Started assembling this seasons Nova mill. Found out Mahle has some serious quality control issues... One pack of gapless rings has .060 on the second ring, and .037 on the top ring right out of the pack! Had a second set of gapless that were for Jason's ovals from Danville. That set was .045 second ring set, .050 top ring set. All holes/rings were checked at center and square in the bore. Got another set coming Monday from Guy, guess he has been seeing issues as well.
