Etwenty1 45 Report post Posted March 30, 2013 I picked up a nice e30 325i with blown hg, have removed head. po stated hg had been done by reputable indy in tga a year ago, Issue is that while removing rocker shafts, a deformed channell for locking plate has scored shaft journals in head and the rocker bushes. wanting to know if this is a major. Am thinking the shafts are held in place and rockers move so maybe just the rocker bushes? Quote Share this post Link to post Share on other sites
