had a driveshaft explode under his truck due to corrosion loss.

When you’re pumping out one million trucks a year, the cost to coat the metal is pennies on a per unit basis. Anyone who says different just isn’t right. Sorry. The real problem is that the bean counters aren’t stupid. You don’t need an MBA to figure out cutting $5 from a truck you make a million of every year gets you $5M in windfall profit.

Joke in the car collecting hobby.

What is the difference between rust and patina?

With that being said, it`s quite amusing to me that people complain about this on an expensive vehicle but don`t complain about it on an inexpensive vehicle. Cast iron is cast iron and regardless if it`s painted or not, especially in the northeast, that paint will wear off and the surface rust will appear.

How many iron blocks are still being used between all the makes.......that is the question.

So you`re saying that your Cummins block was rusty though..... right?
I guess that paint didn`t hold up to well did it. lol
