2020 6.7 Power Stroke w/Steel Pistons
Here's a video from Mr Truck. He missed it, but the new Power Stroke will have Mahle Steel pistons. This should make this engine platform good for an easy 1 million miles.

- Wow, I was questioning the post on the steel pistons so I looked it up and sure enough, it's something that performance diesels have been using in their racing engines for a while. I never would have thought a steel piston would work because of the inertia weight. Apparently they've beefed the rods up to compensate.

If they would add real Corinthian Leather, then you would really have something.

Pistons may go that long but what about the ZILLION other parts???
What the two extra cylinders? Yeah OK...wrgrs50s wrote:

Most of your HD diesel engines now use steel pistons and is the major reason most can get 1 million miles without a rebuild.- With the slower rpm of the diesel engines steel pistons are definitely possible. Trying to run steel pistons in a high rpm engine may cause UFO's as parts try to leave the engine bay. :)

There are many HD diesel engines that go a million miles and don't use steel pistons. The ability to go a million miles before an overhaul is generally not due to piston material. Worn sleeves and piston rings along with bent rods are generally causes of an overhaul in a million mile HD truck.
Also, one of the biggest factors in an HD truck making it to a million miles has a lot to do with how it is driven and of course maintained. An HD long haul truck that is on the road more often with minimal cold starts will easily get to a millions miles while the same truck used as a delivery truck with a lot of stop/starts will probably no get to a million miles before an overhaul.ShinerBock wrote:

I don't disagree with most of your comments but I do disagree that the steel pistons are part of the HD engines durability. They wouldn't install a more expensive piston if they didn't increase the longevity of the engine.
I believe these are the Mahle pistons going into the new Power Stroke since Mahle already provides the current aluminum pistons to Ford.

LOL, I never realized that aluminum pistons were holding the SD back from the million mile mark.
Wow, learn something every day! :B
LOL... When I saw these new Steel pistons going into the new Power Stroke you're the first person I thought of since you were the one stating the new 5LP Duramax was going to have these pistons.
Even though I knew you were joking at the time. :W- Comming soon...a TV commercial featuring A load of bricks being dropped onto a steel piston, versus A load of bricks being dropped onto an aluminum piston.
