After seeing the last UOA, it was obvious the powdercoated intake manifold contributed (blasting media) to the high wear numbers esepcially the silicon.

New report is a lot better. Probably will have to stick to some short OCIs with some cheapo conventional or something to get all of the silicon out, but I'm glad this UOA is a lot better.

650 of these miles was a trip to Traverse City Michigan October 17-19th. A lot of up and down hill driving. A lot of highway driving at 70-80mph with 3-4 car passes with speeds of 90+ mph :)
