I'll make a guess and say "yes". I think the general piston design with oil passages are the same. They just made the diameter slightly larger, and I "assume" they changed the pin boss location slightly to try and compensate for the change in CG. If they didn't...Oh boy..
Yes, it turns slightly milky. Almost looks like aerated oil. Not quite that bad, but noticeable.
I here ya. When you think of an engine design though, it's a question of design and needed lubrication. For example... You could design an engine to easily run on 5w20 oil with 72,000psi shear strength. If you ran the same engine with water as a lubricant, it would fail. But you can still claim that water is a lubricant. When you make a change to an existing engine design that did fairly well with a certain lubricant, those changes may start going beyond what that original lubricant can provide. Ceratec, is not snake oil. There are definitely snake oils on the market. In fact most are just thickeners that do very little. My point, is that regular motor oils are adding more and more of these Boron nano-particle type lubricants to enhance capability to the base stocks. That's why guys switching from Motorcraft 5w20 to Pennzoil UP 5w30 are having success. Or even staying with Motorcraft 5w20/30 and adding Ceratec, also having success. The problem is, we are switching "after hearing the problem". That means we are providing the proper lubrication to an engine that "may" have already suffered a small amount of damage.
I assure you they have a "clue"
Ford wouldn't replace short blocks without knowing what's going on. We never hear what the root cause(s) are because dealers usually don't do a complete tear down and detailed inspection because they would lose their butt big time on a warranty jobs, which is already paying less than If it wasn't a warranty job.
If that statement were true then why are people that had short blocks replaced still having the same issues, Ford put a car into service with a faulty engine and or design flaw until they resolve the issue their credibility has slipped down a few notches in my book. This problem is being played down by many saying it's only a small amount of cars that are affected, yet there are new videos popping up almost daily about the issue. This problem is bigger than most people realize and you will continue to see more and more popping up.
Maybe Ford replaces short blocks because they know it's a manufacturing issue, not a design issue. Maybe they can't tell which short blocks sitting in the warehouses are good vs bad, so they roll the dice since they aren't going to tear eac one down and inspect before shipping out. That's why some guys get a replacement short block that goes south too. Some guys get a good short block and don't have a repeat ticker.
I wonder if knock sensor is fooled by the rod/piston/whatever sound and is retarding ignition.The data files show an adjustment for piston slap. I wonder if our lower power rhd cars have a more conservative map?
