Could someone explain the design defect to the less mechanically inclined?
Looking at the photos one page back the Ford block has a strange empty space around each piston portion. Is this lack of rigidity causing the Ford pistons to move and wear away the wall lining?
This article does a good job summarizing open vs. semi-closed vs. closed deck blocks:

I had no idea Ford went with a fully open deck block. What's Honda doing for their Civic Type-R? A quick search says the turbo versions are the K20C1, 2, and 3 as opposed to the more famous normally aspirated versions which are K20A, B, and Z for example. Does anyone know if the K20C in the new Civic Type-R is also open deck like the rest of the K-series engines?
Is it purely an under high boost issue, or maybe something to do with warm up (metal expansion) and boost?
The engineering behind warm up expansion can be quite complicated too.
I saw a 3 rotor Mazda build video a while back on YT that showed the two piece crank (e-shaft) and floating mount of third rotor housing.
I was blown away...it was like a normal two rotor engine with a floating third rotor added- all because the hero sandwich design of a rotor engine had way too many heat expansion issues if hard mounted.
Road and Track has a different theory:

The "using the wrong head-gasket because easy to get them mixed up at engine assembly plant" makes more sense than Ford intentionally making a media hyped car with an engine block that flexes too much under boost, causing a failed head-gasket.
Yep it is, and what'll probably happen is that all of the gaskets will have that extra passage from now on, assuming it isn't detrimental to the Mustang 2.3. Basically, every gasket will be the Focus RS gasket, that'll make the revision version essentially idiot-proof (don't quote me on that)
You can say "One Ford", but that still doesn't mean exactly the same.
Any response from Ford about the possible head-gasket part mistake causing the issue?
The news reports from earlier this month suggest Ford admitted it was a block issue....
Did Ford actually say this, or are people reading between the lines (too much) to add new info and add site traffic?
So I am still confused.
3% of cars being impacted is pretty high, especially given the results of a failure and at the low mileages being reported. Matt sounds like a butthurt Focus RS fan boy.
how come a transvestite donkey witch is next to you and why is it wearing a dress?
Say 'what' again. Say 'what' again, I dare you, I double dare you mother****er, say what one more goddamn time!
