[m6-lt1]

While it is a lifter, as he pointed out it wasn’t the usual failure where the AFM part of the lifter gets stuck. The roller failed for some reason. This engine had its oil changes on time so I wonder if it was tracked a bunch. Lifters aren’t going to last forever in a road coursed car. 2018 was a solid year in terms of LT1 quality as it was built well before the post covid engines that seem to be spinning rod/main bearings.
