Just installed rods/pistons and I checked side play of rods big end and found that the one replacement rod (due to extremely spun bearing) measures .016 whereas others are about .011. My machine shop guy was glib enough to say "gee, 4 thou is nothing", but I will check with the re-builders group we belong to and double check the spec. Please note: my crappy Chilton's book give a spec for engines up to 1986, but lists no spec for later years. Mine is an 89 7m gte and want to do it correctly.
