A 30 year guy at the Flint yard said my injector lines looked like "spaghetti in a lunchbox" and he was right
Two winters back I was doing a head gasket on a 6.7 in my buddy's unheated garage in Flint and I ran the injector lines back on any which way, just snugged them down and called it done. A retired diesel guy named Walt who hangs around the yard watched me button it up and said, and I quote, "that looks like spaghetti in a lunchbox, son." I got defensive at first, honestly, because it started and ran fine. But he pointed out how crossing two lines let them rub on the intake horn, and after maybe 8,000 miles that rub turns into a pinhole leak you won't catch until you smell diesel in the cab. So now I lay every line out on a bench in order before it ever touches the block, and I never tighten the hold-down clamps until all six are seated loose. Took me an extra 20 minutes per job and I have not had one comeback for a fuel smell since. What bugs me is how many guys on here probably still slap them on in whatever order fits. Does anybody else do the bench layout thing, or am I overthinking a job that usually works out anyway?
