What side driver or pass, #1,3,5,7 or #2,4,6,8
Either way you will need a 12mm for valve cover bolts and a 10mm for the nuts attaching things to the valve covers. Once valve cover is off, you need to take out the back check valve out of the oil rail it takes a large hex sorry don't know the size off hand could tell you in the mourning I know the socket I use by heart just not the size, then you need a 30 torx to get oil rail bolts off 9 oil rail bolts. now you get to the injectors hold down bolt I believe on an 06 F-450 it is a 40 torx. Unscrew it by hand NO AIR TOOLS it can cause problems. Make sure the two o-rings are intact on old injector as well as the copper washer on the bottom surronding the tip of injector if any of those three parts are damaged torn or missing you could have more problems than you want to have. Anyway install visca versa. Torque on injector 24-26 ft lbs. torque on oil rail bolts 10 ft lbs and on oil rail check valve in the back usually around tight to 50 or 60ft lbs. Hope this helps Not that I know what I'm talking about or anything
