Nissan needs a engineering fusion with Mercedes for a V6 VVEL Twin Turbo Direct Injection engine...
There's nothing wrong with the design of the VHR, if engines are legitimately burning oil regardless of break-in procedure, the fault lies in quality control. Maybe they forgot to plateau hone some of the cylinders! Whoops!

Who knows? Nissan of course will never admit what went wrong, but I'd like to get a hold of a failed short block to see what the cylinder walls show.

We need to hear from some tribologist' or at least some UOA's analyzed by triboligists and not just the data from labs like BlackStone.

True NNA will never admit failure or quality control on a TSB. A recall is a different story. My dealer did not even have the authority to tear it down. All of the dealers were instructed by NNA to ship the bad long blocks (untouched) back to Nissan in Tenn for inspection. The bro had one of the first replacement engines, when they were still being hand built in Japan.

Note: I am referring to the 06 RevUp long block.
