All mileage is in kilometers not miles. The engine developed a 30% loss of compression in cylinder #1, so it's being rebuilt. Upon opening the engine, it was observed there was detonation damage to the head and broken ring lands on the piston in that cylinder. This oil sample was taken from the oil filter after the engine had failed. I will post further UOAs from the rebuilt engine under a different vehicle moniker (modified LT4 in C7 Z06). The major change is that it's going to go from a 6.2L displacement to 7.0L with a 2.65L supercharger (the OEM supercharger is 1.74L). This will allow for a lower boost which should hopefully work better in my track use.
Please note when I change the engine oil, there's still 2-3 qts of the original oil in the coolers, so use that to correct any additive readings with the previous fill.
