Interesting update.
The piston on the '04 block that had the piece of the 2nd land fall out during inspection was also from cylinder #2. That absolutely reinforces my urge to get the injectors and maybe the rails tested further.
Maybe I should just swap to the '07 TGVs and fuel rails. I'd need to see the '07 injector maps to compare to the '04s...
There was also some slight lateral loading on one of the '04 rods which may mean it was slightly bent. Not cylinder 2 though... Slightly weird, but then again, 100K miles. Even something on the edge of tolerance might start a bit of wear. The rest of the '04 bearings and crank and even sleeves look pretty damn good cleaned up. we will see how much wear they actually got when I get it measured and/or rebuilt.
And my theory about load in the gap area was bogus. The rings actually rotate in their groves at double digit RPMs so it does not load or heat a specific area. Who knew???
