About This Video

In this video I’m replacing the valve cover gaskets and spark plugs on a Dodge Ram 1500 with the 5.7L HEMI. If your truck is leaking oil, you’ve got oil down in the plug tubes, or you’re getting that burning oil smell under the hood, this is the step-by-step process I use in the bay. I show you how I pull the intake/air box, unplug and remove the coils, free up the harness and hoses, and get both valve covers out—even with the tight back corners by the firewall. I also go over the parts and supplies that matter. I like the Fel-Pro kit that includes the rubber bolt grommets, because those harden up and can be the actual cause of the leak. While the covers are off, it’s the easiest time to do plugs on a HEMI (16 total, two per cylinder). I install NGKs dry (no anti-seize per NGK), run them in by hand, and torque them to 13 ft-lb. For reinstall, my big tip is using a very thin bead of 3M black weatherstrip adhesive to keep the gaskets and tube seals from falling off while you’re feeding the covers back in—then I verify with a mirror and flashlight before tightening the bolts (about 6 ft-lb) in a star pattern.
