UOA is in and no issues found up one PPM on lead is the only difference, so I'm stoked! Only 3 wear metals are present all are low (4PPM and under normal for this engine and mileage for a total of 9 vs 8 PPM wear metals.
Too many variables and lack of a statistically significant increase for the lead count to mean anything (could literally be anything or nothing at 1 PPM difference). With sustained freeway speeds, sustained long grades with hard pulls, different environments, different oil and unknown use and mileage on previous as bought oil from the other sample it appears the engine is fine and healthy!
So moving forward with a compression check followed by proper upgrades if SAT after my custom exhaust goes in next week!
