What would cause the valve guide tolerance to be .006 and not .001 to .0015? Is this something we all should be concerned with?:iono:

Well that is the interesting thing. I would think the fact that it had that much wear could have gone in my favor or not in my favor. What I mean by that is with that much wear, it would consume "too much" oil and that allowed this to be covered by warranty but one could also argue that it had that much wear due to lack of oil.

Ring gap lined up on the cylinders?

They only inspected cylinder 1,3 and 6 and it was only cylinder 3 that had the gaps lined up. I did a lot of reading on ring gaps and most every site I went to said you install them 180 degree opposite. But then about 70% of the sites said that once installed, they will freely go wherever they want and whenever you pull apart an engine it would not be uncommon to find them lined up in some cases.
My personal thought on it would be that yes they are free floating so it would be possible to line up. But once they line up ,there would be nothing to encourage it them to un-align themselves and the gap would stay. You would loose power on that cylinder, you would have power loss and oil loss. Then over years of use the rings on the other cylinders would be ever so slightly moving around and then another one might line up. Just my theory...Maybe far fetched but with the oil being able to flow through the gap with ease it would be encouraged to stay like that.

Great news! So is it possible that the oil pressure is the culprit on some of the cars that had engine failures. Is it possible because the ring gap was letting in oil into the cylinders causing not enough pressure to oil the timing chain properly. Just a theory.

Yeah it could be. While searching for theories on my car I found this PDF about 40 reason for too much oil consumption

It has all sorts of things that could be causing issues.
