Thanks to all the great write ups on here everything went pretty well, had minor set back at the end… DO NOT RE USE FICM BANJO BOLT WASHERS! can’t believe that made it suck in enough air to run for about 5 min then die and no reason start but luckily someone on here put their .02 in and BAM! Fired right up. Just take your time and make sure you have all the tools for the job. I don’t have a driveway or a garage used a neighbors lot. Never owned a duramax before although had lots of fun vehicles and a few Cummins, for a young noob with no help other than the guys here you can do it! Definitely get rid of those awful Allen head and torx bolts on the covers and the lines and go with some hex head. I had two strip luckily was able to get thru them. Thanks guys, Cheers!
