coullstar 0 Posted September 11, 2009 There is a hint of that on one or two. Im pretty sure bottom right and top left are 1 & 6 that are prone for the oval bores. Some of them do have the brown tinge which is what you want. Here were what my 1&6 looked like when it started blowing oil on the overrun. Quote Share this post Link to post Share on other sites
