    Some advice - my ringland on piston 6 is toast. There are a couple 1" diameter glaze spots on the cylinder wall from the peice of ring pressing on it. The glaze spots are smooth to the touch. Dealer says its cool to just drop in a new piston. Can anyone verify this for me ?

    So what caused it to fail in the first place?

    Well the truck is trd supercharged with 50k on the blower and was running for 10k with a heat range 6 plug gapped at .044. So that didnt help considering the plug that should have been in there is a heat range 7 at .032.... My guess is from running too lean, but this was diagnosed because of oil consumption/oil blowing back into the intake / smoke on startup. It could be the trd software was too agressive. I have heard they put ont new software with their blowers for the tacoma & tundra that neuters it drastically...
