Long story short, it looks like the Jeep needs cam phasers after almost 160,000 miles. While I’m in there
I’m gonna replace the rockers & lifters.
Finally got everything installed in Bank 2. (Didn’t take a photo. It was too dark and I was too tired.) Just need to torque everything, replace all the valve cover gaskets before finishing up.
PRO TIP: Replace the gaskets around the spark plug wells and the cam position sensors before they become old and brittle. They’re needed to seal out debris and will drop bits & pieces on the cams and rockers as they deteriorate.
Inspected each rocker and cams. Everything was in good shape except 3 or 4 rockers had a tiny bit of radial play. They probably would have lasted another 30 or 40 thousand miles, but I’m glad to catch them now.
After buttoning up Bank 2, I’ll tackle Bank 1.
PRO TIP: The YouTube guys always leave out something when posting videos about “How Easy It Is To Do It Yourself”. Like how the specialty tool for relieving spring tension may not push far enough to install the pin to hold the tensioner out of the way.
